CD4520BE TI Counter IC | 16-PDIP | Dual 4-Stage Binary Counter

Product Overview

The CD4520BE is a dual 4-stage binary counter manufactured by Texas Instruments (TI) in a 16-pin PDIP package. Each counter consists of four master-slave flip-flops internally connected to provide a divide-by-2 and divide-by-8 counter. The device features a reset function and can be cascaded for higher counting applications. It operates over a wide voltage range of 3V to 18V, making it suitable for various digital systems.
