CD4018BM

Counter Dividers Overview

The CD4018BM is a CMOS presettable divide-by-N counter from the Texas Instruments 4000B series. It features a 5-bit synchronous up-counting architecture with positive edge triggering and asynchronous reset. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum counting rate of 8.5 MHz. It is housed in a 16-SOIC surface-mount package and functions reliably across an extended temperature range of -55°C to +125°C.

Counter Dividers Feature Summary

• Synchronous 5-bit Johnson counter with programmable external preset inputs for divide-by-N operation
• Positive edge-triggered clocking mechanism ensures precise state transitions
• Asynchronous reset capability allows immediate clearing of counter states independent of the clock signal

Counter Dividers Applications

• Frequency division circuits requiring specific integer ratios
• Digital timing sequences and pulse generation systems
• Programmable counters in industrial control logic

Counter Dividers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notifications regarding packaging or material updates. Ensure the 16-SOIC package variant matches design requirements before finalizing procurement orders.

Counter Dividers Selection Notes

Select this component for applications requiring robust CMOS logic with wide voltage tolerance. The 8.5 MHz speed rating suits moderate-frequency digital designs. Consider the 16-SOIC footprint for surface-mount assembly constraints. Evaluate thermal management needs given the -55°C to +125°C operational range for harsh environments.

Counter Dividers Part Context

Part of the Texas Instruments CD4000B family, which provides standard CMOS logic functionality. This specific model focuses on sequential logic operations, distinguishing itself from combinational gates by maintaining state through internal flip-flops. It serves as a foundational building block for complex digital counters and dividers.

Counter Dividers Replacement Considerations

CD4018BM96 is listed as a manufacturer-recommended alternative. MC14018BDG from onsemi is identified as a direct replacement option.
