SN74ALS258A - Quad 2-Line To 1-Line Data Selectors/Multiplexers

Download the SN74ALS258A datasheet PDF. This datasheet also covers the SN74AS257 variant, as both devices belong to the same quad 2-line to 1-line data selectors/multiplexers family and are provided as variant models within a single manufacturer datasheet.

Description

These data selectors/multiplexers 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 a high logic level.
