The DM74LS191N from Texas Instruments is a synchronous, reversible, 4-bit up/down counter designed for digital logic applications. It operates synchronously, meaning all flip-flops are clocked simultaneously, eliminating output count spikes common in asynchronous counters.
Key electrical characteristics include a typical clock frequency of 25 MHz and an average propagation delay of 20 ns. The counter is fully programmable, allowing outputs to be preset to any desired level via the load input. This feature enables its use as modulo-N dividers.
The device features a single down/up count control line and a count enable control input. Two outputs are provided for cascading: ripple clock and maximum/minimum count. The DM74LS191N is available in a 16-lead PDIP package (N16E).
This counter is suitable for applications requiring precise counting and control, such as frequency division, digital signal processing, and control systems where synchronous operation is critical.
