The Texas Instruments SN74HC161PW is a versatile 4-bit synchronous binary counter designed for high-speed counting applications. It features internal carry look-ahead for efficient cascading in n-bit designs. The counter operates synchronously, with all flip-flops clocked simultaneously on the rising edge of the clock signal, eliminating output counting spikes.
This device supports a wide operating voltage range from 2V to 6V and offers a typical propagation delay of 14 ns, with a maximum count rate of 36 MHz. It features asynchronous clear functionality and synchronous presetting capabilities, allowing it to be set to any number between 0 and 15. The outputs can drive up to 10 LSTTL loads, and it consumes low power with a maximum Icc of 80 µA.
The SN74HC161PW is available in a 16-TSSOP surface mount package, making it suitable for various electronic designs. Its standard CMOS technology family ensures reliable performance in demanding applications.
