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 IOFF. The IOFF circuitry

disables the output, preventing a damaging backflow current through the device when it is powered

down.
