74HC257; 74HCT257

Quad 2-input multiplexer; 3-state

Rev. 7 — 2 February 2016

Product data sheet

1. General description

The 74HC257; 74HCT257 is a quad 2-input multiplexer with 3-state outputs. Inputs

include clamp diodes. This enables the use of current limiting resistors to interface inputs

to voltages in excess of V

2. Features and benefits



Non-inverting data path

3-state outputs interface directly with system bus

Complies with JEDEC standard no. 7A

Input levels:



For 74HC257: CMOS level



For 74HCT257: TTL level



ESD protection:



HBM JESD22-A114F exceeds 2000 V



MM JESD22-A115-A exceeds 200 V


