Nexperia USA Inc. 74AUP2G3407GNH

Overview

74AUP2G3407GNH from Nexperia is a dual-output low-power logic buffer IC featuring one standard CMOS output (1Y) and one open-drain output (2Y), operating across 0.8 V to 3.6 V supply. It integrates Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and delivers ICC ≤ 1.4 μA max at −40 °C to +125 °C - used in voltage-level translation and I²C bus interface conditioning.

For engineers reviewing the 74AUP2G3407GNH datasheet, 74AUP2G3407GNH pinout, 74AUP2G3407GNH application, or 74AUP2G3407GNH equivalent, key selection criteria include dual-output topology (push-pull + open-drain), sub-1.5 μA static current, IOFF-enabled hot-swap capability, and −40 °C to +125 °C industrial temperature rating.

Technical Context

This device implements two independent buffer functions in a single 6-terminal XSON package: input 1A drives push-pull output 1Y with VOH ≥ VCC − 0.11 V (IO = −20 μA); input 2A drives open-drain output 2Y with VOL ≤ 0.50 V (IO = 4.0 mA) and high-impedance OFF state (Z) when input is HIGH. Both inputs feature Schmitt-trigger thresholds (VIH/VIL varying with VCC) enabling robust operation with slow-rising signals.

The IOFF circuit activates when VCC = 0 V, limiting VI/VO leakage to ±0.75 μA and preventing backflow current - critical for partial power-down systems. Propagation delay ranges from 1.0 ns (VCC = 3.0 V, CL = 5 pF) to 11.4 ns (VCC = 3.0 V, CL = 30 pF), with CPD = 4.0 pF (1Y) and 1.2 pF (2Y) defining dynamic power consumption.

FAQ

What is the function of the 2Y open-drain output?

The 2Y terminal operates as an open-drain output: it actively pulls LOW when 2A input is LOW, and enters high-impedance (Z) state when 2A is HIGH. This requires an external pull-up resistor to define the HIGH voltage level and enables wired-AND logic, I²C compatibility, and level translation without direction-control pins.

Can 74AUP2G3407GNH operate at 0.8 V supply while driving a 5 pF load?

Yes - at VCC = 0.8 V, the device guarantees tpd ≤ 13.3 ns (typical) with CL = 5 pF and maintains VIH ≥ 0.70×VCC and VOL ≤ 0.1 V (IO = 20 μA). Its Schmitt-trigger inputs ensure reliable switching even with marginal rise/fall times at minimum voltage.

How does the IOFF feature protect the device during partial power-down?

When VCC = 0 V, the IOFF circuit disables both outputs (1Y and 2Y), limiting VI/VO leakage to ±0.75 μA. This prevents reverse current flow from powered downstream circuits (e.g., 3.3 V bus) into the unpowered IC, eliminating latch-up risk and enabling safe hot-plug operation in modular systems.

Is the 74AUP2G3407GNH pin-compatible with other 6-pin XSON logic buffers?

No - while SOT1115 (0.9×1.0 mm) matches footprint dimensions of some 6-pin XSON logic devices, pin assignment (1A-GND-2A-2Y-VCC-1Y) is unique to the 74AUP2G3407 family. Substitution requires schematic and layout revision; verify against Nexperia's official pinout diagrams before redesign.
