CD4518BE

Counter Dividers Overview

The CD4518BE is a dual BCD up counter integrated circuit manufactured by Texas Instruments. It belongs to the CD4000B logic series and utilizes CMOS technology. The device features two independent synchronous decade counters, each providing four-bit binary-coded decimal output. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. The component is housed in a 16-pin PDIP package designed for through-hole mounting.

Counter Dividers Feature Summary

• Contains two independent synchronous BCD up counters within a single package
• Operates on standard CMOS technology compatible with the CD4000B logic series
• Supports wide supply voltage operation ranging from 3 V to 18 V
• Designed for industrial-grade performance with extended temperature capabilities

Counter Dividers Applications

• Digital counting systems requiring dual decade counting functions
• Timekeeping circuits utilizing synchronous up-counting sequences
• Industrial control logic interfacing with wide voltage ranges

Counter Dividers Procurement Notes

Verify the specific manufacturer source when ordering, as RCA originally developed this part number before Texas Instruments acquired the semiconductor assets. Confirm RoHS compliance status directly with the supplier, as legacy specifications may vary depending on the production batch and current manufacturing standards applied by Texas Instruments.

Counter Dividers Selection Notes

Select the CD4518BE when dual independent BCD counters are required in a through-hole configuration. Ensure the design accommodates the synchronous counting architecture and the specified voltage range. Consider the PDIP-16 package dimensions for PCB layout compatibility. Verify that the application does not require parallel load or down-counting capabilities, which are not supported by this specific model.

Counter Dividers Part Context

This component is part of the extensive CD4000B family of CMOS logic devices produced by Texas Instruments. It serves as a direct successor to earlier RCA designs, maintaining pinout and functional compatibility while adhering to modern manufacturing standards. The device is widely recognized in industrial and commercial electronics for its reliability in synchronous counting applications.

Counter Dividers Replacement Considerations

The CD4518BEE4 is a verified equivalent variant offered by Texas Instruments. Other manufacturers produce functionally similar parts under different part numbers, but direct substitution requires verification of electrical characteristics and package compatibility.
