Overview
The Texas Instruments CD4520BMG4 is a CMOS dual binary up-counter integrated circuit. It is part of the 4000B series and is designed for medium-speed operation. The device consists of two identical, internally synchronous 4-stage counters, each stage being a D-type flip-flop. These counters can be used in various configurations, including single-unit operation and cascaded ripple mode. The CD4520BMG4 is available in a 16-lead small-outline package (SOIC) and is suitable for a wide range of applications requiring binary counting and frequency division.
