Nexperia USA Inc. 74AUP1G14GX,125

Overview

74AUP1G14GX,125 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 ±20 mA output drive, features IOFF partial power-down protection, and supports -40 °C to +125 °C operation in X2SON5 (SOT1226-3) package. It is used in waveform shaping and relaxation oscillator circuits where noise immunity and rail-to-rail input tolerance are critical.

For engineers reviewing the 74AUP1G14GX,125 datasheet, 74AUP1G14GX,125 pinout, 74AUP1G14GX,125 application, or 74AUP1G14GX,125 equivalent, key selection criteria include its 0.9 μA max ICC at 125 °C, 5-pin X2SON5 thermal-enhanced footprint, Schmitt-trigger hysteresis (0.79–1.31 V at 3.0 V), IOFF-enabled system-level power sequencing, and compatibility with JEDEC standards JESD8-12 through JESD8C.

Technical Context

This device implements a single-channel CMOS inverter with hysteresis on the input stage, enabling robust noise rejection in slow-rising or noisy signal environments. Its Schmitt-trigger transfer characteristic defines distinct VT+ (1.88–2.32 V) and VT− (0.88–1.24 V) thresholds at 3.0 V supply, yielding 0.79–1.31 V hysteresis voltage (VH).

The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA and supporting hot-insertion and partial power-down architectures. Dynamic performance is load-dependent: propagation delay ranges from 1.5 ns (CL = 5 pF, VCC = 3.0–3.6 V) to 7.4 ns (CL = 30 pF, same conditions), with CPD = 4.3 pF at 3.0–3.6 V enabling precise dynamic power estimation.

FAQ

What is the maximum allowable input voltage when VCC = 0.8 V?

The 74AUP1G14GX,125 supports overvoltage-tolerant inputs up to 3.6 V regardless of VCC level. When VCC = 0.8 V, VI may safely reach 3.6 V without damage or functional degradation, enabling interoperability with higher-voltage peripherals without external level-shifting circuitry.

Does the IOFF feature require external control signals?

No. IOFF is fully automatic and requires no external enable/disable pins or configuration. The circuitry activates when VCC drops to 0 V, disabling the output driver and limiting leakage to ±0.75 μA-ensuring safe isolation during power-down sequences without firmware or hardware intervention.

Can this device be used in a relaxation oscillator at 3.3 V supply?

Yes. The 74AUP1G14GX,125 is explicitly validated for relaxation oscillator use (Fig. 11 in datasheet). At VCC = 3.3 V, typical VT+ = 2.22 V and VT− = 1.17 V yield VH ≈ 1.05 V, enabling stable oscillation with standard RC values. Propagation delay remains under 4 ns, supporting frequencies up to several hundred kHz.

Is the X2SON5 (SOT1226-3) package compatible with standard reflow profiles?

Yes. The X2SON5 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and supports standard lead-free reflow profiles (peak 260 °C). Its 0.32 mm height and wettable flanks facilitate automated optical inspection (AOI) and reliable solder joint formation in high-volume SMT lines.
