Product details
Overview
74AVC1T45GN,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 isolated VCC(A) and VCC(B) supplies, DIR-controlled direction, IOFF partial power-down protection, and operates across –40 °C to +125 °C for mixed-voltage SoC interfacing in portable and industrial systems.
For engineers reviewing the 74AVC1T45GN,132 datasheet, 74AVC1T45GN,132 pinout, 74AVC1T45GN,132 application, or 74AVC1T45GN,132 equivalent, key selection criteria include dual-rail supply flexibility, sub-10 ns propagation delay at 1.8 V/3.3 V, IOFF-enabled suspend mode, ESD robustness (8 kV HBM), and XSON6 (SOT1115) package compatibility with high-density PCB layouts.
Technical Context
The device implements a bidirectional, direction-controlled transceiver architecture where DIR referenced to VCC(A) selects data flow: HIGH enables A→B, LOW enables B→A. Both I/O ports are referenced to their respective supplies, eliminating level-shifter bias networks.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) = GND, preventing backflow current and ensuring high-impedance OFF-state during partial power-down-critical for battery-backed subsystems and hot-plug interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) / VCC(B) Range | 0.8 V to 3.6 V each - supports translation between any two low-voltage nodes (e.g., 1.2 V ↔ 1.8 V, 1.8 V ↔ 3.3 V) without external components |
| Propagation Delay (A→B) | ≤ 7.1 ns at VCC(A)=3.3 V, VCC(B)=3.3 V, –40 °C to +85 °C - enables >140 MHz data rates in synchronous interfaces |
| IOFF Leakage Current | ±1 μA max per port at VCC = 0 V - ensures <1 μA bus leakage during suspend, preserving battery life in always-on subsystems |
| ESD Protection | HBM ≥ 8000 V, CDM ≥ 1000 V - meets IEC 61000-4-2 Level 4 for robust handling in manufacturing and field deployment |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial control, and telecom infrastructure applications |
| Dynamic Power Dissipation | CPD = 2 pF (A→B) / 17 pF (B→A) at 3.3 V - enables ultra-low dynamic power in high-speed, low-duty-cycle signal routing |
Pinout & Package
XSON6 package (SOT1115): extremely thin small outline, no leads, 6-terminal, body size 0.9 × 1.0 × 0.35 mm, thermal pad optional, pin 1 index at lower-left corner below marking code "B5".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC(A) | Supply rail for port A and DIR input | References A and DIR logic thresholds; must be stable before signal assertion to avoid metastability |
| 2 - GND | Digital ground reference | Common return for both supply domains; requires low-inductance connection to minimize noise coupling |
| 3 - A | Bidirectional data I/O port A | Signal referenced to VCC(A); functions as input or output depending on DIR state and VCC(B) activity |
| 4 - B | Bidirectional data I/O port B | Signal referenced to VCC(B); electrically isolated from A domain except through active transceiver path |
| 5 - DIR | Direction control input | Active-HIGH A→B, active-LOW B→A; sampled synchronously with VCC(A); no internal pull-up/down |
| 6 - VCC(B) | Supply rail for port B | References B logic thresholds and output drive strength; independent of VCC(A) for true dual-rail operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) independently configurable from 0.8 V to 3.6 V - eliminates need for external level-shifting resistors or charge pumps |
| IOFF partial power-down | Outputs enter high-Z when either VCC = GND - prevents back-current damage and enables safe hot-swap of voltage domains |
| Sub-10 ns propagation delay | tpd ≤ 7.1 ns (A→B) at 3.3 V/3.3 V - supports USB 2.0, SDIO, and MIPI I3C auxiliary channel timing budgets |
| Overvoltage-tolerant inputs | Inputs withstand up to 3.6 V regardless of VCC - allows interfacing with legacy 3.3 V peripherals while operating at 1.2 V core |
| Low dynamic power | CPD = 2 pF (A→B) at 3.3 V - reduces switching power by >5× vs. older AVC families, critical for battery-powered edge sensors |
Applications
| Mobile SoC Interfacing | Automotive ADAS Sensor Hub |

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-channel, 1.2 V–3.6 V, auto-direction sensing (no DIR pin), higher CPD (12 pF), 125 °C rated | Eliminates DIR control but adds bus contention risk in bidirectional use; less suitable for deterministic direction switching | Select when system lacks dedicated DIR line and bus arbitration is handled externally |
| SN74AVC1T45DBVR | Same function, SOT-23-6 package (larger footprint, 2.9 × 1.6 mm), higher thermal resistance (270 K/W), identical specs | Compatible for prototyping or legacy board reuse but unsuitable for space-constrained wearables or modules | Select when XSON6 assembly capability is unavailable or rework tolerance is prioritized over miniaturization |
Compared with TXS0101DCUR, 74AVC1T45GN,132 offers precise DIR-controlled directionality and lower dynamic capacitance for timing-critical links; versus SN74AVC1T45DBVR, it delivers 65 % smaller footprint and 40 % lower θJA for thermally constrained edge devices.

FAQ
What is the minimum valid voltage difference between VCC(A) and VCC(B)?
No minimum voltage difference is required: VCC(A) and VCC(B) may be equal (e.g., both 1.8 V) or differ by as little as 0.1 V (e.g., 1.2 V and 1.3 V) while maintaining full functionality, timing, and drive strength per datasheet specifications.
Can DIR be driven from a different voltage domain than VCC(A)?
No - DIR is strictly referenced to VCC(A); applying a voltage outside the 0 V to VCC(A) range violates absolute maximum ratings and may cause latch-up or permanent damage. A level shifter is required if DIR originates from another supply domain.
Does the device support hot insertion when one supply is powered and the other is off?
Yes - IOFF circuitry ensures both A and B ports enter high-impedance OFF-state when either VCC(A) or VCC(B) = GND, preventing back-current and enabling safe hot insertion into live backplanes or modular systems.
How does propagation delay vary with asymmetric supply combinations?
Delay is asymmetric: A→B delay depends primarily on VCC(A) and VCC(B) values, while B→A delay depends on VCC(B) and VCC(A); Table 12 provides min/max values across all 1.2 V–3.3 V combinations at –40 °C to +125 °C for accurate timing closure.
