Product details
Overview
74AUP1T45GF,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 ↔ 1.8 V or 1.8 V ↔ 3.3 V. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and operates across –40 °C to +125 °C in a 6-pin XSON package. Used in low-power IoT sensor interfaces and mixed-voltage microcontroller I/O expansion.
For engineers reviewing the 74AUP1T45GF,132 datasheet, 74AUP1T45GF,132 pinout, 74AUP1T45GF,132 application, or 74AUP1T45GF,132 equivalent, this device supports critical design tasks including voltage-domain bridging in battery-powered wearables, I²C/SPI signal translation in industrial controllers, and safe I/O isolation during system suspend modes.
Technical Context
The 74AUP1T45GF,132 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 data ports are fully 3-state controllable and tolerate input voltages up to 3.6 V regardless of supply level.
Its IOFF architecture actively disables outputs when either VCC(A) or VCC(B) is at GND, preventing backflow current and ensuring high-impedance OFF-state behavior in suspend mode - a requirement for modern low-power system architectures with asymmetric power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.1 V to 3.6 V per rail - enables interoperability across 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic families |
| Propagation Delay | 1.7 ns to 15.4 ns (CL = 5 pF) - supports >30 MHz data rates in typical mixed-voltage configurations |
| IOFF Leakage | ±0.75 μA max at –40 °C to +125 °C - ensures safe hot-insertion and power-gating without bus contention |
| Static ICC | 1.4 μA max - delivers ultra-low quiescent power for always-on sensor nodes and energy-harvesting systems |
| ESD Rating | HBM >5000 V, CDM >1000 V - meets industrial-grade robustness requirements without external protection |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive, motor control, and industrial PLC applications |
Pinout & Package
74AUP1T45GF,132 is supplied in SOT1115 - a 0.9 × 1.0 × 0.35 mm XSON6 package with no leads and bottom-side thermal pad (not electrically connected). Pin 1 indicator is located on lower-left corner below marking code 'p5'.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply rail for A-port logic and DIR input reference - sets input thresholds and output drive strength for A side |
| 2 | GND | Common ground reference for both supply domains and internal bias networks |
| 3 | A | Bidirectional data terminal referenced to VCC(A); accepts 0–3.6 V inputs independent of VCC(A) level |
| 4 | B | Bidirectional data terminal referenced to VCC(B); drives/receives relative to its own supply domain |
| 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 logic - independently configurable from VCC(A) to enable true dual-voltage operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supplies | VCC(A) and VCC(B) each adjustable 1.1–3.6 V - eliminates need for external level shifters in heterogeneous SoC designs |
| Schmitt-trigger inputs | Hysteresis ≥0.4 V across full VCC range - rejects noise on slow-rising signals from mechanical switches or long PCB traces |
| IOFF partial power-down | Outputs enter high-Z when either VCC is 0 V - prevents back-current damage during staggered power sequencing |
| Low dynamic power | tpd × ICC < 0.1 pJ per transition at 3.3 V - reduces switching noise in sensitive analog/mixed-signal subsystems |
| JEDEC-compliant interfaces | Meets JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), JESD8-B (2.7–3.6 V) - guarantees interoperability with standard logic families |
Applications
| Industrial Sensor Hub | Automotive Body Control Module |

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 |
|---|---|---|---|
| SN74LVC1T45DPWR | Wider VCC range (1.65–5.5 V), higher ICC (10 μA typ), no IOFF circuit | Lacks partial power-down capability - unsuitable for systems requiring hot-swap or asymmetric power sequencing | Select only if 5 V compatibility is required and suspend-mode leakage is not critical |
| TXB0101DCKR | Auto-direction sensing, higher propagation delay (up to 26 ns), larger X2SON package (1.35 × 0.8 mm) | Eliminates DIR pin but adds latency and board space - less predictable timing in synchronous protocols like SPI | Prefer for simple push-button or UART links; avoid for clock-critical I²C or memory-mapped interfaces |
Compared with SN74LVC1T45DPWR and TXB0101DCKR, the 74AUP1T45GF,132 uniquely combines sub-μA static current, guaranteed IOFF behavior, and minimal 0.9 × 1.0 mm footprint - making it optimal for space-constrained, battery-operated, and thermally sensitive applications demanding deterministic low-power operation.

FAQ
Can 74AUP1T45GF,132 translate between 1.2 V and 5 V logic levels?
No. The absolute maximum VCC rating is +4.6 V, and recommended operation caps VCC(A)/VCC(B) at 3.6 V. Driving a 5 V bus risks exceeding voltage limits on B-port outputs and violates JEDEC compliance. For 1.2 V ↔ 5 V translation, use a dedicated high-voltage translator like TXS0108E with appropriate clamping.
What happens to the A and B ports when VCC(A) = 0 V and VCC(B) = 3.3 V?
Both A and B ports enter high-impedance OFF-state due to IOFF circuit activation. Measured OFF-state leakage is ≤±0.75 μA at +125 °C, preventing back-current flow into the powered B-side domain - a key safety feature during power sequencing or fault conditions.
Does DIR input require a pull-up or pull-down resistor?
No. DIR has defined VIH/VIL thresholds referenced to VCC(A): VIH ≥0.7×VCC(A), VIL ≤0.3×VCC(A). With VCC(A) = 1.8 V, DIR is guaranteed HIGH above 1.26 V and LOW below 0.54 V - sufficient noise margin to drive directly from CMOS outputs without external biasing.
Is the SOT1115 package compatible with reflow soldering per IPC-J-STD-020?
Yes. The SOT1115 (XSON6) package is qualified for standard lead-free reflow profiles with peak temperature ≤260 °C. Its 0.35 mm height and thermal pad design support uniform heating and void-free solder joints when using recommended stencil aperture (0.25 mm thickness, 0.7 × 0.9 mm opening) and nitrogen atmosphere.
