CD4520BNSR

Counter Dividers Overview

The CD4520BNSR is a CMOS dual binary up-counter integrated circuit from the Texas Instruments CD4520B series. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. The device features two independent synchronous 4-bit counters in a 16-pin SOIC package. Each counter includes a clock input with Schmitt trigger functionality and allows for parallel load or clear operations. The component is designed for surface-mount installation and complies with RoHS standards.

Counter Dividers Feature Summary

• Dual independent synchronous 4-bit binary up-counters
• Clock inputs equipped with Schmitt trigger buffers
• Wide operating supply voltage range supporting low-power applications
• Industrial temperature rating for harsh environment reliability

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation systems
• Binary counting logic modules
• Synchronous data processing units

Counter Dividers Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Ensure the component meets required environmental certifications such as RoHS compliance. Confirm that the supplier provides valid traceability documentation for industrial-grade parts. Check for any recent product qualification notices regarding carrier tape changes. Validate that the received units match the specified SOIC-16 footprint dimensions.

Counter Dividers Selection Notes

Select this component when dual independent binary counting is required in a single package. The Schmitt trigger on the clock input helps mitigate noise sensitivity in digital environments. Consider the wide voltage range for compatibility with various logic families. Verify that the synchronous operation aligns with system timing requirements. Ensure the SOIC-16 package fits the available PCB real estate constraints.

Counter Dividers Part Context

This part belongs to the CD4520B family of CMOS logic devices. It serves as a successor to earlier binary counter designs, offering improved noise immunity through Schmitt triggers. The dual configuration reduces board space compared to using two separate single counters. It is commonly used in conjunction with other CD4000-series components for complex digital systems.

Counter Dividers Replacement Considerations

CD4520BNSRG4 is a verified equivalent variant with identical electrical characteristics and pinout.
