CD40102BEX

Counter Dividers Overview

The CD40102BEX is an 8-bit synchronous decade counter belonging to the 4000/14000/40000 series. It operates in a down counting direction and utilizes positive edge triggering for clock synchronization. The device is constructed using CMOS technology and is housed in a ceramic DIP-16 package. It features a TCO output and resets to the maximum count state. The component supports a maximum operating frequency of 700,000 Hz at nominal supply voltage and functions within a temperature range of -55 °C to 125 °C.

Counter Dividers Feature Summary

• Synchronous operation with positive edge triggering ensures precise timing control during the counting sequence.
• Down counting capability allows for sequential decrement operations from the loaded initial value.
• Integrated reset function automatically returns the counter to its maximum count state upon activation.

Counter Dividers Applications

• Digital countdown timer circuits requiring precise step-wise reduction
• Frequency division stages in synchronous digital systems
• Control logic sequencing where downward progression is required

Counter Dividers Procurement Notes

Verify the specific suffix 'EX' against manufacturer documentation to confirm package material and thermal rating variations. Confirm RoHS compliance status as legacy Harris components may differ from current standards. Ensure the supplier provides traceability for the ceramic DIP-16 package type. Validate that the delivered units match the synchronous decade counter specification rather than binary variants.

Counter Dividers Selection Notes

Select this component when a synchronous down-counting mechanism is required over asynchronous alternatives. The CMOS construction offers low power consumption suitable for battery-operated or heat-sensitive environments. Verify that the 700 kHz maximum frequency meets the system clock requirements. Consider the ceramic package durability if the application involves harsh industrial conditions compared to plastic variants.

Counter Dividers Part Context

This part belongs to the extensive 4000 series of CMOS logic devices originally developed by Harris Semiconductor. These components are widely used in general-purpose digital electronics. The decade counter variant specifically handles base-10 counting sequences, distinguishing it from binary counters like the CD4020. The CD40102BEX represents the commercial-grade version of this logic family.

Counter Dividers Replacement Considerations

CD40102BF: Identical functional specifications but potentially different package material (plastic vs. ceramic). CD40102BFX: Similar functionality with potential minor manufacturing process differences. Verify pin compatibility and electrical characteristics before substitution.
