Product details
Overview
74AUP1G18GW,125 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 inactive output enters high-impedance OFF-state. Features Schmitt-trigger inputs, IOFF partial power-down protection, and -40 °C to +125 °C operation - used in battery-powered sensor interfaces and portable logic level translation.
For engineers reviewing the 74AUP1G18GW,125 datasheet, 74AUP1G18GW,125 pinout, 74AUP1G18GW,125 application, or 74AUP1G18GW,125 equivalent, key selection criteria include ultra-low ICC (≤1.4 μA), 3-state output control timing (tdis ≤7.6 ns at VCC = 3.6 V), Schmitt-trigger noise immunity, and TSSOP6 package compatibility with space-constrained PCB layouts.
Technical Context
The device implements a single-pole double-throw (SPDT) signal routing function using complementary CMOS logic, with independent enable/disable control per output via the S input. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±0.75 μA.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 × VCC) for robust operation with slow-rising signals, while propagation delays scale predictably with supply voltage and load capacitance - tpd = 1.4 ns (min) at VCC = 3.6 V, CL = 5 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| Max ICC (VCC = 0.8–3.6 V) | 1.4 μA at -40 °C to +125 °C - ensures <1 μW static power at 1.8 V, critical for always-on IoT nodes |
| IOFF Leakage (VCC = 0 V) | ±0.75 μA - prevents damaging back-current during hot-swap or partial system power-down |
| tPD (A→nY, VCC = 3.6 V) | 1.4 ns (min) to 3.5 ns (max) at CL = 5 pF - supports >200 MHz toggle rates in low-capacitance paths |
| VIL / VIH Thresholds | VIL ≤ 0.3 × VCC, VIH ≥ 0.7 × VCC (at VCC = 1.4 V) - provides >400 mV noise margin under worst-case temp/voltage |
| Output Drive (VOH/VOL) | VOH ≥ 2.3 V, VOL ≤ 0.5 V at IO = ±4 mA, VCC = 3.0 V - ensures TTL/CMOS-compatible logic levels |
| ESD Rating (HBM) | ≥5000 V - exceeds IEC 61000-4-2 Level 4 for board-level ESD robustness |
Pinout & Package
TSSOP6 package (SOT363-2): plastic thin shrink small outline, 6-pin, 1.25 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Select input (S) | Controls routing path: S = LOW → A → 1Y; S = HIGH → A → 2Y; unused output goes to high-Z |
| 2 | Ground (GND) | Reference node for all input/output thresholds and internal biasing; must be low-inductance connection |
| 3 | Data input (A) | Buffered input signal source; accepts 0 V to VCC levels with Schmitt-trigger hysteresis |
| 4 | Data output (2Y) | Active-output terminal when S = HIGH; high-impedance when S = LOW |
| 5 | Supply voltage (VCC) | Power rail for core logic and output drivers; supports decoupling with 100 nF ceramic near pin |
| 6 | Data output (1Y) | Active-output terminal when S = LOW; high-impedance when S = HIGH |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 1.4 μA over full temperature range - eliminates need for power gating in energy-harvesting systems |
| IOFF partial power-down | Blocks bidirectional current flow when VCC = 0 V - enables safe insertion into live backplanes or mixed-voltage subsystems |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 × VCC - rejects noise on long traces or mechanical switch inputs without external RC filtering |
| Wide VCC compatibility | Operates from 0.8 V (sub-threshold logic) to 3.6 V (3.3 V I/O) - supports multi-rail SoC interconnects |
| High-temperature rating | Specified from -40 °C to +125 °C - suitable for under-hood automotive modules and industrial motor controls |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1-of-2 demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G18DBVR | Higher ICC (10 μA typ), no IOFF, 1.65–5.5 V range, SOT-23-6 package | Lacks power-down isolation; unsuitable for hot-swap or partial-power systems | Choose when higher drive strength (24 mA) is required and full-system power cycling is guaranteed |
| 74LVC1G18GW,125 | Same pinout and footprint, but higher ICC (10 μA max), no Schmitt-trigger inputs, 1.65–5.5 V only | Lower noise immunity; cannot interface directly with sub-1.65 V logic or slow-switching sensors | Choose only if legacy LVC family compatibility is mandatory and 0.8 V operation is unnecessary |
Compared with SN74LVC1G18DBVR and 74LVC1G18GW,125, the 74AUP1G18GW,125 delivers superior energy efficiency (<1.4 μA vs. >10 μA), true partial-power-down capability, and wider voltage flexibility - making it optimal for battery-critical and thermally constrained designs where signal integrity and leakage control are prioritized over raw drive strength.

FAQ
What is the maximum recommended load capacitance for reliable 74AUP1G18GW,125 operation?
The device is characterized up to 30 pF load capacitance in datasheet Table 8. At CL = 30 pF and VCC = 3.6 V, tpd remains ≤7.0 ns and tdis ≤12.1 ns - within specification. Exceeding 30 pF increases propagation delay nonlinearly and may cause timing violations in high-speed sampling systems; external series termination or reduced slew rate may be needed beyond this limit.
Does the 74AUP1G18GW,125 support mixed-voltage operation between input and output rails?
No. The 74AUP1G18GW,125 has a single VCC pin powering both input buffers and output drivers. Inputs tolerate up to 3.6 V regardless of VCC (overvoltage tolerant), but outputs swing only between GND and the applied VCC. True level-shifting requires separate voltage domain isolation or dedicated translators like NXSL1T22.
How does the IOFF feature behave when VCC is ramping during power-up?
IOFF activates when VCC falls below ~0.2 V and remains active until VCC rises above ~0.5 V. During power-up, outputs stay in high-impedance until VCC crosses the functional threshold (~0.8 V), preventing glitch-induced current spikes or bus contention. This behavior is verified per JESD78 Class II latch-up testing and documented in Section 1.1 of the datasheet.
Can the 74AUP1G18GW,125 be used as a 2-to-1 multiplexer?
Yes - by connecting two data sources to 1Y and 2Y, tying S to control logic, and using A as the common output. However, note that both outputs are 3-state, so only one may be enabled at a time. The truth table (Table 4) confirms this inversion-free configuration yields standard 2:1 MUX behavior with no additional components required.
