MC14018BD

Counter Dividers Overview

The MC14018BD is a presettable divide-by-N counter manufactured by onsemi in a 16-pin SOIC package. It contains five Johnson counter stages that are asynchronously presettable and resettable. The device operates synchronously, incrementing on the positive clock edge. Division ratios from 2 to 10 are achieved via Jam inputs. Electrical specifications include a supply voltage range of -0.5 V to +18.0 V, an operating temperature range of -55°C to +125°C, and propagation delays ranging from 72 ns to 620 ns depending on load capacitance.

Counter Dividers Feature Summary

• Contains five Johnson counter stages with asynchronous preset and reset capabilities
• Features Schmitt trigger on the clock input for noise immunity
• Includes anti-lock gating to ensure proper counting sequences
• Capable of driving low-power TTL loads across the rated temperature range

Counter Dividers Applications

• Frequency division circuits
• Digital counters
• Timing control systems

Counter Dividers Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package configuration required for the design. Confirm RoHS compliance status if environmental regulations apply, as standard versions may differ from Pb-Free variants. Ensure the ordering information matches the exact shipping unit quantity specified for bulk procurement.

Counter Dividers Selection Notes

Select this component when a synchronous divide-by-N counter with asynchronous control is required. Verify that the logic family compatibility meets system interface requirements. Check that the maximum supply voltage and current drive capabilities align with the connected circuit loads and power constraints.

Counter Dividers Part Context

This part belongs to the MC14018B series of CMOS logic integrated circuits. It serves as a functional equivalent to the CD4018B, allowing for pin-for-pin replacement in existing designs. The device is part of the broader 4000B series of high-voltage CMOS logic products.
