QS74FCT16374TPA

Flip Flops Overview

The QS74FCT16374TPA is a 16-bit D-type flip-flop from the FCT series, manufactured by Quality Semiconductor. It features 3-state outputs and operates on a single 5V supply voltage. The device is housed in a 48-pin TSSOP plastic package with a shrink pitch. It supports an operating temperature range from -40°C to 85°C and has a typical propagation delay of 10 ns at nominal supply with 50 pF load capacitance.

Flip Flops Feature Summary

• Contains sixteen independent D-type flip-flops with positive-edge triggering.
• Provides three-state outputs for efficient bus-oriented memory and line driving applications.
• Compatible with standard CMOS logic levels for input signals.

Flip Flops Applications

• Bus-oriented memory register implementations
• Line driving circuits requiring high-speed data latching
• Parallel-to-serial data conversion modules

Flip Flops Procurement Notes

Verify the specific suffix 'TPA' against official Quality Semiconductor documentation to confirm pinout and electrical characteristics. Ensure the component meets required RoHS compliance status for the target application, as historical data indicates non-compliance for some variants in this series. Confirm package integrity upon receipt.

Flip Flops Selection Notes

Select this component when designing systems requiring 16-bit parallel data storage with high-speed performance. The FCT technology offers faster switching speeds compared to standard 74HC series devices. Consider the 48-pin TSSOP package constraints for PCB layout and thermal management during the design phase.

Flip Flops Part Context

This part belongs to the FCT (Fast CMOS) family, which bridges the speed gap between Schottky TTL and standard CMOS logic. Quality Semiconductor produced these components before industry consolidations. The 16374 designation specifically identifies a 16-bit latch/flip-flop configuration within the broader logic IC portfolio.

Flip Flops Replacement Considerations

Cross-reference with IDT or Renesas equivalents such as the IDT74FCT16374 series. Verify that substitute parts maintain identical pin configurations and electrical specifications, particularly the 5V operation and 3-state output behavior, to ensure circuit compatibility.
