Product details
Overview
74AVC4T774BQ-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 interfacing 1.2 V SoCs with 3.3 V sensor buses.
For engineers reviewing the 74AVC4T774BQ-Q100 datasheet, 74AVC4T774BQ-Q100 pinout, 74AVC4T774BQ-Q100 application, or 74AVC4T774BQ-Q100 equivalent, key selection criteria include bidirectional voltage translation capability, AEC-Q100 Grade 1 qualification, IOFF-enabled suspend mode, 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 separate DIRn control and shared OE. Signal flow direction per channel is determined solely by DIRn state: HIGH enables An→Bn, LOW enables Bn→An. Both supply rails are fully decoupled-An, DIRn, and OE reference VCC(A); Bn pins reference VCC(B).
IOFF circuitry actively disables outputs and blocks backflow current when either VCC(A) or VCC(B) is at GND, forcing all An and Bn terminals into high-impedance OFF-state during suspend mode. Static and dynamic parameters-including VIH/VIL thresholds, propagation delays, and power dissipation capacitance-are specified across -40 °C to +125 °C and full 0.8 V–3.6 V supply ranges.
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 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 - achievable for ≥1.8 V to 3.3 V translation, enabling high-speed inter-domain communication |
| Propagation Delay | An→Bn: 0.2 ns min / 12.1 ns max (-40 °C to +125 °C); Bn→An: 0.2 ns min / 12.8 ns max - ensures timing predictability in mixed-voltage bus arbitration |
| IOFF Leakage | ±5 μA max (VCC = 0 V) - guarantees safe isolation during partial power-down without damaging backflow current |
| ESD Protection | HBM: >8000 V; CDM: >1500 V - meets stringent automotive ESD robustness requirements per AEC-Q100 |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood and ADAS module deployment per AEC-Q100 Grade 1 |
| Package | DHVQFN16 (SOT763-1), 2.5 × 3.5 × 0.85 mm - thermally enhanced, leadless package suitable for space-constrained automotive PCBs |
Pinout & Package
DHVQFN16 (SOT763-1) package: 2.5 mm × 3.5 mm body, 0.85 mm height, exposed thermal pad (non-soldered or floating/GND), 16 terminals, no leads.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 7, 8 | DIR1–DIR4 | Direction control inputs referenced to VCC(A); HIGH = An→Bn, LOW = Bn→An per channel |
| 3–6 | A1–A4 | Data I/O ports referenced to VCC(A); bidirectional under DIRn and OE control |
| 9 | OE | Active-low output enable; when HIGH, all A/B ports enter high-impedance state |
| 10 | GND | Ground reference (0 V); required for bias and noise return path |
| 11–14 | B1–B4 | Data I/O ports referenced to VCC(B); bidirectional under DIRn and OE control |
| 15 | VCC(B) | Supply for B-side I/O; sets voltage reference and drive strength for B1–B4 |

Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Level Translation | Four independent channels translate signals between any pair of 0.8 V–3.6 V supplies without external components |

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 |
|---|---|---|---|
| SN74AVC4T245QPWRQ1 | Single DIR input controls all four channels; no per-channel DIRn; 14-pin TSSOP package | Lacks independent channel direction control; unsuitable for asymmetric bidirectional protocols requiring per-lane DIR | Select only when unified direction control suffices and TSSOP footprint is acceptable |
| TXS0104EPWR | Auto-direction sensing (no DIR pins); higher VOL at 1.2 V (0.4 V typ); not AEC-Q100 qualified | Cannot replace in safety-critical automotive systems; lacks suspend-mode IOFF guarantee | Not recommended for AEC-Q100 applications; use only in industrial non-automotive designs |
Compared with SN74AVC4T245QPWRQ1 and TXS0104EPWR, the 74AVC4T774BQ-Q100 uniquely provides per-channel DIR control, AEC-Q100 Grade 1 qualification, and guaranteed IOFF behavior-making it the sole choice for automotive domain controllers requiring independent lane-level direction management and fail-safe power-down.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
No maximum differential is specified-the device supports independent operation across its full 0.8 V to 3.6 V range on each rail. For example, VCC(A) = 1.2 V and VCC(B) = 3.3 V is valid and characterized up to 380 Mbit/s. Absolute maximum ratings limit each supply to -0.5 V to +4.6 V relative to GND, but no inter-rail voltage constraint applies beyond those individual limits.
How does IOFF behave when only VCC(A) is powered?
When VCC(A) = 3.6 V and VCC(B) = 0 V (GND), the device enters suspend mode: all A1–A4 and B1–B4 pins go high-impedance, and IOFF leakage is limited to ±5 μA max. This prevents back-driving the unpowered B-side bus, protecting downstream 3.3 V peripherals from damage or unintended activation.
Can DIRn and OE be driven from different voltage domains?
No-DIR1–DIR4 and OE inputs are referenced exclusively to VCC(A) and must be driven by signals compatible with VCC(A)'s voltage range (0.8 V–3.6 V). Driving them from VCC(B) or another domain violates input voltage specifications and may cause malfunction or damage. Level-shifting these control signals is the system designer's responsibility.
Is the exposed thermal pad electrically connected?
The exposed pad in the DHVQFN16 (SOT763-1) package has no internal electrical connection. Per datasheet note, it may remain floating or be connected to GND-but must never be soldered to a net requiring electrical continuity. Its purpose is purely thermal enhancement, not signal or power routing.
