MAX941/MAX942/ MAX944 High-Speed, Low-Power, 3V/5V, Rail-to-Rail, Single-Supply Comparators General Description The MAX941/MAX942/MAX944 are single/dual/quad highspeed comparators optimized for systems powered from a 3V or 5V supply. These devices combine high speed, low power, and rail-to-rail inputs. Propagation delay is 80ns, while supply current is only 350A per comparator. The input common-mode range of the MAX941/MAX942/ MAX944 extends beyond both power-supply rails. The outputs pull to within 0.4V of either supply rail without external pullup circuitry, making these devices ideal for interface with both CMOS and TTL logic. All input and output pins can tolerate a continuous short-circuit fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The MAX941 features latch enable and device shutdown. The single MAX941 and dual MAX942 are offered in a tiny MAX(R) package. Both the single and dual MAX942 are available in 8-pin DIP and SO packages. The quad MAX944 comes in 14-pin DIP and narrow SO packages.

The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis zone (see Figure 1).

Input and Output Waveform, Noninverting Input Varied Detailed Description The MAX941/MAX942/MAX944 single-supply comparators feature internal hysteresis, high speed, and low power. Their outputs are guaranteed to pull within 0.4V of either supply rail without external pullup or pulldown circuitry. Rail-to-rail input voltage range and low-voltage single-supply operation make these devices ideal for portable equipment. The MAX941/MAX942/MAX944 interface directly to CMOS and TTL logic. Timing Most high-speed comparators oscillate in the linear region because of noise or undesired parasitic feedback. This tends to occur when the voltage on one input is at or equal to the voltage on the other input. To counter the parasitic effects and noise, the MAX941/MAX942/ MAX944 have internal hysteresis. The hysteresis in a comparator creates two trip points: one for the rising input voltage and one for the falling input voltage (Figure 1). The difference between the trip points is the hysteresis. When the comparator's input voltages are equal, the hysteresis effectively causes one comparator input voltage to move quickly past the other, thus taking the input out of the region where oscillation occurs. Standard comparators require hysteresis to be added with external resistors. The MAX941/MAX942/MAX944's www.maximintegrated.com Figure 1 illustrates the case where IN- is fixed and IN+ is varied. If the inputs were reversed, the figure would look the same, except the output would be inverted. The MAX941 includes an internal latch that allows storage of comparison results. The LATCH pin has a high input impedance. If LATCH is high, the latch is transparent (i.e., the comparator operates as though the latch is not present). The comparator's output state is stored when LATCH is pulled low. All timing constraints must be met when using the latch function (Figure 2). Shutdown Mode (MAX941 Only) The MAX941 shuts down when SHDN is low. When shut down, the supply current drops to less than 60A, and the three-state output becomes high impedance. The SHDN pin has a high input impedance. Connect SHDN to V+ for normal operation. Exit shutdown with LATCH high; otherwise, the output will be indeterminate. Input Stage Circuitry The MAX941/MAX942/MAX944 include internal protection circuitry that prevents damage to the precision input stage from large differential input voltages. This protection circuitry consists of two back-to-back diodes between IN+ and IN- as well as two 4.1k resistors (Figure 3). The diodes limit the differential voltage applied to the internal circuitry of the comparators to be no more than 2VF, where VF is the forward voltage drop of the diode (about 0.7V at +25C). For a large differential input voltage (exceeding 2VF), this protection circuitry increases the input bias current at IN+ (source) and IN- (sink). Input Current = (IN + - IN- ) - 2VF 2 x 4.1k Input current with large differential input voltages should not be confused with input bias current (IB). As long as the differential input voltage is less than 2VF, this input current is equal to IB. The protection circuitry also allows for the input common-mode range of the MAX941/MAX942/ MAX944 to extend beyond both power-supply rails. The output is in the correct logic state if one or both inputs are within the common-mode range.

MAX941 Timing Diagram with Latch Operator Output Stage Circuitry The MAX941/MAX942/MAX944 contain a current-driven output stage as shown in Figure 4. During an output transition, ISOURCE or ISINK is pushed or pulled to the output pin. The output source or sink current is high during the transition, creating a rapid slew rate. Once the output voltage reaches VOH or VOL, the source or sink current decreases to a small value, capable of maintaining the VOH or VOL static condition. This significant decrease in current conserves power after an output transition has occurred. One consequence of a current-driven output stage is a linear dependence between the slew rate and the load capacitance. A heavy capacitive load will slow down a voltage output transition. This can be useful in noisesensitive applications where fast edges may cause interference. Applications Information Circuit Layout and Bypassing The high gain bandwidth of the MAX941/MAX942/ MAX944 requires design precautions to realize the comparators' full high-speed capability. The recommended precautions are: 1) Use a printed circuit board with a good, unbroken, lowinductance ground plane. 2) Place a decoupling capacitor (a 0.1F ceramic capacitor is a good choice) as close to V+ as possible. 3) Pay close attention to the decoupling capacitor's bandwidth, keeping leads short. 4) On the inputs and outputs, keep lead lengths short to avoid unwanted parasitic feedback around the comparators. 5) Solder the device directly to the printed circuit board instead of using a socket. www.maximintegrated.com Maxim Integrated 8 MAX941/MAX942/ MAX944 IN+ 4.1k High-Speed, Low-Power, 3V/5V, Rail-to-Rail, Single-Supply Comparators TO INTERNAL CIRCUITRY MAX941 MAX942 MAX944 VCC MAX941 MAX942 MAX944 ISOURCE OUTPUT TO INTERNAL CIRCUITRY IN- 4.1k ISINK 0 Figure 3.
