Nexperia USA Inc. 74AXP1G09GXH

Overview

74AXP1G09GXH from Nexperia is a single 2-input AND gate with open-drain output, designed for low-voltage logic interfacing and wired-AND/wired-OR bus configurations. It operates across 0.7 V to 2.75 V supply range, delivers <0.6 μA max static ICC at 85 °C, features IOFF partial power-down protection, and supports −40 °C to +85 °C industrial temperature operation.

For engineers reviewing the 74AXP1G09GXH datasheet, 74AXP1G09GXH pinout, 74AXP1G09GXH application, or 74AXP1G09GXH equivalent, key selection criteria include open-drain compatibility with mixed-voltage I²C buses, ultra-low dynamic capacitance (CI = 0.5 pF, CO = 0.7 pF), and guaranteed IOFF behavior during system power sequencing.

Technical Context

The device implements standard AND logic (Y = A · B) with an open-drain output stage, requiring an external pull-up resistor to define HIGH-level voltage and current sourcing capability. Its IOFF circuit actively disables output leakage when VCC = 0 V, preventing backflow current in partial power-down systems.

Propagation delay ranges from 1.1 ns (min, VCC = 2.3 V) to 88 ns (max, VCC = 0.75 V), scaling inversely with supply voltage and load capacitance. Input thresholds are ratio-based (VIH = 0.65VCC min, VIL = 0.35VCC max) and compliant with JEDEC standards JESD8-12A.01 through JESD8-5A.01.

FAQ

What is the function of the IOFF feature in 74AXP1G09GXH?

The IOFF circuit disables the output buffer when VCC = 0 V, blocking reverse current flow from powered I/O lines into the unpowered device. This prevents damage and system instability during partial power-down or hot-swap events, eliminating need for external isolation components in multi-rail systems.

Can 74AXP1G09GXH drive a 15 pF bus load at 2.5 V while meeting I²C timing?

Yes. At VCC = 2.5 V and CL = 15 pF, propagation delay remains ≤4.4 ns (typical), and transition time stays under 1 ns. Combined with its 0.7 pF CO and support for external pull-ups ≥2 kΩ, it meets standard-mode (100 kHz) and fast-mode (400 kHz) I²C rise-time requirements without additional buffering.

Is the 74AXP1G09GXH pin-compatible with other X2SON5 logic gates?

No. While sharing the SOT1226-3 (X2SON5) 5-pin footprint, pin assignments differ across functions: 74AXP1G09GXH uses pins 1(B), 2(A), 3(GND), 4(Y), 5(VCC); inverters like 74AXP1G04GXH assign Y to pin 5 and VCC to pin 4. Mechanical fit does not guarantee electrical or functional compatibility.

How does the 74AXP1G09GXH handle input voltages exceeding VCC?

Inputs accept voltages up to 2.75 V regardless of VCC level, enabling robust interfacing with higher-voltage peripherals. Internal clamping diodes and ESD structures limit input current to ±50 mA under fault conditions, and static characteristics remain valid for VI = 0–2.75 V per Table 6.
