Product details
Overview
74AUP2G157GS,115 from Nexperia is a low-power 2-input multiplexer IC with true and complement outputs (Y/Y), active-low enable (E), and Schmitt-trigger inputs for noise immunity across 0.8 V–3.6 V supply. It operates from –40 °C to +125 °C, delivers propagation delay as low as 1.0 ns at 3.6 V (CL = 5 pF), and features IOFF partial power-down protection. It is used in battery-powered sensor interfaces and voltage-level-agnostic signal routing in portable IoT nodes.
For engineers reviewing the 74AUP2G157GS,115 datasheet, 74AUP2G157GS,115 pinout, 74AUP2G157GS,115 application, or 74AUP2G157GS,115 equivalent, key selection criteria include ultra-low ICC (≤1.4 μA max), dual-output logic state integrity, Schmitt-trigger input hysteresis, and XSON8 package compatibility with high-density PCB layouts.
Technical Context
This device implements a single-pole double-throw (SPDT) analog/digital multiplexer function using CMOS logic, where the S input selects between I0 and I1, while E enables or disables both outputs simultaneously. The complementary Y/Y outputs provide simultaneous true and inverted data paths without external inverters.
Its IOFF circuitry ensures bidirectional isolation when VCC = 0 V, blocking backflow current up to ±0.75 μA, and Schmitt-trigger inputs maintain clean switching with input rise/fall rates up to 200 ns/V - critical for noisy industrial or automotive sensor bus environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 0.8 V to 3.6 V - supports direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Max ICC (Static) | 1.4 μA at –40 °C to +125 °C - enables multi-year operation in coin-cell–powered edge sensors. |
| Propagation Delay (tpd) | 1.0 ns (min) at VCC = 3.6 V, CL = 5 pF - suitable for sub-500 MHz data path selection in timing-critical control loops. |
| IOFF Leakage | ±0.75 μA at VCC = 0 V - prevents cross-talk and power rail contamination during hot-swap or partial system shutdown. |
| Input Hysteresis | Typical 100 mV (Schmitt-trigger) - rejects <10 % VCC noise on S, E, I0, and I1 inputs across full VCC range. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
| ESD Robustness | HBM >5000 V, CDM >1000 V - survives handling and board-level transient events without shielding. |
Pinout & Package
XSON8 package (SOT1203): extremely thin small outline, no leads, 8-terminal surface-mount, body size 1.35 mm × 1.0 mm × 0.35 mm, wettable flank compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I0 | Data input source 0 - routed to Y/Y when S = LOW and E = LOW. |
| 2 | I1 | Data input source 1 - routed to Y/Y when S = HIGH and E = LOW. |
| 3 | Y | True output - reflects selected input (I0 or I1) when E = LOW; forced LOW when E = HIGH. |
| 4 | GND | Ground reference - must be low-impedance connection to minimize ground bounce in high-speed switching. |
| 5 | Y | Complement output - inverse of Y; HIGH when Y is LOW and vice versa, enabling differential signaling or latch-free logic. |
| 6 | S | Data select input - controls I0/I1 routing; Schmitt-triggered for noise margin up to 100 mV. |
| 7 | E | Enable input (active LOW) - disables both outputs (Y = LOW, Y = HIGH) when HIGH, supporting power-gating. |
| 8 | VCC | Supply voltage - decoupling capacitor (100 nF) required within 2 mm for stable 3.6 V operation at 200 MHz toggle rate. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 1.4 μA over full temperature range - eliminates need for power gating in always-on wake-up circuits. |
| Dual true/complement outputs | Y and Y outputs available simultaneously - removes external inverter, saving board space and propagation delay in feedback paths. |
| IOFF partial power-down | Blocks backflow current when VCC = 0 V - enables safe insertion/removal in live-backplane systems and modular sensor hubs. |
| Wide VCC compatibility | Operates from 0.8 V to 3.6 V - interoperable with legacy 1.2 V ASICs, modern 1.8 V FPGAs, and 3.3 V microcontrollers. |
| High-noise-immunity inputs | Schmitt-trigger thresholds with ≥100 mV hysteresis - tolerates slow-rising signals from thermistors, potentiometers, or long traces. |
Applications
| Battery-Powered Sensor Hub | Industrial PLC I/O Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G157DCUR | Higher ICC (max 10 μA), no IOFF, wider VCC (1.65–5.5 V), same XSON8 pinout. | Lacks power-down isolation; unsuitable for hot-swap or mixed-voltage partial shutdown. | Prefer when interfacing with 5 V logic and IOFF is not required. |
| 74LVC1G157GW,125 | Single-output (Y only), no complement output, identical VCC/IOFF specs, smaller XSON6 (6-pin) package. | Requires external inverter for complement logic; saves 0.25 mm² but increases component count. | Choose when board space is constrained and Y-only output suffices. |
Compared with SN74LVC2G157DCUR and 74LVC1G157GW,125, the 74AUP2G157GS,115 uniquely combines ultra-low ICC, dual true/complement outputs, and IOFF in XSON8 - making it optimal for energy-constrained, fault-tolerant, and mixed-voltage designs where signal integrity and power-state coordination are critical.

FAQ
What is the maximum recommended load capacitance for stable operation?
The 74AUP2G157GS,115 is characterized up to 30 pF load capacitance per output (Y or Y). At VCC = 3.6 V and CL = 30 pF, tpd remains ≤7.3 ns. For loads >30 pF, propagation delay increases linearly and output drive strength may degrade; external buffering is advised beyond 50 pF.
Can the 74AUP2G157GS,115 interface directly with 5 V logic inputs?
No. Inputs tolerate up to 3.6 V absolute maximum, and VIH/VIL thresholds scale with VCC (e.g., VIH ≈ 2.0 V at VCC = 3.0 V). Direct 5 V input risks damage and violates JEDEC JESD8-B compliance. A level translator such as TXB0102 is required for 5 V ↔ 3.3 V interfacing.
How does the IOFF feature behave when VCC is ramping during power-up?
IOFF activates when VCC drops below ~0.2 V and remains active until VCC exceeds ~0.5 V. During power-up, outputs stay isolated until VCC stabilizes above the functional threshold (~0.8 V), preventing metastable states or bus contention in multi-rail systems.
Is the Y/Y output pair guaranteed to switch simultaneously?
Yes. Propagation delays tPLH and tPHL are matched within ±0.2 ns (typical) across all VCC and temperature conditions. The internal layout and symmetric driver design ensure <100 ps skew between Y and Y transitions, critical for clockless handshake protocols.
