Nexperia USA Inc. 74AXP1G17GN125

Overview

74AXP1G17GN125 from Nexperia is a single-channel low-power Schmitt trigger buffer designed for signal conditioning in ultra-low-voltage digital systems. It converts slow-rising/falling input signals into clean, jitter-free CMOS-compatible outputs with hysteresis, operates across 0.7 V to 2.75 V supply range, delivers <1.0 ns transition time at 2.7 V, and supports partial power-down via IOFF circuitry. It is used in battery-powered sensor interfaces and I²C bus level-shifting circuits.

For engineers reviewing the 74AXP1G17GN125 datasheet, 74AXP1G17GN125 pinout, 74AXP1G17GN125 application, or 74AXP1G17GN125 equivalent, key selection criteria include supply voltage flexibility (0.7–2.75 V), sub-1 pF input capacitance, IOFF-enabled power-gating capability, and guaranteed operation from –40 °C to +85 °C in XSON6 packaging.

Technical Context

The device implements a single Schmitt-triggered inverting buffer stage with asymmetric threshold voltages (VT+ and VT−) enabling noise-immune signal regeneration. Its IOFF circuit actively disables output terminals during VCC = 0 V, blocking backflow current and enabling hot-swap and partial power-down system architectures.

It complies with JEDEC standards JESD8-12A.01 through JESD8-5A.01 across multiple voltage bands and meets HBM ESD >2 kV and CDM >1000 V requirements. Input tolerance up to 2.75 V allows interfacing with higher-voltage logic domains without external level shifters.

FAQ

What is the maximum input voltage the 74AXP1G17GN125 can tolerate when VCC = 0 V?

The device accepts input voltages up to 2.75 V regardless of VCC state, including VCC = 0 V. This is confirmed in Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions), where VI is specified from –0.5 V to +3.3 V, and functional operation is guaranteed up to 2.75 V. The IOFF circuit blocks backflow current under these conditions.

Does the 74AXP1G17GN125 support true bidirectional signal translation?

No. It is a unidirectional Schmitt trigger buffer with fixed input (pin 2) and output (pin 4) roles. There is no internal feedback path or direction-control logic. Bidirectional translation requires separate devices or dedicated bus transceivers like the NXH0102UK.

How does the hysteresis voltage (VH) vary with supply voltage?

VH ranges from 0.06VCC to 0.5VCC depending on VCC level: at 0.75–0.85 V, VH = 0.06VCC–0.5VCC; at 1.1–1.95 V, VH = 0.1VCC–0.4VCC; at 2.3–2.7 V, VH = 0.2–1.0 V (Table 7). This scaling ensures consistent noise margin across its full 0.7–2.75 V operating range.

Is the SOT1115 (XSON6) package RoHS-compliant and lead-free?

Yes. Nexperia confirms all 74AXP1G17 variants, including SOT1115, meet RoHS Directive 2011/65/EU and are lead-free, halogen-free, and compliant with REACH SVHC requirements. Full compliance documentation is available in Nexperia's Product Compliance Database under document ID "PCB-74AXP1G17".
