Description

This 1-of-2 decoder/demultiplexer is operational at 0.8-V to 2.7-V VCC, but is designed specifically for 1.65-V to 1.95-V VCC operation.

The SN74AUC1G19 is a 1-of-2 decoder/demultiplexer. This device buffers the data on input A and passes it to the outputs Y0 (true) and Y1 (complement) when the enable (E) input signal is low.

NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
