CD74HCT4520E

Counter Dividers Overview

The CD74HCT4520E is a high-speed CMOS logic integrated circuit manufactured by Texas Instruments. It features two independent synchronous binary up-counters within a single package. The device utilizes HCT CMOS technology, ensuring compatibility with standard TTL logic levels while maintaining low power consumption characteristics typical of CMOS devices. It is designed for applications requiring reliable counting operations in digital systems.

Counter Dividers Feature Summary

• Contains two independent synchronous binary up-counter circuits
• Utilizes high-speed CMOS technology for efficient operation
• Provides direct clear functionality for resetting counter states

Counter Dividers Applications

• Digital frequency division circuits
• Time base generation for timing applications
• Event counting in digital measurement systems

Counter Dividers Procurement Notes

Verify the specific suffix 'E' indicates the PDIP-16 through-hole package variant when sourcing. Confirm that the component meets RoHS compliance requirements if restricted substances are a constraint for the assembly process. Ensure the supply chain source provides original manufacturer documentation to guarantee authenticity and traceability of the semiconductor batch.

Counter Dividers Selection Notes

Select this component when dual independent counters are required in a single footprint. The HCT series interface allows direct connection to TTL-driven systems without level shifting. Consider the PDIP-16 package for prototyping or applications requiring through-hole mounting on printed circuit boards where surface mount technology is not feasible.

Counter Dividers Part Context

This part belongs to the CD74HCT4520 family of dual binary counters. It shares functional similarities with other HCT series logic devices but is distinct in its counting architecture. The device is part of Texas Instruments' broader portfolio of high-speed CMOS logic solutions designed for industrial and commercial digital applications.

Counter Dividers Replacement Considerations

Direct pin-compatible substitutes may include other dual binary counters from the same HCT family, such as the CD74HC4520, noting potential differences in switching speed specifications. Verify voltage tolerance and propagation delay parameters against the original design requirements before substitution.
