Product details
Overview
74AUP1T45GM,132 from Nexperia is a single-bit dual-supply translating transceiver with independent VCC(A) and VCC(B) rails (1.1 V to 3.6 V), enabling bidirectional level translation between mismatched logic domains such as 1.2 V ↔ 3.3 V or 1.8 V ↔ 2.5 V. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and operates across –40 °C to +125 °C. Used in low-power portable and industrial interface bridging.
For engineers reviewing the 74AUP1T45GM,132 datasheet, 74AUP1T45GM,132 pinout, 74AUP1T45GM,132 application, or 74AUP1T45GM,132 equivalent, key selection criteria include dual-rail voltage flexibility, sub-1 μA static ICC, IOFF-enabled hot-swap safety, and XSON6 package suitability for space-constrained PCB layouts.
Technical Context
The device implements a direction-controlled bidirectional data path where DIR input (referenced to VCC(A)) selects A→B (DIR = HIGH) or B→A (DIR = LOW). Both A and B ports are 3-state capable with independent supply referencing: A and DIR tie to VCC(A), while B ties to VCC(B).
Its IOFF circuit actively disables outputs when either VCC(A) or VCC(B) is at GND, limiting backflow current to ±0.75 μA and forcing both ports into high-impedance OFF-state during suspend mode - critical for mixed-voltage system power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) / VCC(B) Range | 1.1 V to 3.6 V each - enables interoperability across 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic families |
| ICC (max) | 1.4 μA at –40 °C to +125 °C - ensures ultra-low static power in battery-backed or always-on subsystems |
| tpd (A↔B) | 1.7 ns to 28.0 ns (CL = 5 pF) - supports signal integrity up to ~100 MHz in short-trace interconnects |
| IOFF Leakage | ±0.75 μA max - prevents damaging current flow during partial power-down or hot insertion |
| Operating Temp | –40 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
| ESD Robustness | HBM > 5000 V, CDM > 1000 V - reduces need for external protection in handheld and I/O-exposed designs |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); no leads; 6-terminal surface-mount; body size 1.0 × 1.45 × 0.5 mm; wettable flank option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply rail for A port and DIR input - defines logic thresholds and drive strength for A-side signals |
| 2 | GND | Common reference ground for both supply domains - mandatory connection for stable biasing |
| 3 | A | Bidirectional data terminal referenced to VCC(A) - connects to 1.1–3.6 V domain A (e.g., MCU I/O) |
| 4 | B | Bidirectional data terminal referenced to VCC(B) - connects to separate 1.1–3.6 V domain B (e.g., sensor interface) |
| 5 | DIR | Direction control input referenced to VCC(A) - HIGH enables A→B, LOW enables B→A |
| 6 | VCC(B) | Supply rail for B port - independently configurable to match target domain voltage |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) each adjustable 1.1–3.6 V - eliminates need for external level-shifting ICs in heterogeneous SoC interfaces |
| Schmitt-trigger inputs | Hysteresis on A, B, and DIR pins - tolerates slow-rising signals and improves noise margin in noisy industrial environments |
| IOFF partial power-down | Automatic high-Z output disable when either VCC is at GND - enables safe live insertion and power sequencing in modular systems |
| Ultra-low ICC | Max 1.4 μA over full temperature range - extends battery life in IoT edge nodes and wearable sensors |
| Small-footprint XSON6 | 1.0 × 1.45 mm body with wettable flanks - supports automated optical inspection (AOI) and high-density routing in compact PCBs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | 2-channel, fixed 1.2–3.6 V translation; no DIR pin - auto-direction sensing via bus activity | Requires active bus traffic to detect direction; unsuitable for static control lines or low-duty-cycle interfaces | Select when bidirectional data flow is continuous and deterministic; avoid for control/status lines with infrequent updates |
| SN74LVC1T45DCKR | Single-bit, dual-supply; identical DIR control but higher ICC (max 10 μA) and wider temp range (–40 °C to +125 °C same) | Larger SOT-23-6 package (2.9 × 1.6 mm vs. XSON6's 1.0 × 1.45 mm) - limits high-density layout options | Prefer when existing footprint compatibility with LVC family is required; accept trade-off in board area and quiescent power |
Compared with TXS0102DCUR and SN74LVC1T45DCKR, the 74AUP1T45GM,132 delivers the lowest static power (1.4 μA), smallest footprint (XSON6), and explicit DIR control - making it optimal for space- and energy-constrained embedded systems requiring deterministic direction management.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet specifies independent operation from 1.1 V to 3.6 V per rail, with no absolute limit stated on differential voltage. However, absolute maximum ratings cap each supply at –0.5 V to +4.6 V relative to GND. Therefore, the practical differential is bounded by those limits - e.g., VCC(A) = 3.6 V and VCC(B) = 1.1 V is valid, but VCC(A) = 4.6 V and VCC(B) = 1.1 V violates VCC(A)'s absolute max and must be avoided.
Does the 74AUP1T45GM,132 support hot-swap without external protection?
Yes - its integrated IOFF circuit automatically places both A and B ports in high-impedance state when either VCC(A) or VCC(B) drops to GND or near-zero, limiting backflow current to ±0.75 μA. This enables safe hot insertion into live backplanes or modular systems without external FETs or diodes, provided supply sequencing respects the device's absolute maximum ratings.
Can DIR be driven from a different voltage domain than VCC(A)?
No - the DIR input is explicitly referenced to VCC(A), and its VIH/VIL thresholds scale with VCC(A) (e.g., VIH ≥ 0.7 × VCC(A)). Driving DIR from a voltage outside the VCC(A) domain risks undefined logic states or excessive input leakage. The control signal must originate from the same supply domain as VCC(A), typically the A-side controller.
Is the XSON6 package (SOT886) compatible with standard reflow profiles?
Yes - the 74AUP1T45GM,132 in SOT886 meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1), allowing unlimited floor life at ≤30 °C/60% RH. Its lead-free terminations and thermal profile tolerance support standard Pb-free reflow (peak 260 °C, 20–40 sec above 217 °C), and the wettable flank variant enables reliable solder joint inspection using AOI systems.
