CD40102BNSR TI Presettable BCD Down Counter | 16-SO | 3V-18V, 8MHz

Product Overview

The CD40102BNSR is a low-power, 8-stage presettable BCD down counter from Texas Instruments, fabricated with CMOS technology. It features a synchronous count-down capability, a preset input for loading initial count values, and a ripple-carry output for cascading multiple stages. The device operates over a wide voltage range of 3V to 18V, making it suitable for various industrial and consumer applications. Housed in a 16-pin SOIC package (16-SO), it offers a compact solution for frequency division, timing control, and event counting.
