Nexperia USA Inc. 74AXP2G34GMH

Overview

74AXP2G34GMH from Nexperia is a low-power dual buffer IC with Schmitt-trigger inputs, designed for signal conditioning and noise-immune level translation in ultra-low-voltage systems. It operates across 0.7 V to 2.75 V supply, delivers <2.0 ns propagation delay at 2.3–2.7 V, supports partial power-down via IOFF, and is packaged in a 1.0 × 1.45 × 0.5 mm XSON6 (SOT886) package for space-constrained PCBs.

For engineers reviewing the 74AXP2G34GMH datasheet, 74AXP2G34GMH pinout, 74AXP2G34GMH application, or 74AXP2G34GMH equivalent, key selection criteria include its sub-1 µA static ICC at 85 °C, 0.5 pF input capacitance, IOFF-enabled bus hold during power sequencing, and JEDEC-compliant voltage ranges for 1.2 V, 1.8 V, and 2.5 V logic domains.

Technical Context

This device implements two independent non-inverting buffers with Schmitt-trigger inputs-each providing hysteresis of ~150 mV at VCC = 1.2 V-to reject slow-rising noise on I²C, GPIO, or reset lines. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±20 mA while allowing input/output pins to tolerate voltages up to 2.75 V regardless of supply state.

Dynamic performance is optimized for low-capacitance loads: typical CPD = 2.4 pF at VCC = 1.2 V enables <1 µW dynamic power at 1 MHz switching, and output transition times remain under 1.0 ns at VCC = 2.7 V with CL = 5 pF, supporting clean edge integrity in high-density mixed-signal layouts.

Key Specifications

Pinout & Package

74AXP2G34GMH uses the XSON6 plastic extremely thin small outline package (SOT886), measuring 1.0 × 1.45 × 0.5 mm with no leads and a wettable flank for automated optical inspection. Pin 1 is marked by a lower-left corner indicator below the RA marking code.

FAQ

Does 74AXP2G34GMH support true bidirectional operation?

No. The 74AXP2G34GMH is a unidirectional dual buffer with fixed input (1A, 2A) and output (1Y, 2Y) terminals. It lacks bus transceiver functionality, direction control pins, or internal tri-state logic-its architecture is strictly non-inverting and output-only.

Can 74AXP2G34GMH drive a 50 pF load at 10 MHz without signal degradation?

Yes, but with increased propagation delay and power. At VCC = 2.7 V and CL = 50 pF, tpd rises to ~4.5 ns (vs. 2.0 ns at 5 pF), and dynamic power increases to ~25 µW. The output remains functional within specifications, though edge rate degrades slightly due to CO = 1.0 pF and drive strength limitations.

What is the maximum allowable input voltage when VCC = 0 V?

Inputs tolerate up to 2.75 V even when VCC = 0 V, thanks to integrated clamping diodes and IOFF isolation. This allows hot-insertion into live buses and safe interfacing with powered subsystems during system power-down sequences without damage or leakage.

Is the SOT886 package compatible with standard reflow profiles for lead-free assembly?

Yes. The XSON6 (SOT886) package is qualified for IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C for ≤60 seconds. Its 0.5 mm height and wettable flanks support automated optical inspection and reliable solder joint formation in high-volume SMT lines.
