Nexperia USA Inc. 74AUP1G14GW,125

Overview

74AUP1G14GW,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 TSSOP5 (SOT353-1) 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 74AUP1G14GW,125 datasheet, 74AUP1G14GW,125 pinout, 74AUP1G14GW,125 application, or 74AUP1G14GW,125 equivalent, key selection criteria include its 0.9 μA max ICC at 3.6 V, 1.24 V typical hysteresis at 3.0 V, IOFF-enabled system-level power sequencing, and compatibility with JEDEC standards JESD8-12 through JESD8C.

Technical Context

The device implements a CMOS-based Schmitt-trigger input stage with asymmetric threshold voltages (VT+ ≈ 2.29 V, VT− ≈ 1.24 V at VCC = 3.0 V), enabling robust noise rejection on slow-rising or noisy signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

Dynamic performance is load- and voltage-dependent: propagation delay ranges from 1.5 ns (CL = 5 pF, VCC = 3.6 V) to 20.0 ns (CL = 30 pF, VCC = 1.1 V). Power dissipation capacitance CPD is 4.3 pF at VCC = 3.6 V, supporting precise dynamic power estimation via PD = CPD × VCC² × fi × N.

FAQ

What is the minimum supply voltage at which 74AUP1G14GW,125 guarantees correct Schmitt-trigger operation?

The device is fully specified down to 0.8 V VCC, with verified VT+ and VT− thresholds, propagation delays, and output drive strength across the entire -40 °C to +125 °C range. At 0.8 V, typical hysteresis is 0.50 V, and tPD remains under 20 ns with CL = 5 pF.

Does 74AUP1G14GW,125 require external pull-up or pull-down resistors on the input or output?

No. The Schmitt-trigger input has no internal bias; however, an external pull-up or pull-down is required only if the source is high-impedance or floating. The CMOS output is push-pull and does not require termination unless driving long traces or transmission lines.

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

IOFF activates automatically when VCC falls below ~0.2 V. During power-up, outputs remain in high-impedance until VCC exceeds the functional threshold (~0.5 V), preventing glitch generation or bus contention. This behavior is tested per JESD78 Class II latch-up standards.

Can 74AUP1G14GW,125 drive a 50 Ω transmission line directly?

Yes. With ±20 mA output drive capability and 3.6 V VCC, the device can deliver >30 mA peak current into short-term loads. For sustained 50 Ω matching, series termination (e.g., 22 Ω) is recommended to limit ringing while maintaining edge rate and noise margin.
