CD4040BM

Counter Dividers Overview

The CD4040BM is a 12-stage binary ripple counter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports a maximum counting rate of 12 MHz. The device utilizes negative edge-triggered flip-flops for asynchronous reset functionality. It is housed in a 16-SOIC surface-mount package with an operating temperature range spanning from -55°C to +125°C.

Counter Dividers Feature Summary

• Provides 12-bit binary up-counting capability using negative edge-triggered logic stages.
• Features asynchronous reset control for immediate clearing of the count register.
• Supports wide supply voltage operation suitable for diverse digital logic environments.

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in instrumentation
• Timing and delay generation modules

Counter Dividers Procurement Notes

Verify the specific suffix 'BM' indicates the SOIC-16 surface mount package variant distinct from through-hole options. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability.

Counter Dividers Selection Notes

Select this component when a 12-bit binary counter is required in a surface-mount design. Compare against the CD4040BE (PDIP) or CD4040BPWR (TSSOP) if different packaging constraints apply. Verify that the 12 MHz maximum frequency meets the system clock requirements.

Counter Dividers Part Context

This part belongs to the Texas Instruments CD4000B series of CMOS logic devices. It functions as a core timing element within larger digital systems, often paired with decoders or buffers. The BM designation specifically identifies the small-outline integrated circuit package format used in modern PCB layouts.
