MC14518BCPG

Counter Dividers Overview

The MC14518BCPG is a dual BCD up-counter integrated circuit manufactured by onsemi. It contains two independent four-bit synchronous counters within a single 16-pin PDIP package. The device operates on a supply voltage range of 3 V to 18 V and supports clock frequencies up to 8 MHz. It features asynchronous reset functionality and accepts positive or negative edge-triggered inputs. The component is rated for an operating temperature range from -55°C to +125°C.

Counter Dividers Feature Summary

• Dual independent four-bit binary-coded decimal counting circuits
• Synchronous operation with selectable positive or negative edge triggering
• Asynchronous reset capability for immediate counter clearing
• Wide supply voltage tolerance supporting diverse power environments

Counter Dividers Applications

• Digital frequency division circuits
• Decimal counting systems in industrial control
• Time-base generation for digital clocks
• Event sequence tracking in automation equipment

Counter Dividers Procurement Notes

Verify the obsolete status of this part number before procurement, as it may no longer be in active production. Confirm that the 16-PDIP through-hole package matches your board design requirements. Ensure the supplier provides valid RoHS compliance documentation. Check for parameter-equivalent alternatives if new manufacturing is unavailable. Validate the specific suffix against official datasheets to confirm pinout compatibility.

Counter Dividers Selection Notes

Select this component when dual independent decade counting is required in a single package. The wide voltage range allows operation in both low-power and high-noise environments. The through-hole PDIP package facilitates prototyping and manual assembly. Verify that the 8 MHz maximum clock speed meets the system timing requirements. Consider the extended temperature range for harsh industrial applications.

Counter Dividers Part Context

This component belongs to the 4000B series of CMOS logic devices. It serves as a fundamental building block for sequential logic designs requiring decimal counting. The dual configuration reduces board space compared to using separate single counters. It is designed for general-purpose digital applications where reliable synchronous counting is essential.

Counter Dividers Replacement Considerations

The CD4518BE from Texas Instruments is documented as a parameter-equivalent substitute.
