Counter Dividers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific suffix E4 indicates lead-free compliance as per manufacturer specifications. Ensure the TSSOP-16 package matches your PCB footprint requirements. Check current availability status as this specific part number may have discontinuation notices or be replaced by updated revisions in the CD40103B family.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous down counter with parallel load features is required. Ensure the design supports the 3 V to 18 V operating voltage range. Verify that the TSSOP-16 package dimensions fit the assembly constraints. Consider the -55 °C to +125 °C temperature rating for environmental suitability. Compare against standard asynchronous counters if synchronous clocking is necessary for system stability.

Counter Dividers Part Context

This device belongs to the CD4000B series of CMOS logic components produced by Texas Instruments. It serves as a specialized counter within the broader family of digital logic ICs designed for general-purpose computing and control applications. The BPW/E4 designation specifies the pinout, package type, and material composition relative to other variants in the CD40103B lineup.

Counter Dividers Replacement Considerations

The CD40103BPW is listed as a recommended substitute. Verify electrical compatibility and package equivalence before substitution. Consult official datasheets for both parts to ensure functional parity regarding pin assignments and timing characteristics.
