74HCT4520D-Q100J

Counter Dividers Overview

The Nexperia 74HCT4520D-Q100J is a dual 4-bit synchronous binary counter housed in an SO-16 (SOT109-1) package. It features two independent counters, each with buffered outputs (nQ0 to nQ3) and an asynchronous master reset input (nMR). The device supports dual clock inputs per counter: nCP0 triggers on LOW-to-HIGH transitions when nCP1 is HIGH, while nCP1 triggers on HIGH-to-LOW transitions when nCP0 is LOW. Operating within a supply voltage range of 4.5 V to 5.5 V, it meets AEC-Q100 Grade 1 qualification for automotive applications.

Counter Dividers Feature Summary

• Dual independent 4-bit synchronous counting capability with separate clock control
• Asynchronous master reset function that clears all outputs regardless of clock state
• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Input clamp diodes enabling interface to voltages exceeding the supply rail

Counter Dividers Applications

• Multistage synchronous counting systems
• Multistage asynchronous counting configurations
• Frequency divider circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range specifications. Confirm AEC-Q100 Grade 1 compliance status directly with the supplier or through official Nexperia channels prior to finalizing procurement orders.

Counter Dividers Selection Notes

Select this component for designs requiring dual independent 4-bit counters within a single integrated circuit. Ensure the system operates strictly within the 4.5 V to 5.5 V supply voltage limits defined for the HCT logic family. Verify that the required operating temperature range aligns with the specified -40 °C to +125 °C industrial grade.

Counter Dividers Part Context

This part belongs to the Nexperia 74HCT4520-Q100 series, which includes variants such as the 74HC4520D-Q100J. The series provides dual 4-bit synchronous binary counters designed for robust performance in demanding environments. The D suffix indicates the SO-16 plastic small outline package configuration.

Counter Dividers Replacement Considerations

The 74HC4520D-Q100J serves as a functional equivalent within the same series, differing primarily in input logic level compatibility rather than core counting functionality.
