Nexperia USA Inc. 74AXP2G3404GNH

Overview

74AXP2G3404 from Nexperia is a dual-function low-power logic IC containing one Schmitt-trigger buffer (1A→1Y) and one Schmitt-trigger inverter (2A→2Y), operating across 0.7 V–2.75 V supply. It delivers ultra-low static current (0.6 µA max at 85 °C), IOFF-enabled partial power-down protection, and sub-1 ns transition times at 2.7 V. Used in battery-powered sensor interfaces and voltage-level translation between mixed-supply subsystems.

For engineers reviewing the 74AXP2G3404 datasheet, 74AXP2G3404 pinout, 74AXP2G3404 application, or 74AXP2G3404 equivalent, key selection criteria include its dual Schmitt-trigger inputs for noise immunity, IOFF leakage control under power-down, wide-VCC compatibility down to 0.7 V, and XSON6 footprint constraints for space-constrained portable designs.

Technical Context

This device implements two independent CMOS logic gates with Schmitt-trigger inputs on a single die, enabling robust signal conditioning of slow-rising or noisy digital signals without external hysteresis components. Each gate features rail-to-rail input tolerance up to 2.75 V regardless of VCC level.

The IOFF circuit actively disables both outputs when VCC = 0 V, limiting backflow current to ≤0.5 µA (max) and meeting JEDEC JESD78 Class II latch-up immunity (>100 mA). Propagation delay ranges from 0.9 ns (VCC = 2.3–2.7 V) to 110 ns (VCC = 0.75–0.85 V), scaling predictably with supply voltage and load.

FAQ

What is the maximum input voltage the 74AXP2G3404 can tolerate when VCC = 0 V?

The device accepts input voltages up to 2.75 V on any pin-including 1A, 2A, 1Y, and 2Y-even when VCC = 0 V. This is enabled by its IOFF circuitry, which isolates the internal core and prevents damaging back-current flow, making it safe for hot-insertion scenarios where I/O pins may be driven before power is applied.

Does the 74AXP2G3404 support true bidirectional signal conditioning?

No. The 74AXP2G3404 is strictly unidirectional: 1A drives 1Y (buffer), and 2A drives 2Y (inverter). Neither output can drive its corresponding input, and there is no internal feedback path or bus-hold feature. Its role is signal shaping and polarity inversion-not data direction control or bus arbitration.

How does the Schmitt-trigger hysteresis vary with supply voltage?

Hysteresis is proportional to VCC: at VCC = 1.1–1.95 V, VIH = 0.65×VCC and VIL = 0.35×VCC, yielding ~0.3×VCC hysteresis (e.g., ~330 mV at 1.1 V, ~590 mV at 1.95 V). At VCC = 2.3–2.7 V, fixed VIH = 1.6 V and VIL = 0.7 V produce ~900 mV hysteresis, ensuring consistent noise margin across the full operating range.

Can the 74AXP2G3404 drive a 50 Ω transmission line directly?

No. With typical output drive strength of ±8 mA at VCC = 2.3 V, the 74AXP2G3404 cannot sustain 50 Ω termination (requiring ±50 mA for 2.5 V swing). It is intended for point-to-point routing to high-impedance CMOS inputs (≥10 kΩ) or short PCB traces (<5 cm). For 50 Ω line driving, a dedicated line driver or buffer with higher current capability is required.
