CD40103BEG4

Counter Dividers Overview

The CD40103BEG4 is an 8-stage binary down-counter integrated circuit belonging to the Texas Instruments CD4000B logic family. It features synchronous operation with a dedicated clock input and supports asynchronous preset and reset functions for flexible state control. The device operates within a supply voltage range of 3 V to 18 V, ensuring compatibility across various standard digital logic levels. It utilizes a 16-pin Plastic Dual In-Line Package (PDIP) designed for through-hole mounting on printed circuit boards. The component is rated for extended industrial temperature ranges, supporting reliable performance in demanding environments.

Counter Dividers Feature Summary

• Synchronous 8-bit binary counting architecture with independent clock input
• Asynchronous parallel preset capability for direct data loading
• Asynchronous master reset function for immediate zeroing
• Wide operating voltage range compatible with multiple logic standards

Counter Dividers Applications

Counter Dividers Procurement Notes

Verify the specific EG4 suffix indicates lead-free construction compliant with RoHS directives. Confirm package dimensions match the target PCB footprint requirements. Ensure supply chain sources provide original manufacturer documentation to validate authenticity. Check for any recent product lifecycle notices regarding availability status.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous down-counter is required with parallel load functionality. Consider the wide voltage tolerance for designs needing flexibility between low and high power rails. Evaluate the PDIP package constraints against available board space and assembly methods. Compare propagation delays against system timing requirements at the intended operating voltage.

Counter Dividers Part Context

This part belongs to the CD4000B series, representing second-generation CMOS logic technology from Texas Instruments. The series offers improved noise immunity and lower power consumption compared to earlier iterations. The EG4 designation specifically identifies the lead-free variant manufactured under environmental compliance standards. This family remains widely used in general-purpose digital logic applications requiring robust performance.

Counter Dividers Replacement Considerations

CD40103BE serves as the standard non-rohs equivalent. CD40102BNSR provides similar counting capabilities but differs in package type and pinout configuration.
