SN74ALS193ANS TI Synchronous Up/Down Counter | 4-Bit, Binary, 20-SOIC

Product Overview

The SN74ALS193ANS is a 4-bit synchronous up/down binary counter from Texas Instruments, designed for high-speed counting applications. It features a fully independent clock circuit and a clear function that resets the counter to zero. The device operates from a 4.5V to 5.5V supply and is available in a 20-pin SOIC package. Its synchronous operation ensures reliable counting in noisy environments, making it ideal for industrial and automotive systems.
