Counter Dividers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Confirm RoHS compliance status and check for End-of-Life notices or alternative part recommendations from onsemi before finalizing procurement decisions.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous 4-bit counting with low power consumption typical of HC logic. Ensure the operating voltage aligns with the 2 V to 6 V range and verify that the TSSOP package fits the board layout constraints.

Counter Dividers Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It serves as a fundamental building block for digital counters, offering compatibility with standard TTL levels while providing improved noise immunity and lower power dissipation compared to older logic families.

Counter Dividers Replacement Considerations

Check for direct pin-compatible alternatives such as MC74HC161ADR2G or other manufacturers' 74HC161 variants. Verify electrical characteristics and package dimensions match the original design requirements.
