74AUP3G34DCH

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AUP3G34DCH is a low-power triple buffer in an 8-lead VSSOP (SOT765-1) package. It operates across a supply voltage range of 0.8 V to 3.6 V with Schmitt trigger inputs for noise immunity. The device features IOFF circuitry for partial power-down mode, preventing backflow current. Static supply current is limited to 0.9 μA maximum at -40 °C to +85 °C and 1.4 μA at -40 °C to +125 °C. Propagation delay ranges from 1.0 ns to 5.1 ns depending on load capacitance and voltage.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Schmitt trigger action provides tolerance for slow input rise and fall times
• IOFF circuitry enables partial power-down mode operation
• High noise immunity with low overshoot and undershoot characteristics

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down applications requiring backflow current prevention
• Signal buffering in systems with slow input transitions
• Low-voltage logic interface circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DCH corresponds to the VSSOP8 plastic very thin shrink small outline package (SOT765-1). Confirm the temperature range specification matches the required operational environment of -40 °C to +125 °C. Ensure compliance with JEDEC standards relevant to the target supply voltage range.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a triple non-inverting buffer with Schmitt triggers is required for low-voltage applications. The VSSOP8 package is suitable for space-constrained surface-mount designs. Consider the IOFF feature if the system requires protection against damaging currents during power-down states.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AUP series of low-power CMOS logic devices. The 74AUP3G34DCH specifically denotes the triple buffer variant housed in the SOT765-1 VSSOP8 package. It shares functional characteristics with other packages in the family, such as XSON variants, but differs in physical dimensions and thermal dissipation capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Other packages within the same logical family, such as 74AUP3G34GT or 74AUP3G34GN, offer identical electrical performance. Substitution requires verifying pin compatibility and ensuring the alternative package fits the available board space.
