SN74LS393NE4 TI Counter IC | Dual 4-Bit Binary Counter | 0°C~70°C, 4.75V~5.25V

Product Overview

The SN74LS393NE4 is a dual 4-bit binary counter from Texas Instruments, designed for high-performance digital systems. It integrates two independent 4-bit binary counters in a single 14-pin DIP package, each with a clear function. The device operates over a wide temperature range of 0°C to 70°C and a supply voltage of 4.75V to 5.25V, making it suitable for industrial and commercial applications. Its low power consumption and high noise immunity are characteristic of the LS family.
