74ACT11257 - QUADRUPLE 2-LINE TO 1-LINE DATA SELECTOR/MULTIPLEXER

Description

The 74ACT11257 is designed to multiplex signals from 4-bit data sources to four 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 a high logic level.
