CD40103BD3

Counter Dividers Overview

The CD40103BD3 is an 8-bit binary counter integrated circuit manufactured by Harris Corporation. It belongs to the 4000/14000/40000 series of CMOS logic devices and operates in a synchronous mode with positive edge triggering. The component features a single functional element and counts in the up direction. It is housed in a 16-lead Ceramic Dual In-line Package (CDIP) with a metal-sealed cofired body. The device supports a maximum operating frequency of 2.5 MHz at nominal supply voltage and has a load capacitance specification of 50 pF. It functions within a temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous 8-bit binary counting architecture with positive edge clock triggering
• Up-counting direction capability for sequential digital state progression
• Robust ceramic dual in-line package construction suitable for high-reliability environments

Counter Dividers Applications

• Digital timing sequence generation
• Frequency division circuits
• Pulse counting systems

Counter Dividers Procurement Notes

Verify the manufacturer designation as Harris Corporation on the component marking. Confirm the package type is 16-CDIP and the suffix indicates the specific variant. Check for RoHS compliance status, as documentation indicates non-compliance. Ensure the operating temperature range meets system requirements of -55°C to 125°C. Validate authenticity through authorized distribution channels due to potential availability from multiple sources.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous binary counter is required for up-counting applications. The positive edge trigger characteristic must align with the system clock polarity. Consider the 2.5 MHz maximum frequency limit for signal integrity. The CDIP package is necessary for hermetic sealing requirements in harsh environments. Verify that the 50 pF load capacitance matches the downstream input requirements.

Counter Dividers Part Context

This part is part of the extensive 4000-series CMOS logic family produced by Harris Corporation. It serves as a fundamental building block for digital counters and dividers. The CDIP packaging distinguishes it from plastic DIP variants, offering enhanced environmental protection. It complements other Harris logic components like decoders and gates in complex digital designs.

Counter Dividers Replacement Considerations

Check for direct pin-compatible substitutes from Harris or other manufacturers offering equivalent 8-bit synchronous binary counters in CDIP packages. Verify electrical parameters such as maximum frequency and operating temperature ranges match the original specifications.
