Counter Dividers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with operating temperature ranges and supply voltage requirements before integration. Confirm RoHS compliance status through manufacturer documentation. Validate moisture sensitivity levels for surface mount assembly processes.

Counter Dividers Selection Notes

Select this component when dual independent BCD counting functionality is required in a compact surface-mount package. Consider the wide supply voltage range and CMOS technology for low-power designs. Verify that the asynchronous reset and edge-clocked features align with system timing requirements. Compare pinout and electrical characteristics against alternative logic families if interface compatibility is critical.

Counter Dividers Part Context

This part belongs to the MC14518B series of dual up counters from onsemi. It is part of the broader 4000B CMOS logic family, known for wide voltage operation and compatibility with various digital logic standards. The BDW suffix typically denotes a specific wide-body SOIC package variant offered by the manufacturer for surface-mount technology applications.

Counter Dividers Replacement Considerations

The MC14518BDWR2G serves as a verified reel-packaged substitute for the tube version. Other variants within the MC14518B family may offer different packaging options but maintain identical logical functionality. Verify package dimensions and pin configurations when substituting to ensure board layout compatibility.
