SN74HC393NSR TI Dual 4-Bit Binary Counter | 14-SO | 2V to 6V, 36MHz

Product Overview

The SN74HC393NSR from Texas Instruments is a dual 4-bit binary counter with asynchronous clear, housed in a 14-pin SO package. It operates over a wide voltage range of 2V to 6V and features a typical clock frequency of 36MHz. Each counter consists of four flip-flops connected in a ripple carry configuration, providing a divide-by-16 function. The device is ideal for frequency division, timing, and counting applications in various electronic systems.
