QS74FCT377TQ is listed in the Flip Flops range at ChipApex. The manufacturer field lists Quality Semiconductor. Its product description is D FLIP-FLOP, FCT SERIES, 8-BIT. Review the specifications below when checking this part for your BOM.
The QS74FCT377TQ is an octal D-type flip-flop with enable, belonging to the FCT logic series. It features eight edge-triggered D-type flip-flops with individual data inputs and a common buffered clock input. The device supports partial-power-down mode via Ioff circuitry, which disables outputs to prevent backflow current. It is designed for address and data synchronization applications.
Verify component authenticity and datasheet alignment due to potential manufacturer transitions. Confirm RoHS compliance status as records vary. Check for obsolescence or lifecycle changes. Ensure package markings match official specifications. Validate supply chain sources for Quality Semiconductor products.
Select this component for high-speed octal registration requiring partial-power-down capabilities. Compare output drive characteristics against system requirements. Verify compatibility with existing FCT logic families. Consider noise immunity and ESD protection levels for the application environment.
