Nexperia USA Inc. 74AUP3G07GNX

Overview

74AUP3G07GNX 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 industrial and extended temperature operation (–40 °C to +125 °C) in XSON8 package.

For engineers reviewing the 74AUP3G07GNX datasheet, 74AUP3G07GNX pinout, 74AUP3G07GNX application, or 74AUP3G07GNX equivalent, key selection criteria include open-drain drive strength at low VCC, Schmitt-trigger noise immunity across voltage scaling, IOFF-enabled system-level power sequencing, and compatibility with 1.2 V, 1.8 V, and 3.3 V I/O domains.

Technical Context

The device implements three independent non-inverting buffers, each with an open-drain output stage enabling wired-logic connections without external pull-ups in active-LOW wired-OR or active-HIGH wired-AND configurations. All inputs feature Schmitt-trigger action, ensuring robust signal integrity with slow-rising/falling edges across the full 0.8 V–3.6 V VCC range.

IOFF circuitry actively disables outputs during power-down, blocking backflow current when VCC = 0 V while inputs/outputs remain biased up to 3.6 V. Static power consumption remains below 1.4 μA (max) over –40 °C to +125 °C, and dynamic propagation delay ranges from 1.1 ns (VCC = 3.3 V, CL = 5 pF) to 11.4 ns (VCC = 0.8 V, CL = 30 pF).

FAQ

Can 74AUP3G07GNX drive a 10 kΩ pull-up resistor at 3.3 V while maintaining VOL ≤ 0.4 V?

Yes. At VCC = 3.3 V and IO = 3.1 mA, the datasheet specifies VOL ≤ 0.36 V (max) over –40 °C to +125 °C. With a 10 kΩ pull-up, output current is ~0.33 mA - well within the 4.0 mA test condition, ensuring VOL remains <0.2 V in practice and meeting I²C standard requirements.

Does the IOFF feature protect against back-current when only VCC is grounded but inputs remain at 3.6 V?

Yes. The IOFF circuit activates when VCC = 0 V, disabling all outputs and limiting IOFF leakage to ±0.75 μA maximum even with inputs or outputs biased to 3.6 V. This meets JESD78B Class II latch-up immunity and prevents damage during hot-swap or partial system power-down.

Is the Schmitt-trigger hysteresis voltage specified, or only implied by VIH/VIL min/max values?

Hysteresis is not directly specified as a single value, but is derived from VIH min and VIL max: at VCC = 3.3 V, VIH min = 2.0 V and VIL max = 0.9 V, yielding ≥1.1 V hysteresis. This exceeds typical TTL hysteresis (≈0.8 V) and ensures reliable switching on noisy or slowly transitioning signals.

What is the maximum capacitive load the 74AUP3G07GNX can drive while maintaining tpd < 5 ns at 3.3 V?

At VCC = 3.3 V, tpd is ≤3.6 ns for CL = 5 pF and ≤4.5 ns for CL = 10 pF (–40 °C to +125 °C). To guarantee tpd < 5 ns, the device supports up to 10 pF total load - including trace capacitance, probe effects, and connected input capacitance - making it suitable for short-run interconnects and low-fanout routing.
