Product details
Overview
74AUP1T45GS,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 industrial and automotive systems.
For engineers reviewing the 74AUP1T45GS,132 datasheet, 74AUP1T45GS,132 pinout, 74AUP1T45GS,132 application, or 74AUP1T45GS,132 equivalent, this device supports low-power inter-IC communication where voltage domain isolation, suspend-mode safety, and sub-1 μA static current are critical design requirements.
Technical Context
The 74AUP1T45GS implements a direction-controlled bidirectional data path: DIR = HIGH enables A→B translation; DIR = LOW enables B→A translation. Both I/O ports (A and B) are referenced to their respective supply rails (VCC(A) and VCC(B)), eliminating need for external level-shifting components.
Schmitt-trigger inputs on all pins ensure robust operation with slow-rising signals across full supply range. The IOFF circuit actively disables outputs during power-down, limiting backflow current to ±0.75 μA when either VCC rail is at 0 V - a key requirement for hot-swap and multi-rail power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) / VCC(B) Range | 1.1 V to 3.6 V each - supports mixed-voltage interfaces without external translators |
| ICC (max) | 1.4 μA at –40 °C to +125 °C - enables always-on system monitoring with negligible battery drain |
| tpd (A↔B) | 1.7 ns to 31.2 ns depending on VCC and load - meets timing budgets for 10–50 MHz digital control links |
| IOFF Leakage | ±0.75 μA max when one VCC = 0 V - prevents damage during asymmetric power-up/down sequences |
| ESD Rating | HBM >5000 V, CDM >1000 V - suitable for handling in non-ESD-protected assembly environments |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive and industrial motor-control applications |
| Input Hysteresis | Schmitt-trigger action on all inputs - tolerates >10 ns input rise/fall time degradation without metastability |
Pinout & Package
XSON6 package (SOT1202): 1.0 mm × 1.0 mm × 0.35 mm body, no leads, bottom thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply reference for A port and DIR input - defines logic thresholds for A-side signals |
| 2 | GND | Common ground return for both supply domains - mandatory for noise margin integrity |
| 3 | A | Bidirectional data terminal referenced to VCC(A) - connects to 1.2 V/1.5 V/1.8 V logic |
| 4 | B | Bidirectional data terminal referenced to VCC(B) - connects to 1.8 V/2.5 V/3.3 V logic |
| 5 | DIR | Direction control input referenced to VCC(A) - HIGH = A→B, LOW = B→A |
| 6 | VCC(B) | Supply reference for B port - enables independent voltage domain translation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) operate independently from 1.1 V to 3.6 V - eliminates need for external LDOs or charge pumps in multi-voltage SoC interfaces |
| IOFF partial power-down | Outputs enter high-Z and leakage stays ≤ ±0.75 μA when either VCC = 0 V - safe for hot-plug and sleep-mode isolation |
| Schmitt-trigger inputs | Input hysteresis ≥ 0.4 × VCC across full temperature range - rejects noise on long PCB traces or flex cables |
| Ultra-low ICC | Max 1.4 μA total supply current at +125 °C - extends battery life in always-on sensor nodes and IoT edge devices |
| Small-footprint XSON6 | 1.0 mm × 1.0 mm footprint with 0.35 mm height - ideal for space-constrained wearables and automotive ADAS modules |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |
|---|---|
Use Scenario: Interfacing a 1.8 V microcontroller GPIO to a 3.3 V CAN transceiver's standby control line. IC Role / Device Role / Timing Role: Bidirectional level translator enabling MCU-initiated wake-up and transceiver-reported status feedback over shared signal line. Use Value: Eliminates discrete MOSFET-based level shifter, reducing BOM count and layout area while maintaining <10 ns propagation delay for real-time response. | Use Scenario: Connecting a 1.2 V FPGA configuration interface to legacy 2.5 V digital I/O expansion cards. IC Role / Device Role / Timing Role: Voltage-domain bridge supporting JTAG/SPI configuration and status polling without violating I/O voltage limits. Use Value: Prevents FPGA I/O damage during hot-swap of expansion modules by enforcing IOFF behavior when 2.5 V rail powers down first. |
| Medical Wearable Sensor Hub | Smart Energy Meter Communication Interface |
Use Scenario: Linking a 1.5 V ultra-low-power sensor ASIC to a 3.3 V BLE radio subsystem. IC Role / Device Role / Timing Role: Low-leakage bidirectional data path enabling sensor data streaming and radio command acknowledgment. Use Value: Sub-μA static current preserves battery runtime; Schmitt inputs tolerate noisy analog-rich PCB environments near ECG electrodes. | Use Scenario: Isolating a 1.8 V metrology SoC from a 3.3 V RS-485 transceiver in a DIN-rail mounted meter. IC Role / Device Role / Timing Role: Level-translating control/data bus between metrology core and isolated comms layer. Use Value: IOFF protection ensures no backfeed into SoC during RS-485 transceiver power cycling - critical for firmware update reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | 2-channel, auto-direction sensing, higher ICC (10 μA typ), larger X2SON8 package | Requires no DIR signal; unsuitable for deterministic direction control in synchronous protocols | Select when DIR pin routing is constrained and direction is data-driven rather than control-driven |
| SN74LVC1T45DBVR | Single-channel, same pinout, wider VCC range (1.65 V–5.5 V), higher drive strength (32 mA), no IOFF | Lacks power-down isolation - unsafe for asymmetric power sequencing | Select only in fixed-rail 3.3 V/5 V systems where both supplies remain active during sleep |
Compared with TXS0102DCUR and SN74LVC1T45DBVR, the 74AUP1T45GS,132 uniquely balances ultra-low ICC (<1.4 μA), guaranteed IOFF protection, and minimal 1.0 mm² footprint - making it optimal for battery-powered, multi-rail, and automotive-grade designs requiring fail-safe power sequencing.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet permits any combination within 1.1 V to 3.6 V per rail - including ΔVCC up to 2.5 V (e.g., VCC(A) = 1.1 V, VCC(B) = 3.6 V). No derating is required, and all DC and dynamic specs remain valid across this full differential range.
Does the 74AUP1T45GS,132 support hot-swapping between powered and unpowered domains?
Yes - its IOFF circuit guarantees that when either VCC(A) or VCC(B) is at 0 V, both A and B terminals enter high-impedance state with leakage ≤ ±0.75 μA. This prevents damaging current flow during live insertion or asymmetric power sequencing.
Can the DIR input be driven from a different voltage domain than VCC(A)?
No - DIR is strictly referenced to VCC(A), and its VIH/VIL thresholds scale with VCC(A) (e.g., VIH = 0.7 × VCC(A)). Driving DIR from VCC(B) violates absolute maximum ratings and may cause undefined logic states or increased leakage.
Is the XSON6 (SOT1202) package RoHS and REACH compliant?
Yes - the 74AUP1T45GS,132 in SOT1202 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound, certified per Nexperia's official compliance documentation.
