SN54LS155AJ Description

Short technical summary and product information.

The Texas Instruments SN54LS155AJ is a monolithic transistor-transistor-logic (TTL) circuit featuring dual 1-line-to-4-line demultiplexers with individual strobes and common binary-address inputs. This component is designed for applications requiring dual 2-to-4-line decoding or dual 1-to-4-line demultiplexing. It can also be configured as a 3-to-8-line decoder or a 1-to-8-line demultiplexer without external gating due to an integrated inverter.

 

Key specifications include the LS technology family, a military operating temperature range of -55 to 125°C, and a maximum supply current of 10000 µA. The device offers individual strobes to simplify cascading for larger decoding or demultiplexing tasks and includes input clamping diodes to minimize transmission-line effects. Available in CDIP (J) and CFP (W) packages, both with 16 pins.

 

This component is suitable for various digital logic applications where precise data routing and decoding are necessary. Its design facilitates system simplification through features like input clamping diodes and individual strobes.
