The SNJ54LS169BJ is a synchronous 4-bit up/down binary counter manufactured by Texas Instruments. This component belongs to the LS technology family and utilizes a bipolar input type with a push-pull output.
Key features include a high-speed operation with propagation delays between 10-50ns. The device is designed for a wide operating temperature range, from -55°C to 125°C, and carries a military rating. Its synchronous operation ensures that all flip-flops are clocked simultaneously, minimizing output counting spikes.
This counter is fully programmable, allowing outputs to be preset to either logic level. The internal carry look-ahead circuitry facilitates cascading counters for n-bit synchronous applications without additional gating. Both count enable inputs (ENP\, ENT\) must be low to initiate counting, and the direction of the count is controlled by the up/down input.
The SNJ54LS169BJ is available in various package types including LCCC (FK), CFP (W), and CDIP (J), all suitable for through-hole mounting.
