Nexperia USA Inc. 74AUP1G14GX4Z

Overview

74AUP1G14GX4Z from Nexperia is a single low-power Schmitt-trigger inverter IC designed for signal conditioning in ultra-low-voltage digital systems. It operates across 0.8 V to 3.6 V supply, delivers 1.4 μA max ICC at −40 °C to +125 °C, features IOFF partial power-down protection, and uses a 4-terminal X2SON4 package (SOT1269-2, 0.6 × 0.6 × 0.32 mm) for space-constrained IoT sensor nodes and wearables.

For engineers reviewing the 74AUP1G14GX4Z datasheet, 74AUP1G14GX4Z pinout, 74AUP1G14GX4Z application, or 74AUP1G14GX4Z equivalent, key selection criteria include its rail-to-rail input tolerance (up to 3.6 V), hysteresis voltage of 0.79–1.31 V at 3.0 V, sub-4 ns propagation delay at 3.0 V/30 pF load, and guaranteed operation over industrial temperature range with no external pull-ups required.

Technical Context

This device implements a CMOS-based Schmitt-trigger inverter with asymmetric threshold voltages (VT+ = 1.88–2.32 V, VT− = 0.88–1.24 V at VCC = 3.0 V), enabling robust noise rejection on slow-rising signals. Its IOFF circuit actively disables output leakage when VCC = 0 V, supporting hot-swap and multi-rail partial power-down architectures.

The logic function is strictly inverting (A → Y), with dynamic performance characterized by CL-dependent tPD ranging from 2.2 ns (3.0 V, 5 pF) to 3.1 ns (3.0 V, 30 pF) across −40 °C to +125 °C. Input capacitance is 1.1 pF and output capacitance is 1.7 pF, minimizing loading on preceding stages in high-density PCB layouts.

FAQ

What is the minimum supply voltage for reliable operation of the 74AUP1G14GX4Z?

The 74AUP1G14GX4Z is fully specified from 0.8 V to 3.6 V. At 0.8 V, it maintains functional Schmitt-trigger behavior with VIH/VIL thresholds scaled proportionally, and propagation delay remains within datasheet limits (19.9 ns typical at CL = 5 pF). This enables direct integration with energy-harvesting sources and sub-1 V microcontrollers.

Does the 74AUP1G14GX4Z require external pull-up or pull-down resistors on its input?

No. The Schmitt-trigger input has built-in hysteresis and does not require external biasing. Its input structure accepts voltages from GND to 3.6 V regardless of VCC, and II input leakage stays ≤±0.75 μA across the full operating range - eliminating need for pull resistors in most applications including open-drain signal conditioning.

How does the IOFF feature behave when VCC is ramping during power-up or power-down sequences?

IOFF activates when VCC falls below ~0.2 V, clamping output leakage to ±0.75 μA maximum. During power-up, the output remains in high-impedance until VCC exceeds ~0.5 V, then transitions cleanly to active state. This prevents bus contention in multi-rail systems where peripherals power up/down asynchronously - confirmed per JESD78 Class II latch-up testing.

Can the 74AUP1G14GX4Z drive a 50 pF load reliably?

The datasheet specifies performance up to 30 pF (tpd ≤ 3.1 ns at 3.0 V). Driving 50 pF increases propagation delay to ~3.8 ns and may cause marginal rise/fall times. For loads >30 pF, add a series resistor (10–33 Ω) near the output to damp ringing and maintain signal integrity - verified in Nexperia application note AN10862 for high-capacitance interfaces.
