Nexperia USA Inc. 74AUP1G157GN,132

Overview

74AUP1G157GN,132 from Nexperia is a single 2-input CMOS multiplexer with Schmitt-trigger inputs, operating from 0.8 V to 3.6 V supply, featuring IOFF partial power-down protection, <0.9 µA max static ICC, and −40 °C to +125 °C temperature range - used in low-power signal routing for battery-powered sensor interfaces and portable logic subsystems.

For engineers reviewing the 74AUP1G157GN,132 datasheet, 74AUP1G157GN,132 pinout, 74AUP1G157GN,132 application, or 74AUP1G157GN,132 equivalent, key selection criteria include its ultra-low static current, overvoltage-tolerant 3.6 V inputs at sub-1 V VCC, IOFF-enabled bus hold during power sequencing, and guaranteed propagation delay ≤3.9 ns at 3.0–3.6 V with 5 pF load.

Technical Context

This device implements a single-pole double-throw (SPDT) analog/digital multiplexer function using standard CMOS transmission gates controlled by a single select input (S), with all inputs buffered by Schmitt-trigger circuitry to tolerate slow-rising signals and improve noise immunity. The IOFF feature actively disables output leakage when VCC = 0 V, preventing backflow current in partial power-down systems.

It complies with JEDEC standards across five voltage bands (JESD8-12 through JESD8C), supports latch-up immunity >100 mA per JESD78 Class II, and delivers rail-to-rail output swing with VOH ≥2.3 V and VOL ≤0.5 V under 4 mA load at VCC = 3.0 V.

FAQ

Can 74AUP1G157GN,132 operate with VCC = 0.8 V while accepting 3.3 V inputs?

Yes. Its inputs are overvoltage tolerant up to 3.6 V independent of VCC level, and all DC specifications - including VIH/VIL thresholds and output drive strength - are guaranteed down to VCC = 0.8 V. This enables safe interfacing between legacy 3.3 V peripherals and next-generation sub-1 V MCUs without external level translation.

What happens to the Y output when VCC = 0 V and IOFF is active?

When VCC drops to 0 V, the IOFF circuitry disables the output stage, placing Y in a high-impedance state with leakage current limited to ±0.75 µA. This prevents back-driving of upstream circuits or loading of downstream buses, supporting safe power sequencing in multi-rail systems such as USB-C PD adapters or modular instrumentation.

Is the Schmitt-trigger hysteresis adjustable or fixed?

The hysteresis is fixed and internally set - typically ≥0.1 × VCC - and applies to all three inputs (I0, I1, and S). It is not user-configurable but ensures consistent noise rejection across the full 0.8–3.6 V VCC range and −40 °C to +125 °C temperature span without external components.

How does propagation delay vary with load capacitance and supply voltage?

Propagation delay increases linearly with load capacitance: at VCC = 3.0–3.6 V, tpd is 3.2 ns (max) for CL = 5 pF, rising to 6.0 ns (max) for CL = 30 pF. Lower VCC increases delay - e.g., at VCC = 1.65 V and CL = 5 pF, tpd reaches 6.4 ns (max). These values are fully characterized and guaranteed in the datasheet across all operating conditions.
