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, AEC-Q100 Grade 1 qualification, 16-pin XQFN package (1.80 × 2.60 × 0.50 mm), suspend-mode isolation, and maximum data rates up to 380 Mbit/s.
Technical Context
This transceiver implements independent per-bit direction control with separate VCC(A) and VCC(B) supplies, allowing asymmetric voltage translation (e.g., 1.2 V ↔ 2.5 V). Each of the four 1-bit channels operates independently: DIRn selects An→Bn (HIGH) or Bn→An (LOW), while OE disables all outputs into high-impedance state.
The IOFF circuit ensures leakage current remains ≤ ±1 μA when either supply is at GND, enabling safe partial power-down in automotive suspend modes. Input thresholds scale with respective VCC (e.g., VIH = 0.65×VCC(A)), and ESD protection meets HBM >8 kV and CDM >1.5 kV per JEDEC JS-001/JS-002.
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 - enables translation across 0.8/1.2/1.5/1.8/2.5/3.3 V logic nodes |
| Max data rate | 380 Mbit/s (≥1.8 V ↔ 3.3 V) - supports high-speed serial interconnects in ADAS sensor hubs |
| Propagation delay | Min 0.2 ns, max 15.6 ns (−40 °C to +125 °C) - ensures timing compliance in real-time automotive control loops |
| IOFF leakage | ≤ ±1 μA at VCC = 0 V - prevents backflow current during domain power sequencing |
| ESD rating | HBM >8000 V, CDM >1500 V - meets stringent automotive board-level robustness requirements |
| Operating temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin applications |
| Power dissipation | 250 mW max (XQFN16 package) - enables compact placement in space-constrained ECUs |
Pinout & Package
XQFN16 plastic extremely thin quad flat package (SOT1161-1); body dimensions 1.80 × 2.60 × 0.50 mm; no leads; thermal pad exposed on underside (non-soldered or floating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4 (A1–A4) | Data I/O port A | Referenced to VCC(A); bidirectional data path for side A logic domain |
| 5–6, 15–16 (DIR3, DIR4, DIR1, DIR2) | Direction control inputs | Per-channel control: HIGH = A→B, LOW = B→A; referenced to VCC(A) |
| 7 (OE) | Output enable (active LOW) | Global 3-state control; disables all A/B outputs simultaneously |
| 8 (GND) | Ground reference | 0 V reference for internal circuitry and signal integrity |
| 9–12 (B4–B1) | Data I/O port B | Referenced to VCC(B); bidirectional data path for side B logic domain |
| 13 (VCC(B)) | Supply B | Power for B-side I/O buffers and level-shifting circuitry |
| 14 (VCC(A)) | Supply A | Power for A-side I/O buffers, DIRn, and OE inputs |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional per-bit translation | Four independent DIRn inputs allow mixed-direction data flow across voltage domains without external logic |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation in safety-critical automotive systems including powertrain and ADAS |
| IOFF partial power-down | Prevents damaging back-current when either VCC(A) or VCC(B) is powered off - essential for domain-based power gating |
| Suspend mode isolation | Both A and B ports enter high-impedance OFF-state when either supply is at GND - guarantees bus decoupling during sleep |
| JEDEC-compliant voltage standards | Meets JESD8-12 through JESD8-B across 0.8 V–3.6 V - ensures interoperability with legacy and next-gen logic families |

FAQ
What is the minimum recommended supply voltage for reliable operation?
The 74AVC4T774GU-Q100 is fully specified from 0.8 V to 3.6 V on both VCC(A) and VCC(B). At 0.8 V, typical propagation delay is 14.5 ns and IOFF leakage remains ≤±1 μA. Operation below 0.8 V is not characterized and may result in undefined logic states or increased static current.
Can VCC(A) and VCC(B) be powered from different voltage rails simultaneously?
Yes - the device is explicitly designed for simultaneous dual-supply operation. Pins A1–A4, DIR1–DIR4, and OE are referenced to VCC(A); B1–B4 are referenced to VCC(B). Independent rail sequencing is supported, including cases where one supply ramps before the other.
Does the XQFN16 package require thermal pad soldering?
No - the thermal pad is electrically isolated and has no electrical requirement for soldering. If soldered, it must remain floating or be connected to GND; improper connection risks signal integrity degradation or latch-up due to parasitic coupling.
How does suspend mode behave when only VCC(A) is at GND?
When VCC(A) = GND and VCC(B) = 3.6 V, the A-side I/Os (A1–A4) and control inputs (DIR1–DIR4, OE) enter high-impedance OFF-state. B-side I/Os (B1–B4) also go to high-impedance regardless of VCC(B) status - ensuring complete bus isolation per AEC-Q100 suspend requirements.
