CD74HC40103M

Counter Dividers Overview

The CD74HC40103M is an 8-bit binary down counter manufactured by Texas Instruments, belonging to the 74HC logic series. It features a single synchronous element with positive-edge triggered flip-flops and asynchronous reset capability. The device operates within a supply voltage range of 2 V to 6 V and supports counting rates up to 18 MHz. Designed for surface-mount installation, it utilizes a 16-SOIC package (0.154 inch width) and functions reliably across an extended industrial temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 8-bit binary down counting architecture
• Positive-edge triggered clock input mechanism
• Asynchronous reset functionality for immediate state clearing
• Wide operating voltage compatibility from 2 V to 6 V

Counter Dividers Applications

• Digital frequency division circuits
• Sequential control logic systems
• Timing sequence generation modules

Counter Dividers Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors due to end-of-life status. Confirm package integrity and pin alignment against the 16-SOIC specification. Validate RoHS compliance documentation prior to integration. Ensure storage conditions maintain moisture sensitivity level 1 standards to prevent soldering defects during assembly processes.

Counter Dividers Selection Notes

Select this component for applications requiring wide voltage operation and high-speed synchronous counting in compact surface-mount designs. Consider the 74HCT variant if strict 5 V logic level compatibility is required instead of the broader HC range. Evaluate thermal management requirements given the extended temperature rating and ensure PCB layout accommodates the specific SOIC footprint dimensions.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. It serves as a specialized counter within the broader portfolio of digital logic integrated circuits designed for general-purpose computing and control applications. The device complements other sequential logic components like shift registers and decoders in complex digital system architectures.
