SN74AS257N Description

Short technical summary and product information.

The SN74AS257N from Texas Instruments is a digital multiplexer designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. This component features 3-state outputs that do not load the data lines when the output-enable input is at a high logic level.

 

Key electrical specifications include an operating voltage range of 4.5V to 5.5V and an operating temperature range of 0°C to 70°C. It supports a single supply voltage and has a circuit configuration of 4 x 2:1 with one independent circuit.

 

This device is available in a 16-DIP (0.300", 7.62mm) package and is designed for through-hole mounting. The SN74AS257N is suitable for high-performance systems requiring bus interface capabilities from multiple sources.
