The SNJ54LS191J from Texas Instruments is a 4-bit synchronous binary up/down counter. This logic IC features a single down/up count control line and a count enable control input. Synchronous operation ensures that all flip-flops are clocked simultaneously, eliminating output counting spikes.
Key specifications include a technology family of LS, bipolar input type, and push-pull output type. It boasts high-speed performance with a typical propagation delay (tpd) between 10-50 ns. The operating temperature range is -55 to 125 °C, suitable for military applications. The counter supports 8-4-2-1 BCD or binary counting modes and is asynchronously presettable with load control.
This device is cascadable for n-bit applications, offering flexibility in system design. It is available in multiple package options including CFP (16-pin), CDIP (16-pin), and LCCC (20-pin). The complexity is rated at 58 equivalent gates.
Designed for applications requiring precise counting and control, the SNJ54LS191J is a robust component for digital systems.
