Nexperia USA Inc. 74AUP1G18GS,132

Overview

74AUP1G18GS,132 from Nexperia is a low-power 1-of-2 demultiplexer with 3-state deselected output, operating across 0.8 V to 3.6 V supply. It routes input data (A) to either 1Y or 2Y based on select input (S), while the unselected output enters high-impedance OFF-state. Schmitt-trigger inputs tolerate slow signal edges, and IOFF circuitry prevents backflow current during partial power-down - used in battery-powered sensor interfaces and portable MCU peripheral expansion.

For engineers reviewing the 74AUP1G18GS,132 datasheet, 74AUP1G18GS,132 pinout, 74AUP1G18GS,132 application, or 74AUP1G18GS,132 equivalent, this device supports ultra-low static current (≤1.4 μA at −40 °C to +125 °C), wide-voltage logic interfacing, and robust ESD protection (HBM >5000 V), making it critical for space-constrained, multi-rail embedded systems requiring deterministic signal routing with minimal quiescent power.

Technical Context

The 74AUP1G18GS implements a single-pole double-throw (SPDT) demux function with active-high enable logic via S input, where S = LOW selects 1Y and S = HIGH selects 2Y. All inputs feature Schmitt-trigger thresholds with hysteresis ≥0.1 V at VCC = 1.2 V, enabling reliable operation with noisy or slow-rising signals.

Its IOFF circuit activates when VCC = 0 V, forcing both outputs into high-impedance state regardless of S or A levels, preventing current backflow in hot-swap or mixed-supply domains. The device is characterized across −40 °C to +125 °C and supports dynamic switching up to 300 MHz at VCC = 3.3 V with CL = 5 pF (tpd ≤ 3.5 ns).

FAQ

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

The 74AUP1G18GS,132 supports input voltages up to +4.6 V regardless of VCC level, including VCC = 0 V. This overvoltage tolerance allows safe connection to live buses during power sequencing or hot-swap events without damage or leakage path formation.

Does the device support true bidirectional signal routing?

No - the 74AUP1G18GS,132 is unidirectional: data flows only from input A to outputs 1Y or 2Y. It does not support reverse signal flow (e.g., from 1Y to A). For bidirectional bus switching, consider dedicated analog switches like the NX3L series.

How does the Schmitt-trigger input improve system reliability?

Schmitt-trigger inputs provide ≥0.1 V hysteresis at 1.2 V supply, rejecting noise spikes and slow-edge interference that could cause metastability or false triggering. This eliminates need for external RC filters on long traces or noisy environments like motor-driven industrial enclosures.

Can 74AUP1G18GS,132 drive a 50 pF load reliably?

While characterized up to 30 pF in datasheet timing tables, the device can drive 50 pF loads with increased propagation delay (tpd ≈ 5.2 ns at VCC = 3.3 V). For timing-critical 50 pF applications, verify setup/hold margins in final layout; consider adding a buffer stage if skew exceeds 1 ns.
