CD74HC4518E

Counter Dividers Overview

The CD74HC4518E is a high-speed CMOS dual BCD up counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports through-hole mounting in a DIP-16 package. The device features synchronous counting with positive edge triggering, providing two independent decade counters per unit. It functions reliably across an extended temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Dual independent BCD up counters integrated into a single package
• Synchronous operation utilizing positive edge clock triggering
• High-speed CMOS technology compatible with standard logic families

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific manufacturer source for the 'E' suffix variant, as datasheets may list it under Harris or other legacy entities. Confirm RoHS compliance status and ensure the DIP-16 through-hole package matches your PCB footprint requirements before ordering.

Counter Dividers Selection Notes

Select this component when dual synchronous decade counting is required in a compact form factor. Ensure the operating voltage remains between 2 V and 6 V. Consider the HC series speed characteristics against lower-power alternatives if power consumption is a critical constraint.

Counter Dividers Part Context

This part belongs to the CD74HC4518 family of logic ICs. It serves as a successor to older CD4000 series counters, offering improved switching speeds while maintaining similar functional pinouts. The device is widely used in industrial and consumer electronics requiring reliable binary-coded decimal counting.

Counter Dividers Replacement Considerations

The CD4518BE is a direct functional equivalent within the same logical family. Verify that the replacement supports the required voltage range and package type.
