CD4520BCN

Counter Dividers Overview

The CD4520BCN is a dual binary up-counter integrated circuit manufactured by onsemi. It belongs to the 4000B series of CMOS logic devices and features two independent synchronous 4-bit counters within a single package. The component supports a supply voltage range of 3V to 18V and operates reliably across an extended temperature range from -55°C to +125°C. It utilizes a 16-pin Dual In-Line Package (DIP) for through-hole mounting, providing a robust solution for digital counting applications requiring wide voltage tolerance and high noise immunity typical of CMOS technology.

Counter Dividers Feature Summary

• Dual independent synchronous 4-bit binary up-counters
• Wide operating voltage range supporting 3V to 18V
• Extended industrial temperature capability from -55°C to +125°C
• Through-hole 16-pin DIP packaging

Counter Dividers Applications

• Digital frequency division circuits
• Timekeeping and clock generation systems
• Event counting in industrial control panels
• Address decoding in memory systems

Counter Dividers Procurement Notes

Verify the specific suffix 'BCN' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Confirm availability status as legacy components may have limited production runs or require substitution with newer equivalents. Ensure the supplier provides valid RoHS compliance documentation consistent with onsemi standards before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a design requires two separate 4-bit counters in a single through-hole package. It is suitable for environments demanding wide voltage flexibility and extreme temperature stability. Consider alternative packages if surface-mount space constraints exist, or verify if single-counter variants suffice to reduce bill of materials complexity.

Counter Dividers Part Context

This device is part of the extensive 4000B CMOS logic family, known for high noise immunity and low power consumption. The CD4520 variant specifically addresses designs needing multiple counter stages without consuming excessive board space. It serves as a fundamental building block for sequential logic circuits in consumer electronics and industrial instrumentation.

Counter Dividers Replacement Considerations

Direct replacements include the CD4520BP and CD4520BNSR. Verify pin compatibility and electrical specifications with Texas Instruments or other authorized manufacturers offering equivalent 4000B series dual binary counters.
