74LVC3G34DP-Q100H

Overview

The Nexperia 74LVC3G34DP-Q100H is a triple buffer from the 74LVC-Q100 logic family, housed in an 8-lead TSSOP (SOT505-2) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports input voltages up to 5.5 V. The device features Schmitt-trigger inputs for noise immunity and includes IOFF circuitry for partial power-down protection. It is qualified to AEC-Q100 Grade 1 standards with an operating temperature range of -40 °C to +125 °C.

Feature Summary

• AEC-Q100 Grade 1 qualification for automotive environments
• IOFF circuitry prevents backflow current during power-down
• Schmitt-trigger inputs ensure tolerance to slow signal transitions
• Direct interface capability with TTL logic levels

Applications

• Mixed 3.3 V and 5 V voltage domain translation
• Automotive electronic systems requiring Grade 1 reliability
• Partial power-down applications utilizing IOFF functionality

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official documentation to confirm packaging details, as standard datasheets may list bulk or reel options without explicitly defining the 'H' designation. Ensure the TSSOP8 package type matches the required footprint. Confirm that the AEC-Q100 Grade 1 qualification aligns with the target application's environmental stress requirements before finalizing procurement.

Selection Notes

Select this component when a non-inverting triple buffer is required for automotive-grade designs. The wide supply voltage range accommodates both low-power and standard logic interfaces. The inclusion of IOFF makes it suitable for systems requiring safe isolation during power-off states. Verify that the TSSOP8 package dimensions fit the available PCB space compared to alternative packages like VSSOP8.

Part Context

This part belongs to the 74LVC-Q100 series, which represents Nexperia's automotive-qualified LVC logic line. The 'DP' indicates the TSSOP8 package variant, while 'Q100' denotes AEC-Q100 compliance. It serves as a non-inverting buffer counterpart to other logic gates within the same family, providing signal buffering and level shifting capabilities for mixed-voltage digital circuits.

Replacement Considerations

The 74LVC3G34DC-Q100H is a verified substitute offering identical electrical specifications but utilizes a VSSOP8 package instead of TSSOP8.
