1. General description

The 74AUP1G18 is a 1-to-2 demultiplexer with a 3-state outputs. The device buffers the data on

input A and passes it to output 1Y or 2Y, depending on whether the state of the select input (S) is

LOW or HIGH. The unused output assumes the high impedence OFF-state. Schmitt-trigger action

at all inputs makes the circuit tolerant of slower input rise and fall times. This device ensures very

low static and dynamic power consumption across the entire VCC range from 0.8 V to 3.6 V. This

device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables

the output, preventing the potentially damaging backflow current through the device when it is

powered down.
