• ± 8-mA Output Drive at 1.8 V V
CC
This 1-of-2 decoder/demultiplexer is operational at 0.8-V to 2.7-V V
CC
, but is designed specifically for 1.65-V to
1.95-V V
CC
operation.
The SN74AUC1G19 is a 1-of-2 decoder/demultiplexer. This device buffers the data on input A and passes it to
the outputs Y
0
(true) and Y
1
(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 I
off
. The I
off
circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
