The SN74HC161PW is a high-speed synchronous 4-bit binary counter IC (Integrated Circuit) component. It is a member of the 74HC family of integrated circuits, which are CMOS (Complementary Metal-Oxide-Semiconductor) logic ICs.
The SN74HC161PW is designed to be used as a counter/frequency divider in various applications, including digital counters, frequency synthesizers, and clock generators. It is widely used in electronic projects, microcontrollers, and other digital systems requiring counting and division functions.
Key features of the SN74HC161PW include:
1. Synchronous Operation: All flip-flops in the IC are clocked simultaneously, ensuring accurate and reliable counting.
2. High-Speed Performance: The IC operates efficiently at high clock frequencies, making it suitable for applications that require fast counting operations.
3. Asynchronous Clear: The SN74HC161PW features an asynchronous clear input (CLR) that allows the counter to be reset to zero, regardless of the clock input. This feature provides flexibility in resetting the counter as needed.
4. 4-Bit Binary Counter: The IC consists of four flip-flops, each representing a bit in the binary counter. The outputs of these flip-flops provide the binary count values from 0000 to 1111 (0 to 15 decimal)
