SN74LVC574AQPWREP

Flip Flops Overview

The SN74LVC574AQPWREP is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and features a propagation delay of 7.8 ns. The device provides high-level output current of -24 mA and low-level output current of 24 mA. It is housed in a 20-TSSOP package (0.173 inch width) and supports mixed-mode signal operation on all ports, allowing 5-V input/output voltage compatibility with 3.3-V systems.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops with positive edge triggering
• Three-state outputs enabling direct bus driving connections without additional interface hardware
• Mixed-mode signal operation supporting 5-V I/O voltage levels while operating at 3.3-V logic
• Controlled baseline design ensuring single assembly site and single fabrication location for reliability

Flip Flops Applications

• Military and aerospace systems requiring controlled baseline components
• High-speed data acquisition systems utilizing mixed-mode signal interfaces
• Bus-oriented memory register implementations
• Industrial control systems demanding robust logic performance across wide voltage ranges

Flip Flops Procurement Notes

Verify the complete part number including the AQPWREP suffix to ensure procurement of the specific military-grade variant with controlled baseline manufacturing. Confirm that the 20-TSSOP package dimensions match the PCB footprint requirements. Ensure that the 3.3-V to 5-V mixed-mode capability aligns with the system's I/O voltage specifications before finalizing the order.

Flip Flops Selection Notes

Select this component when a controlled baseline flip-flop is required for mission-critical applications. The SN74LVC574AQPWREP is suitable for designs needing 5-V tolerance on inputs while operating from lower voltage supplies. Consider the 20-TSSOP package size for space-constrained layouts. Verify that the 7.8 ns propagation delay meets the timing constraints of the target digital circuit.
