CD40193BK3

Counter Dividers Overview

The CD40193BK3 is a synchronous, positive edge-triggered, 4-bit bidirectional binary counter from the Harris Corporation 4000/14000/40000 series. It utilizes CMOS technology and is housed in a ceramic DIP16 package (JESD-30 code R-GDIP-T16). The device supports separate up and down clock inputs with distinct terminal count outputs for both directions. It features load/preset input capabilities and operates within a temperature range of -55 °C to 125 °C. The maximum operating frequency is 2 MHz at nominal supply voltage, with a load capacitance specification of 50 pF.

Counter Dividers Feature Summary

• Synchronous operation with positive edge triggering for reliable counting sequences
• Bidirectional counting capability with dedicated separate clocks for up and down operations
• CMOS construction ensuring compatibility with standard logic families

Counter Dividers Applications

• Digital timing and sequencing circuits requiring precise interval control
• Frequency division applications in digital signal processing systems
• Binary counting tasks in industrial control equipment

Counter Dividers Procurement Notes

Verify the specific suffix BK3 indicates the ceramic flatpack or DIP variant as per manufacturer documentation, noting potential differences from plastic versions. Confirm RoHS non-compliance status if environmental regulations apply to the end product. Ensure the supplier provides original Harris Corporation documentation to validate the component's authenticity and radiation-hardened characteristics if applicable to the specific batch.

Counter Dividers Selection Notes

Select this component when a synchronous, bidirectional 4-bit counter is required for high-reliability environments. The ceramic packaging offers superior thermal stability compared to plastic equivalents. Consider the separate clock inputs for independent up/down control rather than using a single direction pin. Verify that the 2 MHz maximum frequency meets the system's timing requirements.

Counter Dividers Part Context

This part belongs to the Harris Corporation 4000/14000/40000 series of CMOS logic devices. The BK3 suffix typically denotes a specific package style, often ceramic, which may offer enhanced durability over standard plastic variants. It is functionally equivalent to other industry-standard 40193 counters but manufactured under Harris specifications.

Counter Dividers Replacement Considerations

CD40193BF: Plastic DIP version of the same logical function. CD40193BQ: Quad flatpack variant. Verify package dimensions and pinout compatibility before substitution.
