1. General description

The 74AUP2G240 provides the dual inverting buffer/line driver with 3-state output. The 3-state

output is controlled by the output enable input (nOE). A HIGH level at pin nOE causes the output 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 the input-disable feature, which allows floating input signals. The inputs are

disabled when the output enable input nOE is HIGH.
