General description

The 74LVC1G19 is a 1-of-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.

Inputs can be driven from either 3.3 V or 5 V devices. These features allow the use of

these devices in a mixed 3.3 V and 5 V environment.

This device is fully specified for partial power-down applications using IOFF. The IOFF

circuitry disables the output, preventing the damaging backflow current through the device

when it is powered down.
