Nexperia USA Inc. 74AUP1G18GM,132

Overview

74AUP1G18GM,132 from Nexperia is a low-power 1-of-2 demultiplexer with 3-state deselected outputs, designed for signal routing in ultra-low-voltage digital systems. It buffers input A and routes it to 1Y (S = LOW) or 2Y (S = HIGH), while the inactive output enters high-impedance OFF-state. Features Schmitt-trigger inputs, IOFF partial power-down protection, and operation from 0.8 V to 3.6 V supply - used in battery-powered IoT sensor nodes and portable MCU peripheral expansion.

For engineers reviewing the 74AUP1G18GM,132 datasheet, 74AUP1G18GM,132 pinout, 74AUP1G18GM,132 application, or 74AUP1G18GM,132 equivalent, key selection criteria include its 0.9 μA max ICC at 125 °C, 3.6 ns propagation delay at 3.3 V/CL = 5 pF, IOFF-enabled safe power sequencing, and XSON6 (SOT886) 1 × 1.45 × 0.5 mm package for space-constrained PCB layouts.

Technical Context

The device implements a single-pole double-throw (SPDT) logic-controlled signal switch using CMOS AUP technology. Its Schmitt-trigger inputs tolerate slow-rising signals up to 200 ns/V transition rate, enabling robust interfacing with mechanical switches or noisy microcontroller GPIOs.

IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for multi-rail systems where peripherals power down before the host MCU. The 3-state outputs support bus sharing without external pull-ups or contention.

FAQ

What is the maximum capacitive load the 74AUP1G18GM,132 can drive while maintaining specified tpd?

The device is characterized up to CL = 30 pF across all VCC and temperature conditions. At VCC = 3.3 V and Tamb = 25 °C, tpd remains ≤5.8 ns with 30 pF load. Driving >30 pF may increase propagation delay nonlinearly and degrade edge integrity due to increased slew rate limitations - verify timing margins in final layout with IBIS simulation.

Can the 74AUP1G18GM,132 safely interface between a 1.2 V MCU and a 3.3 V sensor without external level shifters?

Yes. Inputs tolerate up to 3.6 V regardless of VCC, and outputs swing rail-to-rail (VOH ≥ VCC − 0.1 V, VOL ≤ 0.11 V). With VCC = 1.2 V, it accepts 3.3 V sensor signals directly, and drives 1.2 V MCU inputs with full logic margin - no level shifter needed for this cross-voltage direction.

Does the IOFF feature activate automatically when VCC drops below a threshold, or must it be controlled externally?

IOFF activates automatically when VCC = 0 V - no external control required. The circuit detects VCC loss and disables outputs within nanoseconds, preventing backflow current. It remains active as long as VCC is near 0 V (≤0.2 V), with ΔIOFF ≤ ±0.75 μA. No enable/disable pin or configuration is needed.

How does the Schmitt-trigger input improve reliability in noisy industrial environments?

Schmitt action provides ≥100 mV hysteresis at 1.0 V supply, meaning a rising input must exceed VIH by >100 mV to register HIGH, and falling input must drop below VIL by >100 mV to register LOW. This rejects transient noise spikes <100 mV amplitude - critical for reliable operation near motors, solenoids, or switching power supplies without added RC filtering.
