74LVC2G241
Dual buffer/line driver; 3-state
Rev. 09 — 10 June 2008
Product data sheet
1. General description
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 of slower input rise and
fall times.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of the
74LVC2G241 as a translator 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 a damaging backflow current through the device
when it is powered down.
