Product details
Overview
74AVC2T45GS-Q100 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 two data ports (1A/2A referenced to VCC(A), 1B/2B to VCC(B)), DIR-controlled direction, IOFF partial power-down, and AEC-Q100 Grade 1 qualification for automotive use in ADAS sensor interfaces and infotainment domain controllers.
For engineers reviewing the 74AVC2T45GS-Q100 datasheet, 74AVC2T45GS-Q100 pinout, 74AVC2T45GS-Q100 application, or 74AVC2T45GS-Q100 equivalent, key selection criteria include bidirectional translation capability across mismatched supply rails, Suspend mode behavior during partial power-down, propagation delay vs. voltage pairing (e.g., 11.8 ns A→B at 3.3 V→3.3 V), and XSON8 (SOT1203) package thermal and routing constraints.
Technical Context
This device implements a dual-rail transceiver architecture with independent VCC(A) and VCC(B) supplies, each supporting 0.8 V–3.6 V. Direction control is asserted via DIR (referenced to VCC(A)), enabling A→B transmission on HIGH and B→A on LOW. The IOFF circuit disables outputs when either supply is at GND, preventing backflow current.
Suspend mode activates when VCC(A) = GND or VCC(B) = GND, forcing both ports into high-impedance OFF-state. Input thresholds scale with respective supply voltages (e.g., VIH = 0.65×VCC(A) for 1.1–1.95 V), and output drive strength is specified per load condition (e.g., VOL = 0.7 V @ IO = 12 mA, VCC = 3.0 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 0.8 V–3.6 V; VCC(B): 0.8 V–3.6 V - enables translation between any low-voltage node (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V) |
| Max Data Rate | 500 Mbit/s - achievable only for 1.8 V–3.3 V translation; drops to 240 Mbit/s for 1.2 V translation due to timing margins |
| Propagation Delay | A→B: 11.8 ns @ VCC(A)=VCC(B)=3.3 V - defines minimum clock period for synchronous bus bridging |
| IOFF Leakage | ±35 μA @ -40 °C to +125 °C - ensures safe isolation during partial power-down without external pull resistors |
| ESD Protection | HBM >8 kV, CDM >1 kV - meets automotive robustness requirements for in-vehicle PCB handling and operation |
| Operating Temp | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cockpit electronics |
| Input Thresholds | VIH = 0.65×VCC(A), VIL = 0.35×VCC(A) - rail-proportional logic thresholds prevent misreads during voltage ramp-up |
Pinout & Package
XSON8 package (SOT1203): extremely thin small outline, no leads, 1.35 mm × 1.0 mm × 0.35 mm body, 8 terminals, wettable flank compatible for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for port A (1A, 2A, DIR); sets input thresholds and output drive levels for A-side signals |
| 2 | 1B | Data I/O terminal referenced to VCC(B); bidirectionally translates with 1A based on DIR state |
| 3 | 2B | Data I/O terminal referenced to VCC(B); bidirectionally translates with 2A based on DIR state |
| 4 | GND | Common reference for all internal circuitry; must be low-impedance to minimize ground bounce during switching |
| 5 | DIR | Direction control input referenced to VCC(A); HIGH enables 1A↔1B and 2A↔2B translation A→B |
| 6 | 2A | Data I/O terminal referenced to VCC(A); bidirectionally translates with 2B based on DIR state |
| 7 | 1A | Data I/O terminal referenced to VCC(A); bidirectionally translates with 1B based on DIR state |
| 8 | VCC(B) | Supply for port B (1B, 2B); sets input thresholds and output drive levels for B-side signals |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Translation | Single DIR pin controls full-duplex data flow between independent voltage domains without external OE logic |
| IOFF Partial Power-down | Automatically disables outputs when either VCC(A) or VCC(B) = GND, eliminating need for external isolation switches |
| Suspend Mode | Both A and B ports enter high-Z simultaneously if either supply collapses - prevents bus contention in multi-rail systems |
| Rail-Proportional Thresholds | VIH/VIL track VCC(A) and VCC(B) - ensures reliable sampling across wide voltage combinations (e.g., 1.2 V MCU ↔ 3.3 V sensor) |
| AEC-Q100 Grade 1 | Qualified for automotive applications requiring operation from -40 °C to +125 °C ambient, including engine control units |

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 |
|---|---|---|---|
| SN74AVC2T45RSWR | Same functional spec but non-automotive grade; max temp +85 °C; no AEC-Q100 qualification | Not suitable for under-hood or safety-critical modules requiring Grade 1 reliability | Select only for cost-sensitive consumer or industrial designs outside automotive temperature range |
| TXS0102DCUR | Auto-direction sensing (no DIR pin); higher ICC (25 μA typical); lower max speed (24 Mbps) | Lacks deterministic direction control - unsuitable for protocols requiring strict bus arbitration like SPI or I²C with clock stretching | Prefer where automatic direction detection simplifies firmware and speed <100 Mbps suffices |
Compared with SN74AVC2T45RSWR and TXS0102DCUR, the 74AVC2T45GS-Q100 uniquely delivers AEC-Q100 Grade 1 compliance, 500 Mbit/s performance, and explicit DIR control - making it the only choice for high-speed, safety-aware automotive domain bridging.

FAQ
What is the minimum valid VCC(A)/VCC(B) combination for reliable operation?
The device operates reliably with any VCC(A) and VCC(B) pair between 0.8 V and 3.6 V inclusive. Valid combinations include asymmetric rails such as VCC(A) = 1.2 V / VCC(B) = 3.3 V or VCC(A) = 0.8 V / VCC(B) = 1.8 V. Operation below 0.8 V violates recommended conditions and may cause undefined logic states or excessive propagation delay.
How does Suspend mode behave when only VCC(A) is powered down?
When VCC(A) = GND and VCC(B) remains active, both A-port (1A, 2A) and B-port (1B, 2B) terminals enter high-impedance OFF-state regardless of DIR or input states. This prevents back-driving of the powered B-side bus and eliminates contention - a critical feature for hot-swap or phased power-down architectures.
Can the 74AVC2T45GS-Q100 translate between 5 V and 3.3 V logic domains?
No. Absolute maximum input voltage is 3.6 V, and inputs are not 5 V tolerant. Applying 5 V to any pin (including 1A, 2A, 1B, 2B, or DIR) exceeds limiting values and risks permanent damage. For 5 V ↔ 3.3 V translation, a dedicated 5 V-tolerant translator such as 74LVC2T45 must be used instead.
Is the XSON8 (SOT1203) package compatible with standard reflow profiles?
Yes. The SOT1203 package supports IPC/JEDEC J-STD-020D-compliant lead-free reflow profiles, including peak temperatures up to 260 °C for 30 seconds. Its 0.35 mm height and wettable flanks enable reliable solder joint inspection using automated optical inspection (AOI) systems common in automotive PCB assembly lines.
