Nexperia USA Inc. 74AUP1G157GM-Q100X

Overview

74AUP1G157GM-Q100 from Nexperia is a single 2-input CMOS multiplexer with Schmitt-trigger inputs, designed for signal routing in low-voltage automotive control modules. It operates across 0.8 V to 3.6 V, delivers propagation delay as low as 1.2 ns (VCC = 3.3 V, CL = 5 pF), supports partial power-down via IOFF, and is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C).

For engineers reviewing the 74AUP1G157GM-Q100 datasheet, 74AUP1G157GM-Q100 pinout, 74AUP1G157GM-Q100 application, or 74AUP1G157GM-Q100 equivalent, this page provides verified functional role, automotive-grade thermal and voltage margins, IOFF-enabled system-level power sequencing, and direct pin-to-function mapping for layout validation.

Technical Context

This device implements a single-pole double-throw (SPDT) analog/digital signal selector using standard CMOS logic with Schmitt-trigger input buffers-enabling robust operation with slow-rising or noisy control signals (S input) and data sources (I0/I1). The IOFF circuit actively disables output Y and isolates I/O terminals when VCC = 0 V, preventing back-current during hot-swap or multi-rail power sequencing.

Its ultra-low static current (ICC ≤ 1.4 µA max at −40 °C to +125 °C) and dynamic power dissipation capacitance (CPD = 4.0 pF at VCC = 3.3 V) make it suitable for always-on vehicle subsystems such as body control modules and sensor interface hubs where standby leakage and switching energy must be minimized.

FAQ

Can the 74AUP1G157GM-Q100 operate reliably at 0.85 V supply?

Yes. The device is fully characterized down to 0.8 V, with guaranteed VIH ≥ 0.70 × VCC and VOL ≤ 0.11 V at VCC = 0.85 V and IO = 20 µA. Propagation delay remains within 12.6 ns (max) at CL = 5 pF, supporting low-voltage microcontroller interfaces in battery-critical applications.

Does the IOFF feature protect against back-current when only VCC is unpowered but I/O pins remain biased?

Yes. When VCC = 0 V, the IOFF circuit disables both output Y and input buffers, limiting leakage to ±0.75 µA maximum even if I0, I1, S, or Y are held at voltages up to 3.6 V - satisfying JESD78 Class II latch-up immunity and preventing damage during hot-plug scenarios.

What is the maximum capacitive load the output can drive while maintaining specified timing?

The device is characterized up to CL = 30 pF, with tpd ≤ 7.1 ns (max) at VCC = 3.3 V. Driving loads beyond 30 pF increases propagation delay nonlinearly and may violate setup/hold timing in synchronous systems; for >30 pF, add series termination or buffer stage.

Is the Schmitt-trigger hysteresis adjustable or fixed?

Fixed. The hysteresis is inherent to the input stage design and not user-configurable; typical threshold separation is ~100 mV at VCC = 3.3 V, providing consistent noise margin across temperature and voltage without external components.
