CD4040BPW

Counter Dividers Overview

The CD4040BPW is a CMOS binary ripple counter manufactured by Texas Instruments, belonging to the 4000B series. It features a 12-bit asynchronous up-counter architecture with negative-edge triggered flip-flops and an asynchronous reset input. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 12 MHz at 10 V. It is housed in a 16-pin TSSOP package and functions reliably across an extended industrial temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Provides a 12-stage binary counting sequence for digital timing applications
• Features asynchronous reset capability for immediate state initialization
• Supports high-speed operation with a 12 MHz clock rate

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in measurement systems
• Timing control logic in consumer electronics

Counter Dividers Procurement Notes

Verify that the specific part number suffix matches the required package type, as the base model may be available in other formats such as DIP or SOIC. Confirm RoHS compliance status and check for lead-free variants if environmental regulations apply to your assembly process. Ensure the supplier provides valid traceability documentation for the manufacturing lot.

Counter Dividers Selection Notes

Select this component when a 12-bit binary count is required in a compact surface-mount footprint. Compare against the CD4040BE for through-hole requirements or the CD4040BPWR for reel-based automated assembly needs. Consider the operating voltage limits and temperature range to ensure compatibility with the target system environment.

Counter Dividers Part Context

This integrated circuit is part of the standard CD4000B family of CMOS logic devices produced by Texas Instruments. It serves as a fundamental building block for sequential logic designs requiring multi-bit storage and counting capabilities without external microcontrollers.

Counter Dividers Replacement Considerations

Compatible alternatives include the CD4040BE (PDIP-16) and CD4040BPWR (TSSOP-16). Verify pinout compatibility before substitution.
