74LVC257A
Quad 2-input multiplexer with 5 V tolerant inputs/outputs;
3-state
Rev. 8 — 31 August 2021
Product data sheet
1. General description
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 IOFF. The IOFF circuitry
disables the output, preventing the potentially damaging backflow current through the device when
it is powered down.
