SN74HC393DR TI Dual 4-Bit Binary Counter | 14-SOIC | 2V to 6V, 36MHz

Product Overview

The SN74HC393DR from Texas Instruments is a dual 4-bit binary ripple counter with independent clock inputs and clear functions. Each counter consists of four master-slave flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section. The device features a wide operating voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. Housed in a compact 14-SOIC package, it is ideal for space-constrained designs.
