SN74ALS257ADR Description

Short technical summary and product information.

The SN74ALS257ADR from Texas Instruments is a digital multiplexer designed for bus-organized systems. It allows multiplexing signals from four 4-bit data sources to four output data lines.

 

This device features 3-state outputs that do not load the data lines when the output-enable (OE) input is at a high logic level. The operating voltage range is 4.5V to 5.5V, with a typical quiescent current of 2.6mA and a maximum of 24mA. The operating temperature range is specified from 0°C to 70°C.

 

The SN74ALS257ADR is available in a 16-SOIC package and is designed for surface mount applications. Its circuit configuration is 4 x 2:1, with one independent circuit.

 

This multiplexer is suitable for high-performance systems requiring bus interfacing from multiple sources.
