SN74HC393APW TI Counter IC | 14-TSSOP | Dual 4-bit Binary Counter

Product Overview

The SN74HC393APW from Texas Instruments is a high-speed dual 4-bit binary ripple counter fabricated using advanced silicon-gate CMOS technology. It contains two independent 4-bit binary counters, each with a clear and a clock input. The device operates over a wide voltage range of 2 V to 6 V and offers low power consumption typical of CMOS circuits, with high noise immunity and output drive capability comparable to LSTTL. The 14-pin TSSOP package is ideal for space-constrained applications.
