Product details
Overview
74AVC4T774GUX 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 circuitry for partial power-down. Used in mixed-voltage SoC interconnects, such as FPGA-to-ASIC data buses operating at 1.2 V/1.8 V or 1.8 V/3.3 V.
For engineers reviewing the 74AVC4T774GUX datasheet, 74AVC4T774GUX pinout, 74AVC4T774GUX application, or 74AVC4T774GUX equivalent, key selection criteria include per-channel direction control granularity, suspend-mode isolation when either supply is grounded, JEDEC-compliant low-voltage operation down to 0.8 V, and verified 380 Mbit/s data rate for ≥1.8 V ↔ 3.3 V translation.
Technical Context
The device implements four independent 1-bit bidirectional transceivers, each with dedicated DIRn input controlling signal flow direction (An ↔ Bn). Direction logic is referenced to VCC(A); OE is active-low and also referenced to VCC(A). Both A-side and B-side I/Os are 3-state controllable and tolerate up to 3.6 V regardless of supply level.
IOFF circuitry ensures high-impedance OFF-state and blocks damaging backflow current during partial power-down. In suspend mode (VCC(A) = GND or VCC(B) = GND), all An and Bn pins enter high-impedance state-enabling safe hot-plug and power-gating scenarios in battery-backed or modular systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 0.8 V to 3.6 V: Enables interface between sub-1 V logic (e.g., advanced CPU cores) and 3.3 V peripherals. |
| VCC(B) Range | 0.8 V to 3.6 V: Independent supply allows asymmetric translation (e.g., 1.2 V FPGA ↔ 2.5 V memory controller). |
| Max Data Rate | 380 Mbit/s: Valid for ≥1.8 V ↔ 3.3 V translation; supports DDR-like timing in high-speed interconnects. |
| IOFF Leakage | ±1 μA max at 25 °C: Ensures <10 μW static power in powered-down domains, critical for ultra-low-power suspend states. |
| Propagation Delay | 0.2 ns to 12.8 ns (varies by VCC pair): Measured from DIR/OE transition to valid output; enables timing-critical bus arbitration. |
| ESD Rating | HBM >8 kV, CDM >1.5 kV: Robust enough for handling in automated assembly and field-replaceable modules. |
| Operating Temp | −40 °C to +125 °C: Qualified for automotive under-hood and industrial motor-control environments. |
Pinout & Package
XQFN16 package (SOT1161-1): 1.80 × 2.60 × 0.50 mm, 16-terminal no-lead quad flat, thermal-enhanced, exposed die pad (non-soldered or floating).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | Data I/O (VCC(A)-referenced) | Connect to low-voltage domain (e.g., 1.2 V processor bus); tolerate up to 3.6 V inputs. |
| B1–B4 | Data I/O (VCC(B)-referenced) | Interface to higher-voltage domain (e.g., 3.3 V sensor hub); fully isolated from A-side supply. |
| DIR1–DIR4 | Per-channel direction control | Independent control per bit pair enables mixed-direction data flow on same bus (e.g., command + response). |
| OE | Active-low output enable | Global 3-state control; asserts simultaneously across all 8 I/Os to isolate both domains. |
| VCC(A) | Supply for A-side logic | Powers DIRn, OE, and A-port I/O drivers; defines logic thresholds for A-side signals. |
| VCC(B) | Supply for B-side logic | Powers B-port I/O drivers only; decoupled from A-side supply for true dual-rail operation. |
| GND | Common reference | Single ground plane required; no separate analog/digital GND pins. |
Key Features
| Feature | Design Value |
|---|---|
| Per-bit direction control | Four independent DIR inputs allow simultaneous bidirectional data transfer on different lanes (e.g., A→B on lane 1, B→A on lane 2). |
| IOFF partial power-down | Prevents back-current when VCC(A) or VCC(B) is 0 V-enables safe power sequencing in multi-rail systems without external isolation switches. |
| Suspend mode | Automatic high-Z on all I/Os when either supply drops to GND-eliminates need for external power-good monitoring in hot-swap designs. |
| JEDEC compliance | Meets JESD8-12 (0.8–1.3 V) through JESD8-B (2.7–3.6 V), ensuring interoperability across legacy and next-gen low-voltage standards. |
| 3.6 V-tolerant inputs | All A-side inputs accept 0–3.6 V regardless of VCC(A) level-simplifies interfacing with legacy 3.3 V outputs into sub-1 V domains. |
Applications
| Mobile SoC Interconnect | FPGA-to-ASIC Bridge |

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 |
|---|---|---|---|
| SN74AVC4T245RTER | Single DIR input controls all 4 channels; no per-bit direction control; identical VCC range and speed. | Less flexible for mixed-direction protocols; suitable only where all lanes share same direction. | Select when system uses synchronous full-duplex or half-duplex modes-not for asymmetric command/response buses. |
| TXS0104EPWR | Auto-direction sensing (no DIR pins); lower max speed (60 Mbit/s); supports 1.2 V ↔ 3.3 V only. | Eliminates DIR routing but cannot handle concurrent bidirectional traffic; unsuitable for high-speed or mixed-VCC topologies. | Choose only for simple, low-speed, single-direction-per-bus applications where DIR pin count must be minimized. |
Compared with SN74AVC4T245RTER and TXS0104EPWR, the 74AVC4T774GUX uniquely delivers per-channel direction control, full 0.8–3.6 V dual-rail flexibility, and 380 Mbit/s performance-making it optimal for complex, mixed-voltage, high-bandwidth interconnects requiring precise timing and power-state coordination.

FAQ
What is the minimum recommended VCC(A) and VCC(B) for guaranteed operation?
The device is fully specified from 0.8 V to 3.6 V for both supplies. At 0.8 V, propagation delay increases to ~14.5 ns and maximum data rate drops to 100 Mbit/s (0.8 V ↔ 1.2 V). For reliable 380 Mbit/s operation, use VCC(A) ≥ 1.8 V and VCC(B) ≥ 3.3 V per datasheet Table 2.
Can OE be driven from a different voltage domain than VCC(A)?
No. OE is strictly referenced to VCC(A) and must be driven within 0 V to VCC(A). Driving OE from VCC(B) or an external rail violates absolute maximum ratings and may cause latch-up or undefined behavior. Use a local level shifter if OE control originates from the B-side domain.
How does suspend mode 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 B1–B4 pins go high-impedance, and A1–A4 remain high-Z due to internal IOFF activation. No current flows between domains, and OE/DIR inputs are ignored-ensuring complete electrical isolation.
Is the exposed thermal pad on the XQFN16 package electrically connected?
No. The exposed pad (terminal 1 index area) has no internal electrical connection. Per datasheet Section 6.1, it may be left floating or connected to GND for thermal enhancement-but must not be soldered to a voltage net other than GND, and no electrical requirement exists for soldering.
