GENERAL DESCRIPTION The MUX-08 is a monolithic eight-channei analog muliti- plexer which connects a single output to one of the eight analog inputs depending upon the state of a 3-bit binary address. The MUX-24 is a monolithic four-channel differential analog multiplexer configured in a double pole, four-position (plus OFF) electronic switch array. A two-bit binary input address connects a pair of independent analog inputs from each four-channel input section to the corresponding pair of independent analog outputs. All switches in the MUX-08/MUX-24 are turned OFF by applying logic 0 to the ENABLE pin, thereby providing a package select function. Fabricated with Precision Monolithics high performance Bipolar-JFET technology, these devices offer low, constant ON" resistance, low leakage currents and fast settling time 13-42 with low crosstalk to satisfy a wide variety of applications. These multiplexers do not suffer from latch-up or static charge blow-out problems associated with similar CMOS parts. The digital inputs are designed to operate from both TTL and CMOS levels while always providing a definite break-before-make action without the need for external pull- up resistors over the full operating temperature range. For single sixteen-channel and dual eight-channel modeis, refer to the MUX-16/MUX-28 data sheet.

The turn-off time is much faster than the turn-on time to guarantee this feature over the full operating temperature and input voltage range. Fabricated with Bipolar-JFET pro- cessing, special handling as required with CMOS devices, is not necessary to prevent damage to this multiplexer. Because the digital inputs only require a 2.0V logic 1 input level, power-consuming pull-up resistors are not required for TTL compatibility to insure break-make switching as is most often the case with CMOS multiplexers. The digital inputs utilize PNP input transistors where input current is maximum at the logic 0 level and drops to that of a reverse-biased diode (about 10nA) as the input voltage is raised above ~ 1.4V. The ON" resistance, Ron, of the analog switches is constant over the wide input voltage range of -15V to +11V with Vsupp.y = 15V. Higher input voltage is tolerable provided that some form of current limiting is employed (such as that of an op-amp output stage) to avoid exceeding junctior temperature and power dissipation requirements. Fornorma operation, however, positive input voltages should be restric- ted to 11V (or 4V less than the positive supply). This assures that the Veg of an OFF switch remains greater than its Vp and prevents that channel from being falsely turned ON When operating with negative input voltages, the gate-to channel diode will be turned on if the voltage drop acros an ON switch exceeds -0.6V. While this condition wi cause an error in the output, it will not damage the switch. | lab tests, the multiplexer output has been loaded with 0.01 uF capacitor in the circuit of Figure 1. With V;=-10Van Vg = +10V, the logic input was driven at a 1kHz rate. Th positive-going slew rate was 0.3V/us which is equivalent to normal Ipss of 3mA. The negative-going slew rate we 0.7V/us which is equivalent to a reverse Ipss of 7MA. Not that when switch 1 is first turned ON it has a drop of -20 across its terminals. In spite of that fact, the current is limite to approximately twice its normal Ipss. CROSSTALK AND OFF-ISOLATION Crosstalk and off-isolation performance is influenced f the type of package selected. Epoxy (P) packaged devicr typically exhibit a 12dB improvement in off-isolatic (f = 500kHz) performance when compared to ceramic ( packaged devices. Epoxy packaged devices typically exhit a 15dB improvement in crosstalk (f = 500kHz) performan: when compared to ceramic (Q) packaged devices.
