1. General description

The 74AUP2G241 provides 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 tolerant to slower input rise and fall times

across the entire VCC range from 0.8 V to 3.6 V.

This device ensures a very low static and dynamic power consumption across the entire VCC range

from 0.8 V to 3.6 V.

This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry

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

powered down.

This device has an input-disable feature, which allows floating input signals. The input 1A is

disabled when the output enable input 1OE is HIGH. The input 2A is disabled when the output

enable input 2OE is LOW.
