Nexperia USA Inc. 74AUP1G240GN,132

Overview

74AUP1G240GN,132 from Nexperia is a single-channel low-power inverting buffer/line driver with 3-state output and Schmitt-trigger inputs, operating from 0.8 V to 3.6 V supply. It features output enable (OE) control, IOFF partial power-down protection, and supports industrial temperature range (−40 °C to +125 °C). Used in voltage-level translation and bus isolation in portable IoT sensors and ultra-low-power microcontroller I/O expansion.

For engineers reviewing the 74AUP1G240GN,132 datasheet, 74AUP1G240GN,132 pinout, 74AUP1G240GN,132 application, or 74AUP1G240GN,132 equivalent, key selection criteria include its 0.9 μA max ICC at 3.6 V, 3.6 ns max tpd at VCC = 3.3 V/CL = 5 pF, Schmitt-trigger noise immunity, IOFF leakage < ±0.75 μA at VCC = 0 V, and XSON6 (SOT1115) 0.9 × 1.0 × 0.35 mm package.

Technical Context

This device implements a single inverting logic gate with tristate output controlled by an active-low OE input. Its Schmitt-trigger inputs tolerate slow-rising signals and reject noise up to 30 % of VCC hysteresis, enabling robust operation in noisy mixed-signal environments.

The IOFF circuit actively disables outputs during power-down, blocking backflow current even when input/output pins are biased at 3.6 V while VCC = 0 V - critical for hot-swap and multi-rail system interoperability.

FAQ

What is the maximum output drive strength of the 74AUP1G240GN,132 at 3.3 V?

The device delivers ±4.0 mA output current at VCC = 3.0 V, with VOL ≤ 0.45 V and VOH ≥ 2.55 V under those conditions. This supports direct driving of standard CMOS loads and short PCB traces without external buffers, though fan-out should be limited to ≤10 LS TTL loads for guaranteed timing margins.

Can the 74AUP1G240GN,132 operate reliably at 0.8 V supply?

Yes - it is fully specified from 0.8 V to 3.6 V, with propagation delay ≤22.3 ns (CL = 5 pF) and ICC ≤1.4 μA at VCC = 0.8 V and −40 °C to +125 °C. Input thresholds scale with VCC (VIH ≥ 0.75 × VCC), ensuring correct logic interpretation across the entire range.

Does the 'n.c.' pin on the SOT1115 package require PCB routing or grounding?

No - Pin 5 is internally unconnected and must remain floating on the PCB. No trace, pad, or solder mask opening is needed; routing to GND or VCC would violate the device's electrical specification and may cause parametric failure or increased leakage.

How does the IOFF feature protect the device during partial power-down?

When VCC = 0 V, the IOFF circuit disables both input and output structures, limiting VI/O leakage to ±0.75 μA even if external voltages up to 3.6 V are applied to A, Y, or OE pins. This prevents reverse current flow into the unpowered die, avoiding latch-up and enabling safe hot-swap in modular systems.
