SN74HC161PW TI Counter IC | 16-TSSOP | 4-Bit Binary, Asynchronous Reset

Product Overview

The SN74HC161PW from Texas Instruments is a high-speed 4-bit binary counter with asynchronous reset, designed for use in a wide range of digital applications. It features a synchronous 4-bit binary counting operation, a direct clear (CLR) input for asynchronous reset, and a ripple-carry output for cascading multiple counters. The device operates over a wide supply voltage range of 2 V to 6 V, making it suitable for battery-powered and industrial systems. Packaged in a compact 16-TSSOP, it offers a space-saving solution for modern electronic designs.
