Nexperia USA Inc. 74LVC3G07DP-Q100H

Overview

74LVC3G07DP-Q100 from Nexperia is a triple non-inverting buffer IC with open-drain outputs, designed for level-shifting and wired-OR/AND logic in automotive systems. It operates from 1.65 V to 5.5 V, accepts 5 V-tolerant inputs, and features IOFF partial power-down protection. Its Schmitt-trigger inputs support slow-rising signals, and it is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) for engine control and body electronics.

For engineers reviewing the 74LVC3G07DP-Q100 datasheet, 74LVC3G07DP-Q100 pinout, 74LVC3G07DP-Q100 application, or 74LVC3G07DP-Q100 equivalent, key selection criteria include open-drain drive capability (−24 mA at VCC = 3.0 V), wide supply range, automotive temperature rating, and IOFF-enabled backflow prevention during power sequencing.

Technical Context

This device implements three independent non-inverting buffers, each with an open-drain output stage enabling wired-logic configurations. The IOFF circuit actively disables outputs when VCC = 0 V, blocking reverse current flow - critical for hot-swap and mixed-voltage domain isolation.

All inputs incorporate Schmitt-trigger thresholds (e.g., VIH = 0.7VCC at VCC = 5.5 V; VIL = 0.3VCC), ensuring noise immunity and reliable operation with slow or noisy signals. Input voltage tolerance up to 5.5 V allows direct interfacing with legacy 5 V TTL and CMOS logic without external level shifters.

FAQ

Can 74LVC3G07DP-Q100 be used with a 1.8 V supply and 5 V pull-up resistors?

Yes. The device supports VCC = 1.65 V to 5.5 V and has 5 V-tolerant inputs and open-drain outputs. With VCC = 1.8 V, inputs accept 0–5.5 V, and outputs can safely sink current from a 5 V pull-up. VOL remains ≤0.70 V at IO = 4 mA, ensuring valid LOW recognition by 5 V logic receivers.

What happens to the outputs during power-down (VCC = 0 V)?

When VCC = 0 V, the IOFF circuit activates, placing all three outputs in a high-impedance OFF-state with leakage ≤ ±2 μA. This prevents reverse current flow from external pull-ups or driven nets into the unpowered IC - protecting both the device and upstream circuitry during partial power sequencing.

Is the 74LVC3G07DP-Q100 pin-compatible with non-automotive 74LVC3G07 variants?

Yes, electrically and physically. The DP suffix denotes TSSOP8 (SOT505-2) packaging, matching standard 74LVC3G07DP. Pin numbering, function, and footprint are identical. However, only the -Q100 version is AEC-Q100 qualified and specified for −40 °C to +125 °C operation with enhanced reliability testing.

How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?

Schmitt-trigger inputs provide hysteresis (~0.3×VCC), meaning VIH and VIL thresholds differ significantly (e.g., VIH ≈ 1.7 V, VIL ≈ 0.7 V at VCC = 2.5 V). This prevents multiple toggles on slow or noisy edges, making the device robust against EMI, crosstalk, and mechanical switch bounce - critical in automotive wiring harness environments.
