SNJ54LS191FK Description

Short technical summary and product information.

The SNJ54LS191FK from Texas Instruments is a synchronous, reversible up/down counter with a 4-bit binary count. This component utilizes LS technology and features a bipolar input type with push-pull outputs. It operates within a temperature range of -55 to 125°C and is rated for military applications.

 

Key features include synchronous operation, eliminating output counting spikes. It has a single down/up count control line, a count enable control input, and a ripple clock output for cascading. The counter is asynchronously presettable with load control and offers parallel outputs, making it cascadable for n-bit applications. Its high-speed operation with propagation delays between 10-50ns makes it suitable for various digital logic designs.

 

Available in LCCC (FK), CDIP (J), and CFP (W) packages, this counter is designed for surface mount applications. The SNJ54LS191FK is a versatile component for digital systems requiring precise counting and control functionalities.
