Procurement Notes

Verify the specific suffix J against official Nexperia documentation to confirm tape and reel packaging specifications. Ensure the procurement channel provides valid traceability records for AEC-Q100 compliance. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and avoid obsolete stock. Request updated datasheets to validate any recent design changes or pinout modifications.

Selection Notes

Select this component when designing circuits requiring multiple synchronized storage elements with independent reset controls. The HCT series compatibility ensures direct interfacing with TTL-level inputs while maintaining CMOS performance characteristics. Consider the TSSOP-20 package dimensions for PCB layout constraints. Verify that the operating voltage remains strictly within the 4.5 V to 5.5 V range to ensure reliable switching thresholds and timing parameters.

Part Context

This part is a member of the Nexperia 74HCT family, designed for high-speed operation with TTL-compatible input levels. The Q100 designation indicates automotive-grade reliability, subjecting the device to rigorous thermal and electrical stress testing. It serves as a fundamental building block for sequential logic circuits in safety-critical environments where long-term availability and consistent performance are mandatory.

Replacement Considerations

Public confirmed substitute part numbers: 74HC174PW-Q100J (HC series variant), 74HCT174D-Q100J (SOIC package variant). Verify pinout compatibility and electrical parameter equivalence before substitution.
