Nexperia USA Inc. 74AXP2G3404GSH

Overview

74AXP2G3404 from Nexperia is a dual-function logic device integrating one Schmitt-trigger buffer (1A→1Y) and one Schmitt-trigger inverter (2A→2Y) in a single XSON6 package. It operates across 0.7 V to 2.75 V supply, delivers ultra-low static current (≤0.6 µA at 85 °C), supports partial power-down via IOFF, and targets space-constrained, battery-sensitive applications such as portable sensor interfaces and low-power microcontroller I/O conditioning.

For engineers reviewing the 74AXP2G3404 datasheet, 74AXP2G3404 pinout, 74AXP2G3404 application, or 74AXP2G3404 equivalent, key selection criteria include its dual-buffer/inverter functionality with Schmitt-trigger inputs, sub-1 µA ICC at 85 °C, IOFF-enabled power-down isolation, 0.5 pF input capacitance, and compatibility with JEDEC voltage standards JESD8-12A.01 through JESD8-5A.01.

Technical Context

This device implements two independent CMOS logic gates-buffer and inverter-each with Schmitt-trigger input thresholds for noise immunity and tolerance of slow-rising/falling signals. Input hysteresis ensures clean switching even with noisy or slew-limited waveforms.

Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±2.75 V on I/O pins. The design supports mixed-voltage system interfacing, with inputs rated to 2.75 V regardless of VCC level, and guaranteed operation from −40 °C to +85 °C.

Key Specifications

Pinout & Package

FAQ

Does the 74AXP2G3404 support true bidirectional I/O?

No. It is a unidirectional logic device: 1A drives 1Y (buffer), and 2A drives 2Y (inverter). Neither output can function as an input, and there is no internal bus-hold or direction-control logic. Its IOFF feature only disables output drivers during power-down-it does not enable data flow reversal.

Can 74AXP2G3404 inputs be driven above VCC without damage?

Yes. Inputs tolerate voltages up to 2.75 V regardless of VCC level, including when VCC = 0 V. This is enabled by diode-clamped input structures and is validated per JEDEC JESD78 latch-up testing (>100 mA). However, sustained overvoltage beyond 2.75 V risks permanent damage.

What is the minimum load capacitance for guaranteed tpd specification?

The propagation delay (tpd) values in Table 9 are characterized with a 5 pF load capacitance (CL), per Figure 12 test setup. Performance degrades linearly with increasing CL; for example, at 15 pF and VCC = 1.8 V, tpd increases ~30% versus the 5 pF baseline. No minimum CL is specified-the device functions correctly down to near-zero load.

Is the 74AXP2G3404 qualified for automotive applications?

No. Per Nexperia's legal disclaimers (Section 16.3), this device is explicitly labeled "non-automotive qualified" and has not undergone AEC-Q100 stress testing or automotive-grade screening. It is intended for industrial and commercial use only; automotive deployment requires formal qualification and carries no warranty coverage.
