U74LVC1G19
CMOS IC
1-OF-2
DECODER/DEMULTIPLEXER
„
DESCRIPTION
The U74LVC1G19 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 and 2Y when the enable input signal is
LOW.
This device is fully specified for partial power-down applications
using Ioff. The Ioff circuitry disables the outputs, preventing the
damaging backflow current through the device when it is powered
down.
„
FEATURES
* Operate from 1.65V to 5.5V
* Inputs accept voltages to 5.5V
* Low power dissipation, ICC=10μA (Max)
* ±24mA output drive(VCC=3V)
