CD74HCT40103M

Counter Dividers Overview

The CD74HCT40103M is an 8-bit synchronous binary down counter from the 74HCT series, manufactured by Harris Corporation. It features positive edge triggering and asynchronous reset capabilities. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum counting rate of 14 MHz. It is housed in a 16-pin SOIC package and functions across an industrial temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 8-bit binary down counting with positive edge clock triggering
• Asynchronous reset function for immediate initialization
• High-speed operation compatible with standard TTL logic levels

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division networks
• Event counting systems

Counter Dividers Procurement Notes

Verify manufacturer origin as Harris Corporation or authorized successor entities like Texas Instruments due to corporate acquisitions. Confirm RoHS compliance status and specific lot traceability requirements. Ensure the 16-SOIC package dimensions match design constraints. Validate that the HCT logic family compatibility meets system voltage and interface specifications before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component when a synchronous down counter with TTL-compatible inputs is required. The HCT series ensures compatibility with 5V CMOS logic families while offering higher speed than standard HC variants. Consider the 16-SOIC surface-mount package for automated assembly processes. Verify that the 14 MHz maximum frequency aligns with the application's clock requirements.

Counter Dividers Part Context

This part belongs to the widely used 74-series logic family, specifically the High-Speed CMOS (HC) variant adapted for TTL input levels (HCT). Originally produced by Harris Semiconductor, production rights and inventory were later managed by Texas Instruments following industry consolidations. The CD74HCT40103M represents a specialized configuration for precise downward counting operations in digital systems.

Counter Dividers Replacement Considerations

CD74HC40103M96: Pin-compatible alternative with HC logic levels instead of HCT. CD74HC40103MT: Surface-mount variant with HC characteristics. SN74HCT40103N: DIP package equivalent from Texas Instruments.
