Nexperia USA Inc. 74AXP1G17GMH

Overview

74AXP1G17GMH from Nexperia is a single-channel low-power Schmitt trigger buffer designed for signal conditioning in ultra-low-voltage digital systems. It operates across 0.7 V to 2.75 V supply, delivers jitter-free output with hysteresis (VH = 0.2–1.0 V), features IOFF partial power-down protection, and supports –40 °C to +85 °C industrial temperature range - used in battery-powered sensor interfaces and level-shifting I²C/SPI stubs.

For engineers reviewing the 74AXP1G17GMH datasheet, 74AXP1G17GMH pinout, 74AXP1G17GMH application, or 74AXP1G17GMH equivalent, key selection criteria include its sub-1 V operation capability, 0.5 pF input capacitance, IOFF-enabled system-level power sequencing, and XSON6 (SOT886) 1 × 1.45 × 0.5 mm package compatibility with high-density PCB layouts.

Technical Context

The 74AXP1G17GMH implements a single non-inverting Schmitt trigger with asymmetric threshold voltages (VT+ = 0.3VCC–0.8VCC; VT− = 0.2VCC–0.7VCC), enabling robust noise rejection on slow-rising signals. Its IOFF circuit actively disables outputs during VCC = 0 V, preventing backflow current in multi-rail partial power-down systems.

It complies with JEDEC standards JESD8-12A.01 through JESD8-5A.01 across four voltage bands and achieves HBM ESD >2 kV and CDM >1000 V - confirming suitability for portable electronics with exposed I/O paths and mixed-supply domain interfacing.

FAQ

What is the minimum supply voltage at which 74AXP1G17GMH guarantees functional operation?

The device is fully specified from 0.7 V to 2.75 V per JEDEC-compliant operating conditions. At 0.7 V, propagation delay is 39 ns (max), VT+ is 0.3VCC (0.21 V), and IOFF remains active. Operation below 0.7 V is not characterized and may result in undefined output states or increased ICC.

Can 74AXP1G17GMH drive a 50 pF load while maintaining specified timing?

No - the datasheet specifies timing only up to 15 pF load capacitance (see Fig. 9–13). At 50 pF, propagation delay increases significantly (e.g., ~2× at 2.5 V), and transition time degrades beyond 10 % VCC overshoot limits. For >15 pF loads, add a buffer stage or reduce trace capacitance via layout optimization.

Is pin 1 of 74AXP1G17GMH marked with a dot or notch?

Per datasheet Figure 4 and Table 2, pin 1 is indicated by a laser-marked "rJ" code in the lower-left corner of the package, below which a small indentation (pin 1 index area) is present on the package edge - no molded dot or notch is used; visual identification requires magnification due to 0.3 mm pitch.

Does 74AXP1G17GMH support hot insertion into a live backplane?

Yes - the IOFF circuit ensures outputs are disabled when VCC = 0 V, and inputs tolerate up to 2.75 V regardless of supply state. Combined with ±20 mA output current rating and 2 kV HBM ESD, it meets basic hot-swap requirements for modular sensor or peripheral cards in industrial backplanes.
