CD4518BM

Counter Dividers Overview

The CD4518BM is a dual BCD up-counter integrated circuit from the Texas Instruments CD4000B series. It features two independent synchronous counters, each with four bits of capacity. The device operates on a supply voltage range of 3 V to 18 V and supports clock frequencies up to 8 MHz. It utilizes positive and negative trigger types for counting operations and includes asynchronous reset functionality. The component is housed in a 16-SOIC surface-mount package and is rated for an operating temperature range of -55°C to +125°C.

Counter Dividers Feature Summary

• Dual independent synchronous BCD up-counting capability within a single package
• Asynchronous reset function for immediate counter initialization
• Wide operating voltage range supporting diverse power supply environments
• Extended industrial temperature rating for reliable performance

Counter Dividers Applications

• Digital frequency division circuits
• Timekeeping and digital clock modules
• Event counting systems
• Sequential logic control applications

Counter Dividers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and environmental compliance. Ensure the source document explicitly identifies the part as the CD4518BM variant. Cross-reference datasheet revisions to confirm active status and pinout compatibility before integration into design specifications.

Counter Dividers Selection Notes

Select this component when dual independent BCD counting is required in a compact surface-mount form factor. The wide voltage tolerance allows flexibility in power design. Verify that the 16-SOIC footprint matches the PCB layout constraints and that the asynchronous reset requirement aligns with system control logic.

Counter Dividers Part Context
