Product details
Overview
74AVC4T774GU-Q100 from Nexperia is a 4-bit dual-supply translating transceiver enabling bidirectional level translation between independent voltage domains (VCC(A) and VCC(B), each 0.8 V to 3.6 V). It features eight I/O ports (A1–A4, B1–B4), four direction controls (DIR1–DIR4), active-low output enable (OE), and IOFF partial power-down protection. Used in automotive infotainment domain controllers for interfacing 1.2 V sensor interfaces with 3.3 V MCU buses.
For engineers reviewing the 74AVC4T774GU-Q100 datasheet, 74AVC4T774GU-Q100 pinout, 74AVC4T774GU-Q100 application, or 74AVC4T774GU-Q100 equivalent, key selection criteria include bidirectional translation capability across mismatched supply rails, AEC-Q100 Grade 1 qualification, suspend-mode isolation, and 380 Mbit/s max data rate at ≥1.8 V/3.3 V translation.
Technical Context
This device implements four independent 1-bit bidirectional transceivers, each with dedicated DIRn control and shared OE. Signal flow direction per channel is determined solely by DIRn logic level relative to VCC(A), while all An pins reference VCC(A) and all Bn pins reference VCC(B).
The IOFF circuit enforces high-impedance OFF-state on both A and B ports when either VCC(A) or VCC(B) is at GND, preventing backflow current during partial power-down. Suspend mode behavior is guaranteed across the full -40 °C to +125 °C automotive temperature range.
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 among 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| Max Data Rate | 380 Mbit/s - supports high-speed interconnects such as camera sensor links or display interface bridges |
| Propagation Delay | Min 0.2 ns (An→Bn @ 3.3 V/3.3 V); Max 15.6 ns (OE→Bn @ -40 °C to +125 °C) - ensures timing predictability in real-time automotive subsystems |
| IOFF Leakage | ±1 μA max (VCC = 0 V) - guarantees safe hot-plug operation and prevents bus contention during power sequencing |

Pinout & Package
XQFN16 package (SOT1161-1): plastic, extremely thin quad flat, no leads, 16 terminals, body size 1.80 × 2.60 × 0.50 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4 (A1–A4) | Data I/O port A | Referenced to VCC(A); bidirectional under DIRn and OE control |
| 5–6 (DIR3, DIR4) | Direction control input | Active HIGH enables A→B flow; LOW enables B→A flow per channel |
| 7 (OE) | Output enable (active LOW) | Drives all A/B outputs to high-impedance when HIGH |
| 8 (GND) | Ground reference | 0 V reference for internal logic and ESD structures |
| 9–12 (B4–B1) | Data I/O port B | Referenced to VCC(B); isolated from A-side supply and noise |
| 13 (VCC(B)) | Supply voltage B | Power rail for B-side I/O buffers and level-shifting circuitry |
| 14 (VCC(A)) | Supply voltage A | Power rail for A-side I/O buffers, DIRn, and OE inputs |
| 15–16 (DIR1, DIR2) | Direction control input | Same function as DIR3/DIR4; fully independent per channel |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional level translation | Four independent channels support simultaneous A↔B translation across mismatched supplies (e.g., 1.2 V ↔ 3.3 V) |
| IOFF partial power-down | Prevents damaging backflow current when either VCC(A) or VCC(B) is unpowered - critical for modular automotive ECUs |
| Suspend mode | Both A and B ports enter high-Z state automatically if either supply drops to GND - eliminates need for external isolation logic |
| AEC-Q100 Grade 1 | Qualified for automotive use from -40 °C to +125 °C ambient - validated for lifetime reliability in safety-critical systems |
| Low dynamic power | CPD as low as 0.2 pF per A-port path - reduces switching power in high-frequency data paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC4T245QPWRQ1 | TI part uses single OE for all channels; lacks per-channel DIR control; CPD up to 13.5 pF (vs. 0.2–11.9 pF) | Less flexible for mixed-direction protocols; higher dynamic power limits max frequency in dense routing | Preferred only when consolidated OE simplifies control logic and lower speed (<100 Mbit/s) suffices |
| TXS0104EPWR | TI auto-sensing direction; no DIR pins; supports 1.65–3.6 V only; no AEC-Q100 Grade 1 rating | Not qualified for under-hood or safety-critical use; unsuitable where deterministic direction control is required | Select only for non-automotive industrial applications requiring zero-control-pin operation |
Compared with SN74AVC4T245QPWRQ1 and TXS0104EPWR, the 74AVC4T774GU-Q100 provides per-channel direction control, lowest CPD for highest-speed operation, and full AEC-Q100 Grade 1 qualification - making it the sole choice for timing-critical, safety-relevant automotive domain bridging.

FAQ
What is the minimum valid supply voltage for simultaneous operation of both VCC(A) and VCC(B)?
The device operates correctly with both supplies as low as 0.8 V, provided they remain within the 0.8 V–3.6 V range and meet recommended operating conditions. Static and dynamic parameters-including VIH/VIL thresholds and propagation delay-are fully specified down to 0.8 V, enabling ultra-low-voltage subsystem interfacing in modern automotive SoCs.
How does the IOFF feature behave when only VCC(A) is powered?
When VCC(A) is powered and VCC(B) = 0 V, the IOFF circuit forces all B-side outputs into high-impedance, while A-side I/O remains functional but cannot drive B-side loads. Input leakage on B pins is limited to ±1 μA, preventing unintended current paths - a key requirement for modular ECU power architecture.
Can DIRn pins be tied together for synchronous direction control across all four channels?
Yes - DIR1 through DIR4 may be externally wired together without electrical conflict, enabling unified A→B or B→A translation for protocols like parallel data buses. This configuration maintains full timing specifications and does not affect IOFF or suspend functionality.
Is the XQFN16 (SOT1161-1) package compatible with standard reflow profiles for lead-free assembly?
Yes - the XQFN16 package is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature tolerance up to 260 °C. Its 0.50 mm profile and thermal pad design support efficient heat dissipation during automated assembly, meeting IPC-A-610 Class 3 requirements for automotive production.
