SN74LVTH574PWR

Flip Flops Overview

The SN74LVTH574PWR is an octal D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a voltage range of 1.65 V to 3.6 V, supporting low-voltage CMOS logic standards. The device features high-speed performance with propagation delays as low as 2.8 ns at 3.3 V. It includes latch-up protection exceeding 100 mA per JESD 78 and offers ESD protection ratings up to 2000 V human-body model. The component is housed in a TSSOP-20 package, suitable for portable and battery-powered applications requiring efficient power management and compact form factors.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with independent 3-state output control
• Supports partial-power-down mode via Ioff circuitry to prevent backflow current
• High noise immunity and robust latch-up performance for reliable operation
• Compatible with mixed 1.8-V and 2.5-V to 3.6-V systems

Flip Flops Applications

• Clock buffer and register applications in mobile communications
• Data acquisition systems requiring isolated storage registers
• Portable equipment utilizing low-voltage power supplies
• Consumer electronics with space-constrained PCB layouts

Flip Flops Procurement Notes

Verify the specific ordering suffix (e.g., PWR) corresponds to the required TSSOP-20 package and tape-and-reel quantity. Confirm that the manufacturer's datasheet revision matches the design requirements for electrical characteristics. Ensure compatibility with the target voltage domain before integration into the final assembly.

Flip Flops Selection Notes

Select this component when an octal register with tri-state outputs is required in a small outline package. Consider the LVTH series for applications needing tolerance to higher input voltages while operating at lower supply voltages. Evaluate the trade-off between propagation delay and power consumption against other LVC or LVT variants based on system timing constraints.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74LVTHxx family of octal flip-flops. It shares architectural similarities with the SN74LVC1G74 but provides eight channels instead of one. The LVTH designation indicates enhanced input voltage tolerance compared to standard LVC devices, allowing interfacing with 5-V signals despite lower VCC operation.

Flip Flops Replacement Considerations

Direct pin-compatible substitutes include the SN74LVTH574PW from the same manufacturer. Other compatible options may involve checking the SN74LVC574 series if input voltage tolerance requirements are relaxed. Always verify electrical specifications and package dimensions before substituting.
