CD4518BPW

Counter Dividers Overview

The CD4518BPW is a CMOS dual BCD up-counter integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports clock frequencies up to 8 MHz. The device features two independent four-bit synchronous counters with asynchronous reset capabilities, housed in a 16-TSSOP surface-mount package. It functions reliably across an extended temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Dual independent four-bit binary-coded decimal (BCD) counting channels
• Synchronous operation with dedicated clock input for each counter
• Asynchronous reset functionality for immediate zeroing of count states
• Wide operating voltage range compatible with standard logic levels

Counter Dividers Applications

• Digital timing circuits requiring precise interval measurement
• Frequency division stages in signal processing systems
• Decimal display drivers for numeric readouts
• Sequential control logic in industrial automation equipment

Counter Dividers Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-16 surface mount package variant. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required package type and environmental specifications for the target application.

Counter Dividers Selection Notes

Select this component when dual independent BCD counting is required in a compact surface-mount form factor. Consider the wide voltage tolerance for applications with varying power supplies. Evaluate the synchronous nature against asynchronous alternatives if specific timing constraints exist. Verify thermal performance requirements against the specified operating temperature range.

Counter Dividers Part Context

This device belongs to the CD4000B series of CMOS logic components, known for high noise immunity and low power consumption. The CD4518 specifically provides dual decade counters, distinguishing it from single-counter variants like the CD4510. It serves as a fundamental building block for complex digital systems requiring sequential state management.

Counter Dividers Replacement Considerations

The CD4518BPWR is listed as a manufacturer-recommended alternative, differing primarily in tape-and-reel packaging rather than functional characteristics. Other pin-compatible options within the CD4518 family may be considered if package variations are acceptable.
