CD74HC4520MT

Counter Dividers Overview

The CD74HC4520MT is a high-speed CMOS logic component manufactured by Texas Instruments, classified as a dual binary up counter. It features two independent 4-bit counters within a single package, designed for synchronous counting operations in the positive direction. The device operates on a supply voltage range of 2 V to 6 V and utilizes an SOIC-16 surface-mount package. It supports both positive and negative edge triggering modes and functions reliably across an extended industrial temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Dual independent 4-bit binary counter architecture
• High-speed CMOS technology for low power consumption
• Flexible clocking with selectable positive or negative edge triggering
• Industrial temperature rating for harsh environments

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation
• Address decoding logic

Counter Dividers Procurement Notes

Verify the specific suffix 'MT' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the ordering part number matches the required pinout and electrical specifications precisely. Cross-reference the date code and lot traceability requirements with the supplier's certification documents before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a design requires two separate 4-bit counters in a compact surface-mount form factor. It is suitable for applications needing flexible trigger polarity options. Compare performance against standard TTL counterparts if voltage levels differ significantly. Verify that the 2 V to 6 V operating range aligns with the system's power supply constraints and noise immunity requirements.

Counter Dividers Part Context

This device belongs to the Texas Instruments HC (High-speed CMOS) logic family, which offers faster switching speeds compared to legacy 4000B series devices while maintaining CMOS power efficiency. The CD74HC4520 variant specifically provides dual counters, distinguishing it from single-counter models like the CD74HC4516. It serves as a digital building block for sequential logic designs requiring binary accumulation.

Counter Dividers Replacement Considerations

Compatible substitutes include the SN74HC4520 and SN74HCT4520. Verify logic voltage compatibility, as HCT variants require 5 V logic levels. Check pin-to-pin compatibility and ensure the replacement package type matches the existing PCB footprint.
