CD4040BF

Counter Dividers Overview

The CD4040BF is a 12-bit asynchronous binary ripple counter manufactured by Texas Instruments. It operates within the 4000/14000/40000 series and utilizes negative edge triggering for counting in an up direction. The device is housed in a 16-lead hermetic ceramic dual-in-line package (CDIP). It supports a maximum operating frequency of 3.5 MHz at nominal supply voltage, with a load capacitance rating of 50 pF. The component functions as a single binary counter element.

Counter Dividers Feature Summary

• Asynchronous 12-bit binary ripple counter architecture
• Negative edge triggered clock input mechanism
• Hermetically sealed ceramic dual-in-line packaging

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting applications requiring high reliability
• Military and defense electronic systems

Counter Dividers Procurement Notes

Verify that the specific part number CD4040BF corresponds to the hermetic ceramic package variant rather than plastic or surface-mount options. Confirm RoHS compliance status, as this specific suffix indicates non-RoHS construction according to manufacturer documentation. Ensure the supplier provides traceability data suitable for military or aerospace qualification requirements associated with hermetic sealing.

Counter Dividers Selection Notes

Select this component when hermetic sealing is required for environmental protection in harsh conditions. The CDIP package offers superior radiation hardness compared to plastic variants. Consider the 3.5 MHz frequency limit when designing high-speed digital counters. Verify that the negative edge trigger logic aligns with the system clock polarity requirements.

Counter Dividers Part Context

This device belongs to the CD4000B series of CMOS logic integrated circuits. It shares functional similarities with other binary counters like the CD4020B but provides twelve output stages instead of fewer bits. The BF suffix specifically denotes the hermetic ceramic dual-in-line package option available from Texas Instruments for specialized industrial and military applications.

Counter Dividers Replacement Considerations

CD4040BF.A serves as a direct equivalent variant within the same hermetic ceramic package family.
