Nexperia USA Inc. 74AXP1G04GM125

Overview

74AXP1G04GM125 from Nexperia is a single low-power inverting buffer with Schmitt-trigger inputs, designed for ultra-low-voltage logic interfacing across 0.7 V to 2.75 V supply rails. It delivers 0.5 pF input capacitance, 2.3 pF dynamic power dissipation at 1.2 V, and IOFF-enabled partial power-down protection. It is used in battery-powered sensor nodes and voltage-level translation between sub-1V and 2.7V domains.

For engineers reviewing the 74AXP1G04GM125 datasheet, 74AXP1G04GM125 pinout, 74AXP1G04GM125 application, or 74AXP1G04GM125 equivalent, key selection criteria include its 0.7–2.75 V operating range, IOFF leakage < 0.1 μA at VCC = 0 V, Schmitt-trigger hysteresis for slow-edge immunity, and XSON6 (SOT886) 1.0 × 1.45 × 0.5 mm package compatibility with high-density PCB layouts.

Technical Context

This device implements a single-channel inverter with Schmitt-trigger input thresholds-VIH ≥ 0.65VCC and VIL ≤ 0.35VCC across 1.1–1.95 V VCC-to reject noise on slow-rising signals. Its 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.

Dynamic performance is characterized by propagation delay tpd = 1.0–11 ns (depending on VCC and load), transition time tt ≤ 1.0 ns at 2.7 V, and guaranteed operation from –40 °C to +85 °C. The logic function is strictly inverting (A → Y), with no enable or control pins-pure signal inversion with robust DC and transient behavior.

FAQ

Can 74AXP1G04GM125 operate at 0.7 V supply while driving a 15 pF load?

Yes. At VCC = 0.7 V, the device guarantees tpd ≤ 33 ns into 15 pF (per Fig. 7), VOH ≥ 0.69 V, and VOL ≤ 0.1 V under specified test conditions. Static current remains ≤ 0.3 μA, making it viable for ultra-low-power wake-up paths where speed is secondary to energy efficiency.

Does the IOFF feature protect against back-current when VCC = 0 V and input is pulled to 2.75 V?

Yes. With VCC = 0 V, IOFF limits input/output leakage to ≤ 0.1 μA (typical) even when VI or VO = 2.75 V. This meets JESD78 Class II latch-up immunity (>100 mA) and prevents destructive current flow from live rails into unpowered sections during power sequencing.

Is pin 1 of the SOT886 package marked with a dot or notch?

No. Per datasheet Figure 4 and Table 2, pin 1 is identified by a laser-marked "rC" code with the pin 1 indicator located in the lower-left corner below the marking-there is no physical dot, notch, or chamfer on the XSON6 body.

How does Schmitt-trigger action improve noise immunity compared to standard CMOS inverters?

It provides input hysteresis: VIH (≥0.65VCC) and VIL (≤0.35VCC) differ by ≥30% of VCC, so noise spikes <150 mV at 1.2 V cannot cause false toggling. This eliminates need for external RC filters on slow edges-critical for reliability in motor-drive feedback or environmental sensor outputs.
