74LVC257AD

Quad 2-input multiplexer with 5 V tolerant inputs/outputs; 3-state

The 74LVC257A is a quad 2-input multiplexer; 3-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.
