Product details
Overview
74AVC2T45GT,115 from Nexperia is a dual-bit, dual-supply voltage level translator/transceiver enabling bidirectional logic-level translation between 0.8 V and 3.6 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled data direction (A↔B), and IOFF circuitry for partial power-down protection. Used in mixed-voltage SoC interconnects, such as translating between 1.8 V FPGA I/O and 3.3 V peripheral buses.
For engineers reviewing the 74AVC2T45GT,115 datasheet, 74AVC2T45GT,115 pinout, 74AVC2T45GT,115 application, or 74AVC2T45GT,115 equivalent, key selection criteria include bidirectional translation capability, IOFF-enabled suspend mode, 8-pin XSON package footprint, -40 °C to +125 °C operation, and JEDEC-compliant voltage thresholds across multiple supply combinations.
Technical Context
The device implements a dual-rail transceiver architecture with separate input/output referencing: pins 1A, 2A, and DIR are referenced to VCC(A); pins 1B and 2B to VCC(B). Direction control is asynchronous and single-input (DIR), determining real-time signal flow without clocking or handshaking.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing both ports into high-impedance OFF-state to prevent backflow current. IOFF circuitry ensures sub-μA leakage (< ±35 μA at 125 °C) during partial power-down, meeting JESD78 Class II latch-up immunity (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply range VCC(A)/VCC(B) | 0.8 V to 3.6 V each - enables translation between any two low-voltage nodes (e.g., 1.2 V ↔ 2.5 V, 1.8 V ↔ 3.3 V) |
| Max data rate | 500 Mbit/s (1.8 V–3.3 V translation) - supports high-speed serial control links and memory interface bridging |
| Propagation delay (A→B) | ≤ 9.2 ns @ VCC(A)=VCC(B)=3.3 V - ensures timing-critical bidirectional bus synchronization |
| IOFF leakage current | ±35 μA max @ -40 °C to +125 °C - guarantees safe hot-swap and power-gating in multi-rail systems |
| ESD protection | HBM > 8000 V, CDM > 1000 V - meets industrial-grade robustness requirements for board-level handling |
| Operating temperature | -40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments |
| Input voltage tolerance | Accepts up to 3.6 V on all inputs regardless of VCC - simplifies interfacing with legacy 3.3 V signals into lower-voltage domains |
Pinout & Package
XSON8 plastic extremely thin small outline package (SOT833-1); 8-terminal, leadless; body dimensions 1.0 mm × 1.95 mm × 0.5 mm; thermal pad optional; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply reference for DIR and A-side I/O (1A, 2A); sets input thresholds and output drive levels for port A |
| 2 | 1B | Data terminal referenced to VCC(B); functions as input or output depending on DIR state |
| 3 | 2B | Data terminal referenced to VCC(B); functions as input or output depending on DIR state |
| 4 | VCC(B) | Supply reference for B-side I/O (1B, 2B); independent of VCC(A), enabling asymmetric voltage translation |
| 5 | DIR | Direction control input (HIGH = A→B, LOW = B→A); referenced to VCC(A), immune to VCC(B) fluctuations |
| 6 | 2A | Data terminal referenced to VCC(A); functions as input or output depending on DIR state |
| 7 | 1A | Data terminal referenced to VCC(A); functions as input or output depending on DIR state |
| 8 | GND | Common ground reference for internal logic and ESD protection network; must be connected for IOFF functionality |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply rail independence | VCC(A) and VCC(B) operate independently across 0.8–3.6 V - eliminates need for external level-shifting components in heterogeneous voltage systems |
| IOFF partial power-down | Disables outputs and blocks backflow current when either supply is at GND - enables safe live insertion and dynamic rail gating |
| JEDEC compliance | Validated per JESD8-12 through JESD8-B across six voltage bands - ensures interoperability with standard low-voltage logic families |
| Low noise switching | Overshoot/undershoot < 10 % of VCC - reduces EMI and signal integrity risk in dense PCB layouts |
| High-speed enable/disable | Enable time ≤ 22.0 ns (DIR→B @ 3.3 V), disable time ≤ 10.2 ns - minimizes bus turnaround latency in bidirectional protocols |

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 |
|---|---|---|---|
| TXS0102DCUR | 2-bit, dual-supply; no IOFF; max VCC = 5.5 V; higher ICC (120 μA typ); 8-pin VSSOP only | Lacks suspend mode - unsuitable for partial power-down systems requiring backflow prevention | Select when higher voltage tolerance (up to 5.5 V) is required and IOFF is not needed. |
| SN74AVC2T245RSWR | 2-bit, dual-supply; includes OE pin; IOFF supported; 10-pin UQFN; wider temp range (-40 °C to +125 °C) | Additional OE control adds complexity but enables explicit tri-state override independent of DIR | Select when system requires hardware-enforced bus isolation beyond DIR-based direction control. |
Compared with TXS0102DCUR and SN74AVC2T245RSWR, the 74AVC2T45GT,115 delivers superior power-down safety via integrated IOFF, smaller XSON8 footprint (1.0 × 1.95 mm), and tighter propagation delay consistency across voltage combinations - critical for timing-sensitive bidirectional interfaces.

FAQ
What is the minimum valid VCC(A) and VCC(B) voltage for functional operation?
The 74AVC2T45GT,115 operates reliably down to 0.8 V on both VCC(A) and VCC(B) rails, with guaranteed VIH/VIL thresholds defined per JESD8 standards across that range. Below 0.8 V, static characteristics (e.g., VOH/VOL) degrade, and propagation delay increases beyond specification limits - operation is not characterized or recommended.
Can DIR be driven from a different voltage domain than VCC(A)?
No. DIR is strictly referenced to VCC(A); its input threshold scales with VCC(A) (VIH = 0.65×VCC(A) min, VIL = 0.35×VCC(A) max). Driving DIR from a non-VCC(A) source risks undefined logic states, increased input leakage, and potential damage if voltage exceeds VCC(A) + 0.5 V absolute maximum rating.
How does the device behave when only VCC(A) is powered and VCC(B) = GND?
In this condition, the device enters Suspend mode: both A and B ports go high-impedance (Z), IOFF circuitry activates, and leakage current is limited to ±35 μA max. No signal transmission occurs, and backflow current from B-side traces into the unpowered VCC(B) rail is blocked - a key safety feature for hot-plug and rail sequencing scenarios.
Is the XSON8 package (SOT833-1) compatible with standard reflow profiles?
Yes. The 74AVC2T45GT,115 in SOT833-1 meets IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1) and is qualified for standard Pb-free reflow profiles with peak temperature ≤ 260 °C. Its 0.5 mm profile and thermal pad option support efficient heat dissipation during assembly and operation.
