74LVC1G240

Single inverting buffer/line driver; 3-state

The 74LVC1G240 is a 1-bit inverting buffer/line driver with 3-state output. The device features an output enable OE. A HIGH on OE causes the output to assume a high-impedance OFF-state. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using I_OFF. The I_OFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
