CD4018BNSR

Counter Dividers Overview

The CD4018BNSR is a CMOS presettable divide-by-N counter manufactured by Texas Instruments. It features a 5-bit synchronous up-counter architecture housed in a 16-pin SOP package. The device operates within a supply voltage range of 3 V to 18 V and supports a minimum working temperature of -55°C and a maximum of +125°C. It utilizes positive-edge triggering for clock inputs and includes asynchronous reset functionality.

Counter Dividers Feature Summary

• Synchronous 5-bit up-counter design with programmable preset capabilities
• Positive-edge triggered clocking mechanism for reliable state transitions
• Asynchronous reset input for immediate initialization of the count sequence

Counter Dividers Applications

• Digital frequency division circuits
• Programmable timing sequences
• Presettable counting applications

Counter Dividers Procurement Notes

Verify the specific suffix 'NSR' corresponds to the SOP-16 surface-mount package and reel/cut-tape packaging format. Confirm RoHS compliance status through official datasheets or manufacturer documentation, as environmental declarations may vary by production batch. Ensure the component matches the CD4000B logic series specifications before integration.

Counter Dividers Selection Notes

Select this component when a single-chip solution for variable modulus counting is required. It is suitable for designs needing wide voltage operation and industrial temperature ranges. Consider the 5-bit limit for maximum count values and verify interface compatibility with existing logic families in the system architecture.

Counter Dividers Part Context

This part belongs to the Texas Instruments CD4000B series of CMOS digital logic integrated circuits. The CD4018B variant specifically provides divide-by-N functionality, distinguishing it from standard binary counters like the CD4017 or CD4020. It is designed for general-purpose digital applications requiring flexible counting ratios.
