SN74LS156N Description

Short technical summary and product information.

The SN74LS156N is a monolithic transistor-transistor-logic (TTL) circuit from Texas Instruments, featuring dual 1-line-to-4-line demultiplexers with individual strobes and common binary-address inputs in a single 16-pin package.

 

This component functions as a Decoder/Demultiplexer with a circuit configuration of 2 x 1:4. It operates with a single supply voltage ranging from 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C. The device consumes a maximum supply current of 10000µA.

 

Designed for applications such as Dual 2-to-4-Line Decoder, Dual 1-to-4-Line Demultiplexer, 3-to-8-Line Decoder, and 1-to-8-Line Demultiplexer, the SN74LS156N includes individual strobes that simplify cascading for decoding or demultiplexing larger words. Input clamping diodes are provided to minimize transmission-line effects and simplify system design. The outputs are open-collector.

 

The SN74LS156N is available in a 16-DIP (0.300", 7.62mm) package and is mounted via through-hole method.
