The SNJ54HC161FK from Texas Instruments is a 4-bit synchronous, presettable binary counter designed for high-speed counting applications. It features an internal carry look-ahead for enhanced performance.
This device operates over a wide voltage range of 2 V to 6 V, making it versatile for various power supply requirements. Its synchronous operation ensures that all flip-flops change coincidentally, eliminating output counting spikes common in ripple-clock counters. The buffered clock input triggers on the rising edge of the clock waveform.
Key electrical characteristics include a typical propagation delay of 14 ns, ±4 mA output drive at 5 V, and low power consumption with a maximum ICC of 80 µA. The low input current of 1 µA maximum further contributes to its efficiency.
The SNJ54HC161FK is available in the FK package, suitable for surface mount applications. Its design supports n-bit cascading through a carry output, enabling more complex counting configurations.
