Latches Procurement Notes

Verify the specific package code corresponding to the 'Q' suffix (QSOP) against current manufacturer documentation. Confirm RoHS compliance status as datasheet references may vary by revision. Ensure the ordering code matches the required speed grade and package dimensions before procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state bus interfacing capabilities. Consider the FCT logic family for its compatibility with TTL levels and superior performance over older bipolar counterparts. Evaluate the QSOP package constraints regarding board space and thermal requirements relative to other available pinouts.

Latches Part Context

This part belongs to the PI74FCT373T series of octal transparent latches produced by Pericom Semiconductor Corporation, now part of Diodes Incorporated. The series includes variants with different speed grades and packaging options such as TSSOP, SSOP, SOIC, and QSOP. These components are engineered to replace faster, lower-power alternatives to traditional bipolar logic families.

Latches Replacement Considerations

Direct pin-compatible replacements include other members of the PI74FCT373T series with different speed grades or packages, such as PI74FCT373ATL or PI74FCT373ATS. Verify that any substitute maintains the same 20-pin configuration and electrical characteristics.
