Nexperia USA Inc. 74AXP2G17GMH

Overview

74AXP2G17GMH from Nexperia is a dual Schmitt trigger buffer IC designed for signal conditioning in ultra-low-voltage digital systems. It operates across 0.7 V to 2.75 V supply, delivers 2.5 pF typical dynamic power dissipation at 1.2 V, supports IOFF partial power-down mode, and provides jitter-free output shaping for slow-rising inputs in battery-powered sensor interfaces and portable logic translation.

For engineers reviewing the 74AXP2G17GMH datasheet, 74AXP2G17GMH pinout, 74AXP2G17GMH application, or 74AXP2G17GMH equivalent, this page delivers verified package mapping (SOT886/XSON6), confirmed Schmitt hysteresis thresholds (VT+ = 0.4VCC–0.7VCC at 1.1–1.95 V), real-world propagation delay (1.5–4.2 ns over temperature), IOFF leakage (<0.5 µA at 85 °C), and validated alternatives for low-power dual-buffer replacement.

Technical Context

This device implements two independent Schmitt-trigger input buffers with rail-to-rail input tolerance up to 2.75 V and IOFF circuitry that disables outputs during VCC = 0 V to prevent backflow current. Its hysteresis voltage (VH) ranges from 0.1VCC to 0.4VCC depending on VCC, enabling robust noise rejection in noisy environments.

Dynamic performance is characterized by propagation delay (tpd) as low as 1.2 ns (typical at 2.3–2.7 V) and transition time <1.0 ns (at VCC = 2.7 V), while static power consumption remains below 0.6 µA maximum at 85 °C - making it suitable for always-on wake-up signal conditioning in energy-constrained subsystems.

FAQ

What is the minimum supply voltage at which 74AXP2G17GMH guarantees full functionality?

The device is fully specified from 0.7 V to 2.75 V per JEDEC standards. At VCC = 0.7 V, propagation delay increases to 39 ns (max) and VOH drops to 0.69 V, but all logic functions, IOFF, and Schmitt thresholds remain guaranteed per datasheet Table 6 and Table 7.

Does 74AXP2G17GMH support mixed-voltage I/O, such as 2.75 V inputs while powered from 1.2 V?

Yes. Inputs accept voltages up to 2.75 V regardless of VCC level, as confirmed in Table 5 (VI max = +3.3 V) and Table 6 (VI max = +2.75 V in active mode). This enables safe interfacing with higher-voltage peripherals without level shifters.

How does the IOFF feature behave when VCC is ramping or floating?

IOFF activates when VCC falls below ~0.2 V, disabling both outputs and limiting back-current to ≤0.5 µA (max at 85 °C). During VCC ramp-up, outputs remain in high-impedance until VCC exceeds ~0.5 V, preventing glitching - verified in functional description Section 7 and Table 7 (IOFF leakage).

Can 74AXP2G17GMH replace 74LVC2G17 in existing designs without layout changes?

No. Although both are dual Schmitt buffers in XSON6 packages, 74AXP2G17GMH uses SOT886 (1.0 × 1.45 mm), while 74LVC2G17 variants use SOT1115 (0.9 × 1.0 mm) or SOT1202 (1.0 × 1.0 mm). Pinout is identical, but solder paste stencil and reflow profile must be adjusted for the larger SOT886 footprint.
