CD4520BE

Counter Dividers Overview

The CD4520BE is a dual binary up-counter integrated circuit from the Harris Corporation 4000B series. It contains two independent 4-bit synchronous counters within a single 16-pin package. The device operates on a supply voltage range of 3 V to 18 V and supports an operating temperature range of -55°C to 125°C. It utilizes a 16-DIP (0.300 inch) through-hole package. Each counter features a clock input, a clear input, and four parallel data outputs for binary counting applications.

Counter Dividers Feature Summary

• Dual independent 4-bit binary up-counter architecture
• Synchronous operation with dedicated clock and clear inputs
• Wide supply voltage compatibility for diverse logic levels
• Extended industrial temperature rating for harsh environments

Counter Dividers Applications

• Digital frequency division circuits
• Binary sequence generation systems
• Time base counters in digital clocks
• Event counting modules in instrumentation

Counter Dividers Procurement Notes

Verify component authenticity as the CD4520BE is listed as obsolete by the manufacturer. Confirm the specific manufacturing date code and lot traceability upon receipt. Ensure the 16-DIP package dimensions match the required PCB footprint. Check for physical damage to pins before installation. Validate electrical parameters against the official datasheet specifications during incoming inspection.

Counter Dividers Selection Notes

Select this component when a dual-channel binary counting solution is required without external wiring complexity. The wide voltage range allows direct interfacing with various logic families. Consider the through-hole package requirement for prototyping or high-reliability mounting. Evaluate the synchronous nature of the counter against asynchronous alternatives for timing precision needs in the target application.

Counter Dividers Part Context

This part belongs to the Harris Corporation 4000B series of CMOS logic devices. The series is known for high noise immunity and low power consumption. The CD4520BE specifically addresses the need for multiple counting channels in a compact form factor. It serves as a fundamental building block for sequential logic designs requiring reliable binary accumulation.

Counter Dividers Replacement Considerations

Compatible substitutes include the CD4520B and CD4520BM. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same voltage and temperature requirements.
