SN54HCT257 - QUADRUPLE 2-LINE TO 1-LINE DATA SELECTORS/MULTIPLEXER

Datasheet Summary

Description

ordering information NC

The ’HCT257 devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems.

The 3-state outputs do not load the data lines when the output-enable (OE) input is at the high logic level.
