Product details
Overview
74AVC2T45GT-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 independent VCC(A) and VCC(B) supplies, DIR-controlled directionality (A↔B), and IOFF circuitry for partial power-down protection. Used in automotive infotainment and ADAS domain controllers interfacing mixed-voltage peripherals like sensors and microcontrollers.
For engineers reviewing the 74AVC2T45GT-Q100 datasheet, 74AVC2T45GT-Q100 pinout, 74AVC2T45GT-Q100 application, or 74AVC2T45GT-Q100 equivalent, key selection criteria include bidirectional translation capability across wide voltage combinations (e.g., 1.2 V ↔ 3.3 V), AEC-Q100 Grade 1 qualification, Suspend mode behavior during supply loss, and XSON8 package compatibility with high-density PCB layouts.
Technical Context
The device implements a dual-channel, direction-controlled bus transceiver architecture with separate I/O references: pins 1A, 2A, and DIR are referenced to VCC(A); pins 1B and 2B to VCC(B). Direction control is asynchronous and level-sensitive - DIR HIGH enables A→B transmission, DIR LOW enables B→A transmission.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing both ports into high-impedance OFF-state. The IOFF circuit ensures sub-μA leakage (< ±35 μA at +125 °C) during partial power-down, preventing damaging backflow current while maintaining signal integrity on powered rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 0.8 V to 3.6 V; VCC(B): 0.8 V to 3.6 V - supports translation between any low-voltage nodes (0.8/1.2/1.5/1.8/2.5/3.3 V) |
| Max Data Rate | 500 Mbit/s (1.8 V → 3.3 V) - enables high-speed interface bridging for USB, I²C, and SPI peripherals |
| Propagation Delay | 1.0–9.9 ns (A↔B), 1.0–7.9 ns (DIR→port) - ensures timing-critical bidirectional communication in real-time automotive subsystems |
| IOFF Leakage | ±35 μA max at +125 °C - guarantees safe partial power-down without bus contention or latch-up risk |
| ESD Protection | HBM >8 kV, CDM >1 kV - meets stringent automotive ESD immunity requirements per ISO 10605 |
| Operating Temp | −40 °C to +125 °C - qualified for engine bay and ADAS ECU environments |
| AEC-Q100 Grade | Grade 1 - certified for automotive safety-critical applications per AEC standard |
Pinout & Package
XSON8 plastic extremely thin small outline package (SOT833-1); 8-terminal, no-leads; body dimensions 1.0 × 1.95 × 0.5 mm; wettable flank design for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side I/O and DIR input - defines logic thresholds for 1A, 2A, and DIR |
| 2 | 1B | B-side data I/O terminal - referenced to VCC(B); bidirectionally driven based on DIR state |
| 3 | 2B | B-side data I/O terminal - referenced to VCC(B); complements 1B for dual-bit translation |
| 4 | VCC(B) | Supply for B-side I/O - defines logic thresholds for 1B and 2B; independent of VCC(A) |
| 5 | DIR | Direction control input - HIGH enables 1A/2A → 1B/2B; LOW enables reverse flow |
| 6 | 2A | A-side data I/O terminal - referenced to VCC(A); active only when DIR matches direction |
| 7 | 1A | A-side data I/O terminal - referenced to VCC(A); primary channel for A-domain signals |
| 8 | GND | Common ground reference - required for all internal biasing and ESD protection paths |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply bidirectional translation | Enables seamless interconnection of heterogeneous voltage domains (e.g., 1.2 V FPGA core ↔ 3.3 V CAN transceiver) without external level-shifting components |
| IOFF partial power-down | Prevents backflow current when either VCC rail is unpowered - critical for hot-swap and sleep-mode operation in vehicle networks |
| Suspend mode | Automatic high-Z state on both ports if VCC(A) = GND or VCC(B) = GND - eliminates bus contention during power sequencing faults |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including extended life testing and stress screening per AEC standard |
| Low dynamic power dissipation | CPD as low as 1 pF (A-port, 0.8 V) - reduces switching noise and system-level EMI in sensitive RF-adjacent modules |

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; rated −40 °C to +85 °C only; no AEC-Q100 qualification | Not suitable for under-hood or safety-critical modules requiring Grade 1 temp range and stress validation | Select only for cost-sensitive consumer or industrial applications outside automotive qualification scope |
| TXS0102DCUR | Auto-direction sensing (no DIR pin); higher typical propagation delay (14 ns vs. 1.0–9.9 ns); lower max data rate (24 Mbps vs. 500 Mbps) | Unsuitable for high-speed bidirectional protocols (e.g., SPI, MIPI) requiring precise DIR control and sub-10 ns timing | Prefer where automatic direction detection simplifies firmware and speed requirements are ≤24 Mbps |
Compared with SN74AVC2T45RSWR and TXS0102DCUR, the 74AVC2T45GT-Q100 uniquely delivers AEC-Q100 Grade 1 compliance, 500 Mbit/s throughput, and sub-10 ns propagation delay in an XSON8 footprint - making it the only option for high-reliability, high-speed automotive domain bridging.

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 up to 2.8 V (e.g., 0.8 V ↔ 3.6 V). The device operates correctly across the full 0.8 V–3.6 V range on each supply independently, as confirmed in Tables 6 and 9–13 of the datasheet.
How does Suspend mode behave when only VCC(A) is powered?
When VCC(A) = 3.3 V and VCC(B) = GND, both A and B ports enter high-impedance OFF-state per Table 4. This prevents back-driving of the unpowered B-side bus and eliminates contention - a key requirement for modular power domain architectures in modern ECUs.
Can DIR be driven from a 3.3 V microcontroller while VCC(A) = 1.2 V?
No. DIR is referenced to VCC(A), so its VIH/VIL thresholds scale with VCC(A). Driving DIR from 3.3 V while VCC(A) = 1.2 V violates absolute maximum rating VI ≤ VCC(A) + 0.5 V (Table 5), risking damage. DIR must be driven from a source referenced to VCC(A).
Is the XSON8 package (SOT833-1) compatible with standard reflow profiles?
Yes. The SOT833-1 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. Its 0.5 mm profile and wettable flanks support automated optical inspection and high-yield assembly in automotive-grade SMT lines.
