74HC4520PW-Q100J

Counter Dividers Overview

The 74HC4520PW-Q100J is a dual 4-bit internally synchronous binary counter manufactured by Nexperia under the NXP USA Inc. brand portfolio. It features two clock inputs (nCP0 and nCP1) allowing flexible clocking or enable configurations, buffered outputs for all four bit positions (nQ0 to nQ3), and an asynchronous master reset input (nMR). The device operates within a wide supply voltage range of 2.0 V to 6.0 V, ensuring compatibility with various logic families. It complies with JEDEC standards and offers high noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Counter Dividers Feature Summary

• Dual 4-bit internally synchronous binary counting architecture
• Flexible clocking via two independent clock inputs supporting clock enable functionality
• Asynchronous master reset input for immediate state initialization
• High noise immunity and robust latch-up protection compliant with automotive reliability standards

Counter Dividers Applications

• Multistage synchronous counting systems
• Frequency divider circuits
• Digital timing control applications

Counter Dividers Procurement Notes

Verify the manufacturer designation carefully, as the component is produced by Nexperia but often listed under NXP USA Inc. distribution channels. Confirm the AEC-Q100 qualification status for automotive deployment requirements. Ensure the TSSOP-14 package variant matches the design footprint. Cross-reference the specific suffix codes to confirm RoHS compliance and lead-free status before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when dual independent 4-bit counters are required in a single package to save board space. It is suitable for designs needing a wide operating voltage range between 2.0 V and 6.0 V. Consider this part for applications requiring high noise immunity and robust ESD protection. It serves as a direct replacement for standard 74HC4520 devices where automotive-grade reliability is mandated.

Counter Dividers Part Context

This device belongs to the Nexperia 74HC series of high-cmOS logic components, specifically designed for automotive and industrial applications. The -Q100 suffix indicates adherence to AEC-Q100 stress test qualifications. It is part of a broader family of synchronous logic devices offering scalable solutions for digital system design. The PW package denotes a thin-shrink small-outline package suitable for automated surface-mount assembly processes.

Counter Dividers Replacement Considerations

The 74HCT4520PW-Q100J is a compatible alternative within the same family, differing primarily in input logic levels which support TTL compatibility. Verify voltage level requirements before substitution. Other generic 74HC4520 equivalents may lack the specific AEC-Q100 automotive qualification required for regulated environments.
