SN74HC393PWR TI Counter IC | 14-TSSOP | Dual 4-bit Binary Counter

Product Overview

The SN74HC393PWR from Texas Instruments is a high-speed dual 4-bit binary counter with a clear function, fabricated using advanced silicon-gate CMOS technology. It operates over a wide voltage range of 2V to 6V and features low power consumption, making it ideal for battery-powered and portable applications. The device contains two independent 4-bit binary counters, each with a clock input and a clear input. The counters are triggered on the negative-going edge of the clock pulse, and the clear input is active-high. The SN74HC393PWR is offered in a compact 14-pin TSSOP package, suitable for space-constrained designs.
