Counter Dividers Procurement Notes

Verify the specific suffix 'BDWR2G' against the official datasheet to confirm package dimensions and tape-and-reel specifications. Confirm that the AEC-Q100 qualification aligns with your target application's environmental requirements. Check current lifecycle status as automotive variants may have distinct obsolescence timelines compared to standard commercial parts.

Counter Dividers Selection Notes

Select this component when dual independent BCD counting is required within a single integrated circuit footprint. Ensure the input signal edges match the positive or negative trigger requirements specified in the logic diagram. Verify that the supply voltage remains within the 3 V to 18 V range to maintain switching speed and noise immunity characteristics defined for the 4000B series.

Counter Dividers Part Context

This part is the automotive-qualified variant of the MC14518B dual BCD counter. It shares the same logical function as the commercial MC14518BDWR2G but meets stricter automotive reliability standards. It belongs to the broader 4000B CMOS logic family, offering compatibility with other standard CMOS devices while providing enhanced durability for vehicle electronics.

Counter Dividers Replacement Considerations

MC14518BDWR2G serves as the direct commercial equivalent. Other compatible parts include MC14518BPWR2G and MC14518BDR2G, provided they meet the specific packaging and automotive qualification requirements of the design.
