Description

General part information

SN74LVC257A-EP Series

The SN74LVC257A-EP quadruple 2-line to 1-line data selector/multiplexer is designed for 2.7-V to 3.6-V VCCoperation.

The device is 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 a high logic level.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.
