1. General description

The 74AUP1G19 is a 1-to-2 decoder/demultiplexer with a common output enable. This device

buffers the data on input A and passes it to the outputs 1Y (true) and 2Y (complement) when the

enable (E) input signal is LOW. A HIGH E causes both outputs to assume a HIGH 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.
