CD40103BNSR TI Counter Divider | 16-SO | 8-Bit, 3V-18V

Product Overview

The CD40103BNSR is a CMOS 8-bit synchronous down counter from Texas Instruments, designed for general-purpose counting and frequency division applications. It operates over a wide voltage range of 3V to 18V and is available in a 16-pin SO package. The device features a programmable divide-by-N counter with a single output (RCO) that goes low when the count reaches zero. It is ideal for use in timing circuits, frequency synthesizers, and industrial control systems.
