CD4520BME4

Counter Dividers Overview

The CD4520BME4 is a CMOS dual binary up-counter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports synchronous counting sequences. The device features Schmitt trigger inputs on the clock lines for noise immunity and includes independent clear functions for each counter. Packaged in a 16-pin SOIC surface-mount format, it is designed for reliable operation across an extended temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary up-counters with synchronous operation
• Schmitt trigger clock inputs for enhanced noise rejection
• Independent asynchronous clear inputs for each counter section

Counter Dividers Applications

• Digital timing and frequency division circuits
• Event counting systems
• Sequential logic control applications

Counter Dividers Procurement Notes

Verify the complete part number including the suffix E4, which indicates lead-free status and RoHS compliance, against official Texas Instruments documentation. Confirm the package marking and pin configuration match the SOIC-16 specification. Ensure the source provides valid traceability for the manufacturing date code and lot information to guarantee component authenticity and quality standards.

Counter Dividers Selection Notes

Select this component when a dual-channel synchronous counting solution is required with high noise immunity due to Schmitt trigger inputs. It serves as a direct functional replacement for standard CD4520 devices where lead-free processing is mandated. Consider the wide operating voltage range and industrial temperature rating for robust performance in varying environmental conditions compared to lower-grade alternatives.

Counter Dividers Part Context

This component belongs to the Texas Instruments CD4000/CD4500 series of CMOS logic devices. The CD4520B variant specifically denotes the dual up-counter function within this family. The 'E4' suffix identifies the specific ordering code for the lead-free, RoHS-compliant version packaged in the SOIC-16 form factor, distinguishing it from other package options or non-compliant variants.

Counter Dividers Replacement Considerations

The CD4520BM is the non-lead-free equivalent. Cross-reference with MC14520B or HCC4520B for functional compatibility from other manufacturers, ensuring voltage and temperature specifications align.
