74LVC3G07DP-Q100H

Overview

The Nexperia 74LVC3G07DP-Q100H is a triple non-inverting buffer with open-drain outputs, housed in an SOT505-2 (TSSOP8) 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, enabling direct interfacing with 5 V logic devices. The device features Schmitt trigger inputs for noise immunity and includes IOFF circuitry for partial power-down applications. Qualified to AEC-Q100 Grade 1 standards, it functions reliably from -40 °C to +125 °C.

Feature Summary

• Triple non-inverting buffers with open-drain outputs suitable for wired-OR/AND configurations
• IOFF circuitry prevents damaging backflow current during partial power-down states
• Schmitt trigger inputs provide tolerance for slower signal rise and fall times
• AEC-Q100 Grade 1 qualification ensures suitability for automotive environments

Applications

• Automotive engine control units
• Mixed 3.3 V and 5 V logic level translation
• Active-LOW wired-OR or active-HIGH wired-AND bus implementations

Procurement Notes

Verify the specific ordering suffix DP-Q100H corresponds to the TSSOP8 plastic thin shrink small outline package (SOT505-2). Confirm that the required temperature range aligns with the specified -40 °C to +125 °C operational limits. Ensure design compatibility with the open-drain output topology and necessary external pull-up resistors for proper high-level signaling.

Selection Notes

Select this component when three independent non-inverting buffers are required in a single package. The open-drain architecture is essential for implementing wired logic functions or interfacing with higher voltage domains than the supply rail. The inclusion of IOFF functionality makes it appropriate for systems requiring safe isolation during power-down sequences without external components.

Part Context

This part belongs to the Nexperia 74LVC3G07-Q100 family of automotive-grade logic buffers. It shares functional characteristics with other members of the series but differs in packaging; the DP variant utilizes the TSSOP8 form factor, whereas the DC variant uses VSSOP8. All variants maintain identical electrical specifications and AEC-Q100 Grade 1 qualification.

Replacement Considerations

The 74LVC3G07DC-Q100H serves as a pin-compatible alternative utilizing the VSSOP8 package. Verify mechanical footprint constraints before substitution, as the body width and lead dimensions differ between the TSSOP8 and VSSOP8 packages despite identical electrical performance.
