DESCRIPTION
74LVC2G08
The 74LVC2G08 is a high-performance, low-power,
low-voltage, Si-gate CMOS device and superior to most
advanced CMOS compatible TTL families.
Inputs can be driven from either 3.3 V or 5 V devices. This
feature allows the use of these devices as translators in a
mixed 3.3 V and 5 V environment.
This device is fully specified for partial power-down
applications using I
off
. The I
off
circuitry disables the output,
preventing the damaging backflow current through the
device when it is powered down.
The 74LVC2G08 provides the 2-input AND gate function.
