The SN54HC161J from Texas Instruments is a synchronous, presettable 4-bit binary counter designed for high-speed counting applications. It features an internal carry look-ahead for efficient cascading in n-bit synchronous designs. The device operates with a wide supply voltage range of 2 V to 6 V and has a typical propagation delay of 14 ns.
Synchronous operation ensures that all flip-flops are clocked simultaneously, eliminating output counting spikes. The counter is fully programmable and can be preset to any number between 0 and 15. It features an asynchronous clear function for resetting all outputs to low. The SN54HC161J is housed in a 16-pin CDIP package and operates across a temperature range of -55°C to 125°C.
Key electrical characteristics include a low power consumption of 80 µA maximum Icc and a low input current of 1 µA maximum. The outputs can drive up to 10 LSTTL loads, with a typical output drive of ±4 mA at 5 V. This makes the SN54HC161J suitable for various digital logic and control applications requiring precise counting and synchronous operation.
