Product details
Overview
74AUP1G157GW,125 from Nexperia is a single 2-input CMOS multiplexer with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply, delivering propagation delay as low as 0.9 ns (VCC = 3.0 V, CL = 5 pF), ICC ≤ 0.9 µA max, and IOFF-enabled partial power-down protection. It serves as a low-power signal routing element in battery-powered sensor interfaces and portable logic subsystems.
For engineers reviewing the 74AUP1G157GW,125 datasheet, 74AUP1G157GW,125 pinout, 74AUP1G157GW,125 application, or 74AUP1G157GW,125 equivalent, key selection criteria include its ultra-low static current, rail-to-rail input tolerance up to 3.6 V, guaranteed operation at -40 °C to +125 °C, and TSSOP6 package compatibility with high-density PCB layouts.
Technical Context
The device implements a single-pole double-throw (SPDT) analog/digital multiplexer function with active-high select logic (S = L selects I0; S = H selects I1). Its Schmitt-trigger inputs provide hysteresis of typically 0.1 × VCC, enabling robust operation with slow-rising signals common in microcontroller GPIO or sensor output paths.
All inputs and outputs are overvoltage tolerant to 3.6 V independent of VCC, and the IOFF circuit ensures bidirectional isolation when VCC = 0 V - preventing back-current flow during system power sequencing or hot-swap events in multi-rail embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 0.8 V to 3.6 V - supports direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Max ICC (static) | 0.9 µA at VCC = 3.6 V - enables >10-year battery life in always-on IoT endpoint nodes. |
| tpd (I0/I1/S → Y) | 0.9 ns min / 3.9 ns max (VCC = 3.0 V, CL = 5 pF) - suitable for sub-100 MHz digital control path switching. |
| IOFF leakage | ±0.75 µA max at VCC = 0 V - prevents cross-talk and power loss when upstream/downstream blocks are powered down. |
| Input hysteresis | Typ. 0.1 × VCC - rejects noise on slow-switching lines such as mechanical switch debouncing or thermistor ADC inputs. |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drive control logic. |
| ESD rating (HBM) | 5000 V - exceeds IEC 61000-4-2 Level 3, reducing need for external transient protection in handheld devices. |
Pinout & Package
TSSOP6 plastic thin shrink small outline package (SOT363-2); 6 leads; body width 1.25 mm; exposed pad not present; pin 1 marked by lower-left corner notch below marking code "aP".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I1 | Data input source 1 - selected when S = HIGH; accepts 0–3.6 V regardless of VCC. |
| 2 | GND | Reference ground - must be connected before VCC to avoid latch-up; shared return for all I/O. |
| 3 | I0 | Data input source 0 - selected when S = LOW; Schmitt-triggered for noise immunity. |
| 4 | Y | Multiplexer output - drives CMOS loads up to ±4 mA; maintains valid logic levels across full VCC range. |
| 5 | VCC | Supply voltage - powers internal logic and output stage; IOFF activates when VCC = 0 V. |
| 6 | S | Select control input - active-high; Schmitt-triggered; determines I0 (S = L) or I1 (S = H) routing to Y. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input tolerance | Inputs withstand 0 V to 3.6 V regardless of VCC - eliminates external clamping diodes in mixed-voltage systems. |
| IOFF partial power-down | Output disables and isolates bidirectionally when VCC = 0 V - essential for safe power sequencing in multi-supply SoC peripherals. |
| Ultra-low dynamic power | CPD = 4.0 pF at VCC = 3.3 V - reduces switching power to <1 µW at 1 MHz, critical for energy harvesting designs. |
| Wide temperature qualification | Specified from -40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for automotive body electronics. |
| High noise immunity | Input hysteresis ≥ 0.1 × VCC + low undershoot/overshoot (<10 % of VCC) - suppresses EMI-induced glitches in noisy industrial environments. |
Applications
| Portable Sensor Hub | Automotive Body Control 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 |
|---|---|---|---|
| SN74LVC1G157DBVR | Higher ICC (max 10 µA), no IOFF, VCC min = 1.65 V - lacks true partial power-down and sub-1 V operation. | Not suitable for battery voltage scaling below 1.65 V or systems requiring VCC = 0 V isolation. | Choose only if operating exclusively at 3.3 V and IOFF is unnecessary. |
| 74LVC1G3157GW,125 | Same package and pinout; includes analog switch functionality (break-before-make) but higher Ron (10 Ω vs. <5 Ω typical). | Better for analog signal routing; less optimal for pure digital logic due to higher propagation delay (3.5 ns min). | Select when analog signal integrity matters more than speed or when break-before-make timing is required. |
Compared with SN74LVC1G157DBVR and 74LVC1G3157GW,125, the 74AUP1G157GW,125 uniquely combines sub-1 V operation, IOFF isolation, and lowest static current - making it the only choice for energy-constrained, multi-rail, or automotive-grade signal routing where power sequencing safety is mandatory.

FAQ
Does 74AUP1G157GW,125 support true analog signal switching?
No - it is a digital CMOS multiplexer optimized for logic-level signals. While it can pass analog voltages within 0–3.6 V, it lacks break-before-make timing and has no specified on-resistance or bandwidth; use 74LVC1G3157GW,125 for analog applications requiring controlled switching.
Can I operate 74AUP1G157GW,125 at 0.7 V supply?
No - the absolute minimum recommended VCC is 0.8 V per Table 6. Operation below 0.8 V risks undefined logic states, increased propagation delay variability, and failure to meet VIH/VIL thresholds; design margins require strict adherence to 0.8–3.6 V range.
What happens to the Y output during power-down (VCC = 0 V)?
When VCC = 0 V, the IOFF circuit disables the output driver, placing Y in high-impedance state with leakage ≤ ±0.75 µA - preventing back-current flow from other powered rails connected to Y, satisfying IEC 61000-4-2 system-level isolation requirements.
Is pin 1 orientation consistent across all 74AUP1G157 package variants?
Yes - all variants (GW, GM, GN, GS, GX) locate pin 1 at the lower-left corner beneath the marking code "aP", verified in Figures 6–11 of the datasheet; this allows drop-in substitution in layout when thermal or board-space constraints permit package change.
