74F257 - Quadruple 2-Line To 1-Line Data Selectors/Multiplexers

Description

The ′F257 is designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems.

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