Nexperia USA Inc. 74AXP2G07GXZ

Overview

74AXP2G07GXZ from Nexperia is a dual non-inverting buffer IC with open-drain outputs, Schmitt-trigger inputs, and IOFF partial power-down capability. It operates across 0.7 V–2.75 V supply, delivers <0.6 μA static ICC at 85 °C, supports −40 °C to +85 °C ambient range, and features 0.5 pF input capacitance-used in low-power I²C bus level-shifting and mixed-voltage interface translation.

For engineers reviewing the 74AXP2G07GXZ datasheet, 74AXP2G07GXZ pinout, 74AXP2G07GXZ application, or 74AXP2G07GXZ equivalent, key selection criteria include open-drain drive strength (±20 mA), IOFF leakage (<0.5 μA at VCC = 0 V), propagation delay (1.2–3.7 ns at VCC = 2.3–2.7 V), and thermal-enhanced X2SON6 package compatibility with high-density PCB layouts.

Technical Context

This device implements two independent non-inverting buffers, each with Schmitt-trigger input thresholds for noise immunity and tolerance to slow signal edges. The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V while inputs/outputs remain biased up to 2.75 V.

It complies with JEDEC standards JESD8-12A.01 through JESD8-5A.01 across four voltage bands and meets HBM ESD >2000 V and CDM >1000 V. Dynamic performance is characterized by CPD = 1.3 pF at VCC = 2.5 V and output transition time <3.9 ns under 2.7 V operation.

FAQ

Does 74AXP2G07GXZ support true bidirectional level shifting?

No-it functions as a unidirectional buffer with open-drain outputs. True bidirectional level shifting requires external pull-ups on both sides and relies on bus protocol behavior (e.g., I²C), not internal direction control. Its inputs accept up to 2.75 V regardless of VCC, enabling asymmetric voltage translation when used with appropriate external biasing networks.

What is the maximum capacitive load the 74AXP2G07GXZ can drive reliably?

The device is characterized up to 1000 pF load capacitance in application notes, with propagation delay increasing linearly (e.g., +12 ns at 100 pF vs. 0 pF for VCC = 2.5 V). For reliable timing closure in I²C Fast-mode Plus (1 MHz), total bus capacitance-including traces, connectors, and slaves-must stay ≤400 pF to maintain <300 ns rise time per specification.

Can 74AXP2G07GXZ be used without a pull-up resistor on its outputs?

No-open-drain outputs require external pull-up resistors to define HIGH logic level and provide source current. Omitting pull-ups results in undefined output states and bus contention. Recommended values range from 1 kΩ (for speed-critical 100 MHz clocks) to 10 kΩ (for low-power I²C), selected based on VCC, load capacitance, and required rise time.

How does the IOFF feature behave during brown-out conditions?

IOFF activates when VCC drops below ~0.3 V, disabling outputs and limiting backfeed current to <0.5 μA. During brown-out (e.g., VCC = 0.4 V), IOFF is not fully engaged; output leakage rises to ~10 μA. For robust brown-out isolation, pair with a supervisor IC that forces system reset before VCC falls below 0.5 V.
