Nexperia USA Inc. 74AXP1G14GSH

Overview

74AXP1G14GSH from Nexperia is a single-channel low-power Schmitt trigger inverter IC 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 is qualified for -40 °C to +85 °C industrial environments - used in battery-powered sensor interfaces and level-shifting I²C pull-up networks.

For engineers reviewing the 74AXP1G14GSH datasheet, 74AXP1G14GSH pinout, 74AXP1G14GSH application, or 74AXP1G14GSH equivalent, key selection criteria include its sub-1 V operation capability, 0.5 pF input capacitance, IOFF-enabled bus isolation, and compatibility with JEDEC standards JESD8-12A.01 through JESD8-5A.01.

Technical Context

This device implements a single inverting Schmitt trigger gate with asymmetric hysteresis thresholds (VT+ = 0.9–1.7 V, VT− = 0.7–1.5 V at VCC = 2.3–2.7 V) to reject noise on slow-rising/falling signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

It supports dynamic operation down to 0.7 V with propagation delay as low as 1.2 ns (typ.) at VCC = 2.7 V and load CL = 0 pF, while maintaining static ICC ≤ 0.6 μA at 85 °C - enabling integration into always-on, energy-constrained subsystems such as real-time clock supervisors and wake-up signal conditioners.

FAQ

Does 74AXP1G14GSH support operation below 1.0 V?

Yes - it is fully specified from 0.7 V to 2.75 V supply, with functional performance including hysteresis, propagation delay, and IOFF activation confirmed down to 0.7 V. Static ICC remains ≤ 0.6 μA at 85 °C, and tpd is 3 ns (typ.) at VCC = 0.8 V, making it suitable for sub-1 V energy-harvesting and ultra-low-power MCU interfaces.

What is the purpose of the two n.c. pins on the XSON6 package?

Pins 1 and 5 are internally unconnected and must remain floating - they serve mechanical and thermal roles in the XSON6 package structure but carry no electrical function. Connecting them risks parasitic coupling or thermal imbalance; Nexperia explicitly states these pins are "not connected" in Table 3 and Fig. 4.

How does IOFF behave when VCC is ramping or partially powered?

IOFF activates automatically when VCC drops below ~0.1 V, disabling the output driver and limiting backflow current to ±0.1 μA max. During VCC ramp-up, the output remains in high-impedance state until VCC exceeds the minimum functional threshold (~0.7 V), ensuring glitch-free enablement without bus contention.

Can 74AXP1G14GSH drive standard 50 Ω transmission lines?

No - its output drive strength is rated for CMOS loads (±8 mA at VCC = 2.3 V), not 50 Ω termination. Driving 50 Ω directly would exceed VOL/VOH specifications and cause excessive power dissipation. For transmission line driving, use a dedicated line driver or buffer IC with appropriate impedance matching.
