CD74HCT393M TI Counter IC | 14-SOIC | Dual 4-bit Binary Ripple Counter

Product Overview

The CD74HCT393M from Texas Instruments is a high-speed CMOS dual 4-bit binary ripple counter fabricated with silicon gate technology. It features two independent counters in a single 14-pin SOIC package, each with a master reset input. The device operates over a wide voltage range of 4.5V to 5.5V and is compatible with TTL inputs, making it ideal for interfacing with legacy logic families. With a typical clock frequency of 25 MHz and low power consumption, the CD74HCT393M is suitable for frequency division, timing, and counting applications in industrial and consumer electronics.
