DESCRIPTION
The 74LVC2G241 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 74LVC2G241 is a dual non-inverting buffer/line driver
with 3-state outputs. The 3-state outputs are controlled by
the output enable inputs 1OE and 2OE. A HIGH level at
pin 1OE causes output 1Y to assume a high-impedance
OFF-state. A LOW level at pin 2OE causes output 2Y to
assume a high-impedance OFF-state. Schmitt-trigger
action at all inputs makes the circuit highly tolerant for
slower input rise and fall times.
