Product details
Overview
74AVC1T45GS,132 from Nexperia is a single-bit dual-supply voltage level translator/transceiver with 3-state output, enabling bidirectional logic-level translation between independent 0.8 V–3.6 V domains (e.g., 1.2 V ↔ 3.3 V). It features separate VCC(A) and VCC(B) supplies, DIR-controlled directionality, IOFF circuitry for partial power-down, and operates across –40 °C to +125 °C.
For engineers reviewing the 74AVC1T45GS,132 datasheet, 74AVC1T45GS,132 pinout, 74AVC1T45GS,132 application, or 74AVC1T45GS,132 equivalent, key selection criteria include dual-rail voltage flexibility, sub-10 ns propagation delay at 1.8 V/3.3 V, IOFF-enabled suspend mode, ±5 μA max OFF-state leakage, and XSON6 (SOT1202) 1.0 × 1.0 × 0.35 mm package compatibility with high-density PCB layouts.
Technical Context
The device implements a bidirectional data path controlled by a single DIR input referenced to VCC(A); HIGH enables A→B translation, LOW enables B→A. Both I/O ports are fully rail-to-rail compatible and tolerate inputs up to 3.6 V regardless of supply voltage.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) = 0 V, forcing A and B into high-impedance OFF-state and blocking damaging backflow current-critical for hot-swap and multi-rail system power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 0.8 V to 3.6 V - supports interface between ultra-low-voltage cores (e.g., 0.8 V FPGA I/O) and higher-voltage peripherals |
| VCC(B) Range | 0.8 V to 3.6 V - independent biasing enables asymmetric translation (e.g., 1.2 V MCU ↔ 2.5 V sensor) |
| tpd (A→B, 1.8 V→3.3 V) | 7.7 ns - ensures timing closure in high-speed interconnects like SDIO, I²C fast-mode+, or GPIO expansion |
| IOFF Leakage (VCC = 0 V) | ±5 μA max - guarantees safe isolation during power-down without external pull resistors or sequencing control |
| ESD Rating (HBM) | >8000 V - meets industrial-grade robustness requirements for exposed board-level interfaces |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and telecom infrastructure use |
| Package | XSON6 (SOT1202), 1.0 × 1.0 × 0.35 mm - 0.4 mm pitch, no leads, optimized for automated assembly and thermal performance |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT1202); 6 terminals; body dimensions 1.0 mm × 1.0 mm × 0.35 mm; leadless, bottom-terminal layout; moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply reference for port A and DIR input - defines logic thresholds for A and DIR signals |
| 2 | GND | Common ground return - mandatory first connection during power-up per JEDEC guidelines |
| 3 | A | Bidirectional data terminal referenced to VCC(A) - functions as input or output depending on DIR state |
| 4 | B | Bidirectional data terminal referenced to VCC(B) - electrically isolated from A domain except during active translation |
| 5 | DIR | Direction control input (VCC(A)-referenced) - LOW = B→A, HIGH = A→B; no internal pull-up/down |
| 6 | VCC(B) | Supply reference for port B - sets output swing and input threshold for B-side signals |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | Enables seamless translation between mismatched voltage domains without level-shifter ICs or discrete resistor networks |
| IOFF partial power-down | Prevents back-current flow when one supply is off - eliminates need for external isolation switches in battery-backed subsystems |
| Sub-10 ns propagation delay | Supports >100 MHz data rates in unidirectional mode (e.g., 500 Mbit/s A→B at 1.8 V→3.3 V), meeting USB 2.0 and MIPI I3C timing budgets |
| Overvoltage-tolerant inputs | Accepts up to 3.6 V on A/B pins regardless of VCC(A)/VCC(B) - simplifies interface to legacy 3.3 V peripherals in low-voltage SoC designs |
| Low dynamic power dissipation | CPD = 2 pF (A→B) / 17 pF (B→A) at 3.3 V - reduces switching noise and heat in compact, fanless embedded systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCUR | Single-bit, 1.2 V–3.6 V, auto-direction sensing (no DIR pin), higher ICC (20 μA vs. 16 μA) | Eliminates DIR control logic but adds bus contention risk in bidirectional mode without careful protocol design | Preferred when direction is predictable and deterministic (e.g., I²C SDA/SCL), not for arbitrary GPIO translation |
| SN74LVC1T45DBVR | Same pinout/function, but only rated to +85 °C; lower ESD (4000 V HBM); no IOFF circuitry | Lacks suspend-mode isolation - unsuitable for systems requiring partial power-down or hot-swap capability | Select only for commercial-temperature consumer applications where cost is primary and IOFF is unnecessary |
Compared with TXS0101DCUR and SN74LVC1T45DBVR, the 74AVC1T45GS,132 uniquely combines industrial temperature range, IOFF-enabled power-down safety, and explicit DIR control - making it optimal for automotive, industrial, and high-reliability embedded designs demanding deterministic behavior and robust fault tolerance.

FAQ
What is the minimum recommended supply voltage for reliable operation?
The 74AVC1T45GS,132 is fully specified from 0.8 V to 3.6 V on both VCC(A) and VCC(B). At 0.8 V, VIH is 0.70 × VCC(A) = 0.56 V and VOL is 0.07 V (typical), ensuring noise margins >150 mV. Operation below 0.8 V is not characterized and may result in undefined logic states or increased propagation delay.
Can VCC(A) and VCC(B) be powered from different sources with independent sequencing?
Yes - the device supports independent power sequencing. GND must be applied first, but VCC(A) and VCC(B) may be ramped independently. When either supply is at 0 V, IOFF forces both A and B into high-impedance, preventing back-current. No external power-good sequencing circuitry is required.
Is a pull-up or pull-down resistor required on the DIR pin?
No - DIR has no internal termination. In systems where DIR state is not actively driven during reset or power-up, an external pull-up (to VCC(A)) or pull-down (to GND) is required to ensure deterministic direction at startup and avoid floating inputs that could cause bus contention.
How does the device behave during power-down of only one supply rail?
When VCC(A) = 0 V and VCC(B) = 3.3 V, IOFF activates: A port leakage is ±5 μA max, B port remains functional but A is isolated. Similarly, if VCC(B) = 0 V, B is isolated while A retains full functionality. This enables true partial power-down in multi-rail SoC subsystems.
