3 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.
