CD4518BEG4

Counter Dividers Overview

The CD4518BEG4 is a CMOS dual up-counter integrated circuit from the Texas Instruments 4000B series. It contains two independent synchronous decade counters, each capable of counting in the upward direction with four-bit binary-coded decimal (BCD) outputs. The device operates within a supply voltage range of 3V to 18V and supports a maximum clock frequency of 8MHz. It features asynchronous reset inputs for immediate clearing of the count registers. The component is housed in a 16-pin Plastic Dual In-Line Package (PDIP) designed for through-hole mounting. It functions reliably across an extended industrial temperature range of -55°C to +125°C.

Counter Dividers Feature Summary

• Dual independent synchronous decade counter architecture
• Up-counting operation with BCD output representation
• Asynchronous reset capability for immediate state clearing

Counter Dividers Applications

• Digital timing circuits requiring precise interval measurement
• Frequency division stages in signal processing systems
• Sequential control logic for automated machinery

Counter Dividers Procurement Notes

Verify the specific suffix 'G4' against current manufacturer documentation to confirm compliance with RoHS3 directives and lead-free specifications. Confirm package dimensions match the 16-PDIP standard before integration into existing footprints. Check for active status as legacy variants may have limited availability or require substitution with newer revisions.

Counter Dividers Selection Notes

Select this component when a design requires two separate synchronous counting channels within a single package. Ensure the operating environment stays within the specified -55°C to +125°C range. Verify that the input clock signal does not exceed the 8MHz limit at the chosen supply voltage. Consider the PDIP package constraints if board space is limited compared to surface-mount alternatives.

Counter Dividers Part Context

This part belongs to the CD4518B family of CMOS logic devices. It serves as a fundamental building block for digital arithmetic and timing applications. The device shares functional compatibility with other industry-standard dual decade counters but offers specific packaging and environmental ratings defined by the manufacturer's 4000B series guidelines.

Counter Dividers Replacement Considerations

The CD4518BE is listed as a manufacturer-recommended alternative. Verify pinout and electrical characteristics match before substitution.
