Nexperia USA Inc. 74AUP3G3404GSX

Overview

74AUP3G3404 from Nexperia is a low-power triple-gate logic device integrating two non-inverting buffers (1A→1Y, 2A→2Y) and one inverting buffer (3A→3Y), with Schmitt-trigger inputs enabling robust noise immunity across 0.8 V–3.6 V supply operation. It delivers ICC ≤ 0.9 μA max static current, IOFF-enabled partial power-down protection, and propagation delays as low as 1.1 ns (VCC = 3.0–3.6 V, CL = 5 pF), targeting battery-powered sensor interfaces and I/O level-shifting in portable industrial controllers.

For engineers reviewing the 74AUP3G3404 datasheet, 74AUP3G3404 pinout, 74AUP3G3404 application, or 74AUP3G3404 equivalent, key selection criteria include its dual-buffer + inverter topology, ultra-low ICC at sub-1-V operation, IOFF leakage < ±0.75 μA during power-down, and guaranteed Schmitt-trigger hysteresis across full VCC range - critical for noisy microcontroller GPIO expansion and legacy signal conditioning.

Technical Context

This device implements three independent logic gates in a single 8-terminal XSON package: two identical non-inverting buffers (1Y, 2Y) and one inverting buffer (3Y), each with Schmitt-trigger inputs ensuring clean switching despite slow-rising or noisy signals. All inputs tolerate voltages up to 3.6 V regardless of VCC, supporting mixed-voltage domain interfacing.

The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA maximum and enabling safe hot-insertion in partial-power-down systems. Propagation delay varies from 1.1 ns (3.6 V, 5 pF) to 33.6 ns (0.8 V, 30 pF), with CPD = 4.0 pF at 3.6 V enabling precise dynamic power estimation via PD = CPD × VCC² × fi × N.

FAQ

What is the maximum load capacitance supported while maintaining guaranteed tpd?

The datasheet specifies propagation delay up to CL = 30 pF across all VCC conditions. At VCC = 3.6 V, tpd remains ≤ 7.2 ns (−40 °C to +125 °C), confirming reliable operation with standard PCB trace capacitance plus typical MCU GPIO input capacitance (≤ 5 pF) and scope probe loading (≤ 12 pF).

Can 74AUP3G3404 drive a 50 Ω transmission line directly?

No - its output drive strength is rated for ±4 mA at 3.0 V (VOL ≤ 0.45 V), insufficient for 50 Ω line termination. For impedance-matched signaling, use a dedicated line driver (e.g., SN65LVDS1) or add series termination; this device is intended for point-to-point CMOS loading within same PCB layer.

Does the IOFF feature work when only GND is connected and VCC is floating?

No - IOFF activation requires VCC = 0 V (hard-grounded). A floating VCC violates Absolute Maximum Ratings and may cause undefined output states or increased leakage. Always tie VCC to GND through a low-impedance path (e.g., 0 Ω resistor or direct short) during power-down sequences.

How does Schmitt-trigger hysteresis vary with VCC?

Hysteresis width scales linearly with VCC: typical ΔV = 0.15 × VCC. At VCC = 0.8 V, hysteresis is ~120 mV; at VCC = 3.6 V, it reaches ~540 mV. This proportional behavior ensures consistent noise margin across all operating voltages without recalibration.
