CD4520BD3

Counter Dividers Overview

The CD4520BD3 is a dual binary counter integrated circuit manufactured by Harris Corporation. It features two independent synchronous counters, each with four bits of capacity. The device operates within a supply voltage range of 3V to 18V and supports an operating temperature range from -55°C to 125°C. It utilizes a 16-CDIP package for through-hole mounting. The logic type is defined as a binary counter with an up-counting direction.

Counter Dividers Feature Summary

• Dual independent four-bit synchronous binary counting functionality
• Wide operational voltage tolerance supporting low to medium power systems
• Extended industrial temperature rating for harsh environment reliability

Counter Dividers Applications

• Digital frequency division circuits
• Synchronous event counting systems
• Timing sequence generation modules

Counter Dividers Procurement Notes

Verify component authenticity due to potential radiation-hardened variants in the CD4520 series. Confirm RoHS compliance status as older Harris manufacturing runs may not meet current environmental standards. Ensure the specific suffix BD3 matches the required ceramic DIP package specification for your assembly process.

Counter Dividers Selection Notes

Select this component when dual independent counting channels are required in a single package. The synchronous design ensures stable state transitions without ripple delays. Verify that the 16-pin ceramic DIP form factor fits the target PCB layout constraints and thermal management requirements.

Counter Dividers Part Context

This part belongs to the CD4000/14000/40000 series of CMOS logic devices produced by Harris Corporation. It serves as a fundamental building block for digital logic designs requiring reliable binary accumulation. The CD4520 variant specifically offers dual-channel capability compared to single-counter alternatives.

Counter Dividers Replacement Considerations

Compatible substitutes include the CD4520BE and generic equivalents like MC14520B or HEF4520B. Verify pin compatibility and electrical specifications before substitution.
