Nexperia USA Inc. 74AUP2G125GS,115

Overview

74AUP2G125GS,115 from Nexperia is a dual 3-state buffer/line driver with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply, delivering ICC ≤ 1.4 μA (max at −40 °C to +125 °C), tpd ≤ 4.4 ns (VCC = 3.3 V, CL = 5 pF), and IOFF-enabled partial power-down protection. It serves in low-power I/O expansion, voltage-level translation, and bus isolation in portable and industrial control systems.

For engineers reviewing the 74AUP2G125GS,115 datasheet, 74AUP2G125GS,115 pinout, 74AUP2G125GS,115 application, or 74AUP2G125GS,115 equivalent, key selection criteria include ultra-low static current, guaranteed 3-state output disable under VCC = 0 V, Schmitt-trigger noise immunity, and XSON8 (SOT1203) package compatibility with high-density PCB layouts.

Technical Context

The device implements two independent non-inverting buffers, each with active-low 3-state enable (1OE, 2OE) and Schmitt-trigger input thresholds (VIH/VIL varying by VCC). Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V while inputs/outputs remain biased up to 3.6 V.

Dynamic performance is characterized by propagation delay (tpd), enable time (ten), and disable time (tdis), all specified across VCC = 0.8 V–3.6 V and temperature (−40 °C to +125 °C), with load capacitance dependencies (CL = 5–30 pF) explicitly tabulated for design margining.

FAQ

What is the maximum allowable input voltage when VCC = 0 V?

The 74AUP2G125GS,115 supports overvoltage-tolerant inputs up to 3.6 V regardless of VCC state. When VCC = 0 V, VI may safely reach 3.6 V without damage or excessive leakage, enabling hot-plug capability in modular systems where subsystems power up asynchronously.

Does this device support mixed-voltage interfacing between 1.8 V and 3.3 V domains?

Yes. With VCC = 1.8 V, inputs accept VIH ≥ 1.17 V and VIL ≤ 0.54 V, while outputs drive VOH ≥ 1.6 V and VOL ≤ 0.35 V into 1.8 V loads. At VCC = 3.3 V, it drives 3.3 V logic levels and tolerates 1.8 V inputs directly-enabling seamless bidirectional level translation without external resistors.

How does the Schmitt-trigger input improve noise immunity in real-world layouts?

Schmitt-trigger inputs provide ≥100 mV hysteresis, rejecting noise spikes <100 mV and preventing multiple transitions on slow-rising signals (e.g., from RC-filtered sensors or long traces). This eliminates need for external RC filtering or software debouncing in industrial control inputs subject to EFT or conducted emissions.

Can the 74AUP2G125GS,115 be used in place of older 74AHC or 74LV families?

It can replace them in low-power applications but requires validation of timing margins: propagation delay is longer than 74AHC (e.g., 4.4 ns vs. ~3 ns at 3.3 V), and drive strength is lower (±20 mA vs. ±25 mA). Use only where ultra-low ICC and IOFF outweigh speed requirements-never as direct drop-in for high-speed clock distribution.
