QS74FCT377CTSO

Flip Flops Overview

The QS74FCT377CTSO is an octal D-type flip-flop with enable, belonging to the FCT logic series manufactured by Quality Semiconductor. It features a single-ended input and output configuration in a non-inverting polarity. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports surface mount installation in a SOIC-20 package. It handles eight input and eight output lines, with a typical propagation delay of approximately 6.5 ns at 25°C under standard 5V operation. The component functions as a register element suitable for high-speed digital applications.

Flip Flops Procurement Notes

Verify manufacturer authenticity through official channels, as multiple vendors list this component. Confirm RoHS compliance status prior to procurement, as some sources indicate non-compliance. Check current availability and lead times directly with suppliers, noting that distribution status may vary by region. Ensure the specific suffix matches required packaging options such as bulk or cut tape.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with enable is required for FCT series compatibility. Consider the SOIC-20 package size for surface mount constraints. Evaluate the 6.5 ns propagation delay against system timing requirements. Verify operating temperature range suitability for the intended environment, typically spanning -40°C to +85°C.

Flip Flops Part Context

This part belongs to the broader FCT logic family, which provides fast CMOS technology compatible with TTL inputs. The QS74FCT377CTSO specifically serves as an octal register variant within this lineup. Similar parts include bus drivers like the QS74FCT373TS1B, though functional differences exist between flip-flops and drivers. The component represents a specialized solution for parallel data handling in legacy and modern mixed-signal designs.

Flip Flops Replacement Considerations

Cross-reference with CY74FCT377CTSO from Texas Instruments for pin-compatible alternatives. Verify electrical specifications and package dimensions match before substitution. Note that manufacturer-specific variations may affect performance characteristics despite identical part numbers.
