Nexperia USA Inc. 74AUP1G14GM,115

Overview

74AUP1G14GM,115 from Nexperia is a single-channel Schmitt-trigger inverter IC designed for signal conditioning in ultra-low-power 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 is packaged in XSON6 (SOT886) with 6 terminals. It enables clean waveform shaping in battery-powered sensor interfaces and IoT edge nodes.

For engineers reviewing the 74AUP1G14GM,115 datasheet, 74AUP1G14GM,115 pinout, 74AUP1G14GM,115 application, or 74AUP1G14GM,115 equivalent, key selection criteria include its rail-to-rail input hysteresis (VH = 0.79–1.31 V at VCC = 3.0 V), sub-1.5 ns propagation delay at 3.0 V/5 pF, IOFF leakage < ±0.75 μA during power-down, and guaranteed operation over −40 °C to +125 °C.

Technical Context

This device implements a CMOS-based Schmitt-trigger inverter with asymmetric input thresholds (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 outputs when VCC = 0 V, preventing backflow current in mixed-voltage or hot-swap subsystems.

The AUP logic family uses optimized transistor sizing to achieve ultra-low static power (ICC ≤ 1.4 μA) while maintaining full-speed performance: tPD = 1.5–4.0 ns over VCC = 3.0–3.6 V with CL = 5–30 pF. Input tolerance up to 3.6 V allows interfacing with higher-voltage logic without level shifters.

FAQ

What is the minimum supply voltage for guaranteed operation?

The 74AUP1G14GM,115 is fully specified from 0.8 V to 3.6 V. At 0.8 V, it maintains functional logic behavior with tPD up to 19.9 ns (CL = 5 pF) and VOH/VOL meeting rail-to-rail thresholds. This enables direct use with single-cell LiFePO₄ (2.5–3.6 V) or multi-cell alkaline (0.9–1.5 V) sources without regulation.

How does the IOFF feature protect downstream circuitry?

When VCC = 0 V, the IOFF circuit disconnects both input and output paths internally, limiting VI/O leakage to ±0.75 μA. This prevents reverse current flow from powered sections (e.g., 3.3 V I²C bus) into unpowered domains, avoiding latch-up, data corruption, or damage to isolated subsystems during power sequencing.

Can this device drive a 50 pF load reliably?

No - the datasheet specifies dynamic characteristics only up to CL = 30 pF. At 50 pF, propagation delay increases beyond guaranteed limits (e.g., >7.4 ns at VCC = 3.0 V), and output rise/fall times degrade, risking setup/hold violations. For >30 pF loads, add a buffer stage or select a higher-drive logic family.

Is the XSON6 (SOT886) package compatible with standard reflow profiles?

Yes - SOT886 is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1), supporting peak reflow temperatures up to 260 °C. Its 0.5 mm height and thermal pad enable efficient heat transfer; recommended profile includes ramp rate ≤3 °C/s, preheat 150–200 °C for 60–120 s, and time above liquidus 60–90 s at 235–245 °C.
