Nexperia USA Inc. 74AUP3G07GSX

Overview

74AUP3G07GSX from Nexperia is a triple non-inverting buffer IC with open-drain outputs, Schmitt-trigger inputs, and IOFF partial power-down capability. It operates across 0.8 V to 3.6 V supply, delivers ≤0.9 μA max ICC at 125 °C, supports wired-OR/AND logic sharing, and is qualified for −40 °C to +125 °C ambient. It enables level-shifting I²C bus extensions and low-power sensor interface buffering in space-constrained portable electronics.

For engineers reviewing the 74AUP3G07GSX datasheet, 74AUP3G07GSX pinout, 74AUP3G07GSX application, or 74AUP3G07GSX equivalent, key selection criteria include open-drain drive strength at 3.0 V (VOL ≤ 0.50 V @ 4 mA), input hysteresis tolerance for slow-rising signals, IOFF-enabled backflow prevention during partial power-down, and XSON8 package thermal derating behavior above 81 °C.

Technical Context

This device implements three independent non-inverting buffers, each with Schmitt-trigger input thresholds (VIH ≥ 0.70×VCC, VIL ≤ 0.25×VCC at 125 °C) and open-drain NMOS output stages. The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA even with VI/VO biased up to 3.6 V.

Propagation delay ranges from 1.1 ns (VCC = 3.0 V, CL = 5 pF) to 11.4 ns (VCC = 3.0 V, CL = 30 pF), with CPD = 1.2 pF enabling dynamic power calculation via PD = CPD × VCC² × fi × N. Input capacitance is 0.7 pF and output capacitance is 0.9 pF, supporting high-speed signal integrity in low-capacitance PCB layouts.

FAQ

What is the maximum sink current capability of each 74AUP3G07GSX output?

Each open-drain output can sink up to 20 mA continuously, verified across −40 °C to +125 °C and 0.8 V to 3.6 V VCC. At 3.0 V supply and 4 mA load, VOL remains ≤0.50 V - sufficient to drive standard 10 kΩ pull-ups on I²C buses while maintaining noise margin.

Does 74AUP3G07GSX support level translation between different VCC domains?

Yes - inputs accept voltages up to 3.6 V regardless of VCC (e.g., 1.2 V supply with 3.3 V input signal), and outputs are open-drain, allowing external pull-up to any higher voltage rail (e.g., 5 V). This enables bidirectional level shifting without direction control logic.

How does the IOFF feature behave when VCC is ramping during power-up?

IOFF activates when VCC falls below ~0.2 V and remains active until VCC exceeds ~0.6 V. During this window, output leakage is limited to ±0.75 μA even if input/output pins are biased to 3.6 V - preventing latch-up or damage in asymmetric power sequencing scenarios.

Can multiple 74AUP3G07GSX outputs be safely tied together on a single bus line?

Yes - all three outputs are true open-drain with no internal clamping diodes to VCC or GND. When paralleled, they implement a wired-AND function: the bus goes LOW only if ≥1 output is actively sinking. Total sink current sums linearly (up to 60 mA), provided trace and pull-up design accommodate combined loading.
