SN74LVTH574DW

Flip Flops Overview

The SN74LVTH574DW is an octal D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the LVTH logic series and features a non-inverting polarity with TTL input compatibility. 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 is housed in a 20-pin SOIC package designed for surface mount technology.

Flip Flops Feature Summary

• Provides eight independent edge-triggered D-type flip-flops with tri-state outputs for bus interface applications
• Features low-voltage CMOS technology compatible with 3.3-V systems while accepting TTL-level inputs
• Delivers high-speed performance with a 3 ns propagation delay for efficient data latching

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and register operations in communication systems
• I/O port expansion for microcontroller-based designs

Flip Flops Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel versus tube packaging configuration. Ensure the voltage supply requirements align with the 2.7 V to 3.6 V operational range specified in the datasheet. Confirm RoHS compliance status and check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring 3.3-V operation with high drive capability and fast switching speeds. The LVTH series offers superior performance compared to standard LVT devices due to its ABT-like structure. Consider the 20-SOIC package dimensions for PCB layout constraints and ensure thermal management meets the surface mount installation requirements for reliable long-term operation.

Flip Flops Part Context

This part is part of the SN74LVTH574 family of octal D-type flip-flops. It shares functional similarities with other 574-series devices but is optimized for lower voltage operation. The DW suffix indicates a 20-pin wide SOIC package. It serves as a bridge between older TTL-compatible designs and modern low-voltage logic standards.

Flip Flops Replacement Considerations

SN74LVTH574DWR is the reel version of the same device. SN74BCT574DW is a BCT series alternative operating at 5 V. SN74HC574DW is a HC series alternative with different speed and voltage characteristics.
