MC14518BDWG

Counter Dividers Overview

The MC14518BDWG is a dual BCD up counter manufactured by onsemi in a 16-pin SOIC-Wide package. It operates within a supply voltage range of 3.0 Vdc to 18.0 Vdc and supports an operating temperature range from -55°C to +125°C. The device contains two independent, internally synchronous 4-stage counters built with CMOS technology. Propagation delay times vary between 80 ns and 560 ns depending on the supply voltage and load conditions.

Counter Dividers Feature Summary

• Internally synchronous architecture designed for high internal and external speeds
• Logic edge-clocked design allowing incrementing on positive clock or negative enable transitions
• Diode protection provided on all input pins

Counter Dividers Applications

• Multi-stage synchronous counting applications
• Ripple counting applications requiring low power dissipation
• Circuits requiring high noise immunity

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DWG' corresponds to the SOIC-16 Wide (Pb-Free) package configuration. Confirm that the procurement channel provides official documentation supporting RoHS compliance and Pb-free status. Ensure the component meets the required automotive qualification standards if AEC-Q100 certification is necessary for the intended application environment.

Counter Dividers Selection Notes

Select this component when a dual BCD counter is required rather than a binary counter variant. Consider the wide supply voltage capability and extended temperature range for industrial environments. Verify that the asynchronous reset functionality and edge-clocking flexibility align with the system timing requirements.

Counter Dividers Part Context

This part belongs to the MC14518B series of dual up counters produced by onsemi. It utilizes complementary MOS P-channel and N-channel enhancement mode devices in a single monolithic structure. The device is distinct from the MC14520B, which serves as the dual binary counter counterpart within the same product family.
