CD4018BE

Counter Dividers Overview

The CD4018BE is a CMOS presettable divide-by-N counter from the Texas Instruments CD4000B series. It features a 5-bit synchronous up-counter architecture housed in a 16-pin PDIP package. The device operates on a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55°C to +125°C. It utilizes positive edge triggering for its flip-flops and includes asynchronous reset functionality. The logic type is classified as a divide-by-N counter, suitable for programmable counting applications with external connections.

Counter Dividers Feature Summary

• Synchronous 5-bit up-counting capability with positive edge triggering
• Presettable divide-by-N operation allowing programmable counting sequences
• Wide operating voltage range supporting 3 V to 18 V supply levels
• Industrial temperature rating extending from -55°C to +125°C

Counter Dividers Applications

• Programmable frequency division circuits
• Digital timing and sequencing systems
• Johnson counter configurations
• General-purpose binary counting applications

Counter Dividers Procurement Notes

Verify the specific suffix 'BE' corresponds to the PDIP-16 through-hole package variant when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as manufacturing statuses and packaging options may vary by region and production batch. Ensure the ordering part number matches the required package style and temperature grade.

Counter Dividers Selection Notes

Select the CD4018BE when a synchronous 5-bit counter with preset capabilities is required in a through-hole package. Compare against other CD4000B series counters like the CD4518BE if dual BCD counting is needed instead of single 5-bit divide-by-N functions. Consider the CD4018BM or CD4018BM96 variants if surface-mount SOIC packaging is preferred over the PDIP form factor while maintaining identical electrical characteristics.

Counter Dividers Part Context

The CD4018BE belongs to the Texas Instruments CD4000B family of CMOS logic devices. This series is characterized by high noise immunity and low power consumption compared to earlier TTL counterparts. The CD4018 specifically provides a versatile solution for applications requiring programmable modulus counting, differing from fixed-modulus counters by allowing external connection of preset inputs to define the count limit.

Counter Dividers Replacement Considerations

• CD4018BM (SOIC-16 Package)
• CD4018BM96 (SOIC-16 Tape & Reel)
• MC14018BDG (onsemi, DIP-16)
