Product details
Overview
74AVC20T245DGG-Q1J from Nexperia is a 20-bit dual-supply translating transceiver enabling bidirectional voltage level translation between independent 0.8 V–3.6 V domains. It operates as two 10-bit or one 20-bit transceiver, with separate VCC(A) and VCC(B), four I/O port groups (1An/1Bn/2An/2Bn), two direction controls (1DIR/2DIR), and two active-low output enables (1OE/2OE). Used in automotive infotainment domain controllers interfacing 1.2 V SoCs with 3.3 V sensor hubs.
For engineers reviewing the 74AVC20T245DGG-Q1J datasheet, 74AVC20T245DGG-Q1J pinout, 74AVC20T245DGG-Q1J application, or 74AVC20T245DGG-Q1J equivalent, key selection criteria include bidirectional translation across mismatched supply rails, AEC-Q100 Grade 1 qualification, IOFF-enabled partial power-down, and 380 Mbit/s max data rate at ≥1.8 V → 3.3 V translation.
Technical Context
This device implements dual-rail CMOS logic with independent input referencing: 1An/2An/1DIR/2DIR/1OE/2OE tied to VCC(A), while 1Bn/2Bn referenced to VCC(B). Direction control is asynchronous-HIGH on nDIR enables A→B transmission; LOW enables B→A. Output enable is active-low and overrides direction state.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing all outputs into high-impedance OFF-state regardless of OE/DIR states. The IOFF circuitry actively disables outputs during power-down, limiting backflow current to ±1 μA (max) and meeting JESD78 Class II latch-up immunity (>100 mA).
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 - supports translation between any low-voltage nodes (0.8/1.2/1.5/1.8/2.5/3.3 V) |
| Max Data Rate | 380 Mbit/s - achievable only for ≥1.8 V → 3.3 V translation; drops to 100 Mbit/s for 1.1 V → 1.2 V |
| Propagation Delay | 2.9 ns (min) to 16.9 ns (max) - varies by supply pair and direction; e.g., 2.9 ns for 3.3 V → 3.3 V A→B at +125 °C |
| IOFF Leakage | ±1 μA (max) - ensures safe hot-insertion and partial power-down without damaging backflow current |
| ESD Rating | HBM >8000 V, MM >200 V - exceeds automotive robustness requirements per AEC-Q100 stress test protocols |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and ADAS ECU applications |
Pinout & Package
TSSOP56 plastic thin shrink small outline package (SOT364-1), 56-pin, 6.1 mm body width, 0.5 mm pitch, lead-free and RoHS compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 28 | 1DIR, 2DIR | Asynchronous direction control inputs referenced to VCC(A); HIGH = A→B, LOW = B→A |
| 2–14, 15–27 | 1B1–1B10, 2B1–2B10 | Data I/O ports referenced to VCC(B); bi-directional under DIR control |
| 43–55, 30–42 | 1A1–1A10, 2A1–2A10 | Data I/O ports referenced to VCC(A); bi-directional under DIR control |
| 29, 56 | 2OE, 1OE | Active-low output enable inputs referenced to VCC(A); HIGH forces high-Z outputs |
| 7, 22, 35, 50 | VCC(B), VCC(A) | Independent supply pins - VCC(A) powers A-side logic and controls; VCC(B) powers B-side I/O |
| 4, 11, 18, 25, 32, 39, 46, 53 | GND | Eight dedicated ground connections - all must be connected to system GND for signal integrity and thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including lifetime reliability testing |
| Dual-rail IOFF circuitry | Prevents destructive backflow current when either VCC rail is powered down - critical for domain-isolated ECUs |
| Configurable 10-/20-bit operation | Two independent 10-bit transceivers (1A/1B + 2A/2B) or unified 20-bit path via shared DIR/OE control |
| JEDEC-compliant voltage standards | Meets JESD8-12 through JESD8-B across full 0.8 V–3.6 V range - ensures interoperability with legacy and next-gen logic families |
| Suspend mode on single-rail loss | Automatic high-Z output assertion when either VCC(A) or VCC(B) = GND - eliminates bus contention during power sequencing |
Applications
| ADAS Sensor Fusion Hub | Automotive Infotainment SoC Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC20T245RKL | Same 20-bit dual-supply architecture but rated −40 °C to +85 °C only; no AEC-Q100 qualification | Restricted to non-automotive industrial or consumer systems; lacks extended temperature and stress-test validation | Select only for cost-sensitive non-automotive designs where Grade 1 qualification is unnecessary |
| 74LVC20T245DGG | Single-supply (1.65 V–3.6 V) operation; no independent VCC(A)/VCC(B) - cannot translate across mismatched rails | Limited to same-voltage domain bridging; unsuitable for mixed-voltage automotive subsystems | Use only when both sides operate at identical voltage (e.g., 3.3 V ↔ 3.3 V), not for true level translation |
Compared with SN74AVC20T245RKL and 74LVC20T245DGG, the 74AVC20T245DGG-Q1J uniquely supports AEC-Q100 Grade 1 operation and true bidirectional rail-to-rail translation - essential for automotive domain controllers requiring mixed-voltage interoperability and functional safety compliance.

FAQ
What is the minimum valid supply voltage for reliable operation?
The device is fully specified from 0.8 V to 3.6 V on both VCC(A) and VCC(B) rails. At 0.8 V, static parameters (VIH/VIL, VOH/VOL) and dynamic performance (tpd, data rate) remain guaranteed per datasheet Tables 7 and 12 - no derating required below 1.2 V.
Can 74AVC20T245DGG-Q1J translate between 0.8 V and 3.3 V in both directions simultaneously?
Yes - it supports true bidirectional translation: 0.8 V ↔ 3.3 V is fully supported in both directions. When VCC(A) = 0.8 V and VCC(B) = 3.3 V, A→B translation achieves 120 Mbit/s; B→A achieves 100 Mbit/s, per Table 2's maximum data rates.
How does suspend mode behave if only VCC(A) is powered?
If VCC(A) = 3.3 V and VCC(B) = GND, the B-side I/O ports (1B1–1B10, 2B1–2B10) enter high-impedance OFF-state immediately. A-side ports remain functional but cannot drive B-side loads - all outputs default to Z, preventing bus contention.
Is there internal ESD protection on all I/O pins?
Yes - all I/O pins (1An, 1Bn, 2An, 2Bn) feature integrated ESD protection meeting MIL-STD-883 Class 3B (>8000 V HBM) and JESD22-A115-A (>200 V MM), verified per AEC-Q100 stress test protocol.
