INTERSIL LM139/339 Voltage Comparators FEATURES GENERAL DESCRIPTION Wide single supply voltage range or dual supplies The LM139 series consists of four independent precision Very low supply current drain (0.8 mA) voltage comparators with an offset voltage specification independent of supply voltage (2 mW/comparator as low as 2 mV max for all four comparators. These were at+5 V) designed specifically to operate from a single power sup- ply over a wide range of voltages. Operation from split Low input biasing current 25nA power supplies is also possible and the low power supply Low input offset current +5 nA current drain is independent of the magnitude of the and offset voltage +3 mV power supply voltage.

The MOS and CMOS logic systems LM139 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, they will directly interface with MOS logic where the low power drain of the LM339 is a distinct advantage over standard comparators.

For operating at high temperatures, the LM339 must be derated based on a 125C maximum junction temperature and a thermal resistance of 175C/W which applies for the device soldered in a printed circuit board, operating in a stilt air ambient. The LM139 must be derated based on a 150C maximum junction temperature. The low bias dissipation and the ON-OFF characteristic of the outputs keeps the chip dissipation very small (Pp, = 100 mW), provided the output transistors are allowed to saturate. 2. Short circuits from the output to V* can cause excessive heating and eventual destruction. The maximum output current is approximately 20 mA independent of the magnitude of V*. 3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V* voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will reestablish when the input voltage, which was negative, again returns to a value greater than -0.3V. . These specifications apply for V+ = 5V and --58C < T, = +125C, for the LM139. The LM339 temperature specifications are limited to OC =sT, = +70 . The direction of the input current is out of the [C due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the reference or input fines. . The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V* 1.5V, but either or both inputs can go to +30V without damage. . The response time specified is for a 100 mV input step with 5 mV overdrive signals 300 ns can be obtained, see typical performance characteristics section. . Positive excursions of input voltage may exceed the power supply level. As long as the other voitage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than 0.3V (or 0.3V below the magnitude of the negative power supply, if used). 9. At output switch point, Vo = 1.4V, Rs = ON with V* from 5V; and over the full input common-mode range (OV to V* 1.5V). 10. For input signals that exceed V*, only the overdriven comparator is affected. With a 5V supply V,, should be limited to 25V max, anda limiting resistor should be used on all inputs that might exceed the positive supply. an Oo oO fs 5-43LM139/339 TYPICAL PERFORMANCE CHARACTERISTICS [INTERSIL SUPPLY CURRENT INPUT CURRENT OUTPUT SATURATION VOLTAGE 1.0 10 T, = -55C A Vin com = OV OUT OF R = 1092 > SATURATION o8 Ta = 0C IN (CM) = < Qo 10 = < F os +25C 2 w " > T, = +126C eS 2 A 5 T 6 0.1 2 ra = 70C = Ty = 55C > (4 q z s & =+125C ze a 0.2 Tq T4125C 1, = +25C & 0.01 RL ze Ty = +70C 2 9 0. o 10 20 30 a0 a 10 20 30 40 n,01 0.1 1.0 10 100 tg OUTPUT SINK CURRENT (mA) SUPPLY VOLTAGE {V) SUPPLY VOLTAGE RESPONSE TIME FOR VARIOUS RESPONSE TIME FOR VARIOUS INPUT OVERDRIVESNEGATIVE TRANSITION INPUT OVERDRIVESPOSITIVE TRANSITION 6.0 6.0 wi 5.0 mV = INPUT OVERDRIVE wi INPUT OVERDRIVE = 100 mV g 5.0 9 5.0 5 FS a 4.0 a 40 = 3- 22 30 z= 30 5 PF 5S 5 2.0 & 2.0 - 2 10 1.0 . 0 i 0 < c 9 ES 100 ae dE QE -50 on ') ez rz >> -100 2> 0 2 2 0 05 10 15 20 TIME ( sec) TIME { sec} TYPICAL PERFORMANCE CHARACTERISTICS LMz290 SUPPLY CURRENT Ty = 40C Ty 70C Ty = 425C SUPPLY CURRENT {mA} li INPUT BIAS CURRENT (nA} 10 20 30 40 10 20 SUPPLY VOLTAGE (V) RESPONSE TIME FOR VARIOUS INPUT OVERDRIVESNEGATIVE TRANSITION 6.0 ui 5.0 mV = INPUT OVERDRIVE g 5.0 = a 4.0 4 a- Sz "7 55 3.0 Blk vi, & 2.0 OUT 2 9 10 wt o @ = 0 32 se -50 5 -100 = < 0 0.5 10 (18 2.0 TIME ( sec} 5-44 INPUT CURRENT A = +85C SUPPLY VOLTAGE (V) 1 OUTPUT SATURATION VOLTAGE 10 = o 1 = 2d Ty 7 +85C | 2 Ty =+25C Zoopla = = A < 2 Lf g 21 Z T x -40e | 2 0.001 30 40 0.01 0.4 1 10 100 ig, OUTPUT SINK CURRENT (mAt RESPONSE TIME FOR VARIOUS INPUT OVERDRIVESPOSITIVE TRANSITION 6.0 5.0 40 INPUT OVERDRIVE = 100 mv 3.0 2.0 1.0 0 OUTPUT VOLTAGE, Vp (V) 100 50 0 HNPUT VOLTAGE, Vin (mV) TIME { sec)LM139/339 APPLICATION HINTS The LM139/339 are high gain, wide bandwidth devices which, like most comparators, can easily oscillate if the output lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance. This shows up only during the output voltage transition intervals as the com- parator changes states. Power supply bypassing is not required to soive this problem. Standard PC board layout is helpful as it reduces stray input-output coupling. Re- ducing the input resistors to < 10 k 9 reduces the feed- back signal levels and finally, adding even a small amount (1 to 10 mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback are not possible. Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relative- ly fast rise and falt times, hysteresis is not required. All pins of any unused comparators should be grounded. The bias network of the LM139 series establishes a drain current which is independent of the magnitude of the power supply voltage over the range of from 2 V to 30 V. It is usually unnecessary to use a bypass capacitor across the power supply line.

Protection should be provided to prevent the input voitages from going negative more than --0.3 V (at 25C). An input clamp diode can be usd as shown in the applications section. The output of the LM139 series is the uncommitted col- - lector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output ORing function. An output pull-up resistor can be con- nected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage which is applied to the V+ terminal of the LM139A package. The output can also be used as a simple SPST switch to ground (when a pull-up resistor is not used). The amount . of current which the output device can sink is limited by the drive available (which is independent of V+) and the B of this device. When the maximum current limit is reach- ed (approximately 16 mA), the output transistor will come out of saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the approximately 60 r,. of the output transistor. The low offset voltage of the output transistor (1 mV) allows the output to clamp essentially to ground level for small load currents.
