SN74HC161D TI Counter IC | 16-SOIC | 4-Bit Binary, Asynchronous Reset

Product Overview

The SN74HC161D 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, with an asynchronous master reset (MR) that clears the counter regardless of the clock state. The device also includes a carry look-ahead capability for cascading multiple counters without external gating. Packaged in a 16-pin SOIC (D) package, it operates over a wide voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications.
