SN74LVTH574PWRG4

Flip Flops Overview

The SN74LVTH574PWRG4 is an octal edge-triggered D-type flip-flop from the Texas Instruments LVTH series, housed in a TSSOP-20 package. It features TTL-compatible inputs and three-state outputs with non-inverting polarity. The device operates within a supply voltage range of 2.7 V to 3.6 V. Key electrical parameters include a propagation delay of 3 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It supports surface-mount installation and functions across a temperature range starting at -40°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• TTL-compatible input structure ensuring compatibility with standard logic families
• Three-state outputs allowing direct bus-driven connections without external buffers
• High drive capability supporting significant load currents for robust signal integrity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register files in microprocessor-based systems
• Buffering and latching operations on system buses
• Timing synchronization in digital communication interfaces

Flip Flops Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's 3.3 V power rail specifications. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement.

Flip Flops Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed performance in a 3.3 V environment. The LVTH series offers faster switching speeds compared to standard HC logic while maintaining lower power consumption than older ABT variants. Consider the TSSOP-20 package for space-constrained designs requiring surface-mount technology. Evaluate the high output drive strength if driving multiple loads or long traces.

Flip Flops Part Context

This part belongs to the SN74LVTH574 family of octal D-type flip-flops. It shares functional similarities with the SN74LVTH574PW but includes the G4 suffix denoting specific environmental compliance attributes. It differs from the SN74HC574 by offering TTL-compatible inputs and higher speed, and from the SN74HCT574 by operating at lower voltages with superior drive capabilities.

Flip Flops Replacement Considerations

The SN74LVTH574PW is a direct functional equivalent in the same package family. For RoHS-compliant alternatives, verify availability of the SN74LVTH574PWR variant. Cross-reference with SN74LVC574 devices if lower voltage operation is needed, noting differences in input compatibility and drive strength.
