CD4040BPWRG4

Counter Dividers Overview

The CD4040BPWRG4 is a CMOS binary ripple counter manufactured by Texas Instruments, belonging to the 4000B logic family. It features a 12-bit asynchronous up-counter architecture with negative-edge clock triggering 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. It is housed in a 16-TSSOP surface-mount package and is rated for operation across an extended temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Provides a 12-bit asynchronous binary counting function with dedicated Q0 through Q12 outputs.

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation for digital clocks
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific suffix G4 confirms RoHS compliance and green manufacturing status as per Texas Instruments standards. Confirm the TSSOP-16 package dimensions match the design footprint requirements. Ensure the operating environment remains within the specified -55°C to +125°C thermal limits to maintain signal integrity and prevent latch-up conditions during high-frequency operation.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous count sequence is required without complex decoding logic. It serves as a direct replacement for standard CD4040 equivalents in legacy designs. Consider the 12 MHz maximum speed limit when designing for higher frequency applications where faster counters might be necessary.
