Product details
Overview
74AVC4T774PW from Nexperia is a 4-bit dual-supply translating transceiver enabling bidirectional level translation between independent voltage domains (VCC(A): 0.8–3.6 V; VCC(B): 0.8–3.6 V), featuring four independent DIR controls, active-low OE, and IOFF partial power-down protection. It supports 0.8 V ↔ 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V translation in mixed-voltage SoC interconnects.
For engineers reviewing the 74AVC4T774PW datasheet, 74AVC4T774PW pinout, 74AVC4T774PW application, or 74AVC4T774PW equivalent, key selection criteria include per-channel direction control, suspend-mode isolation under partial power-down, JEDEC-compliant voltage node compatibility, and 380 Mbit/s max data rate for 1.8 V ↔ 3.3 V translation.
Technical Context
This device implements eight independent I/O ports (A1–A4, B1–B4) with per-bit directional control via DIR1–DIR4, allowing simultaneous A→B and B→A traffic on different channels. Each channel operates with separate supply references: An/OE/DIRn tied to VCC(A), Bn tied to 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 system suspend. Propagation delays range from 0.2 ns (min, 3.3 V → 3.3 V) to 15.6 ns (max, -40 °C to +125 °C, low-voltage conditions), with asymmetric timing depending on direction and supply pairing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A) and VCC(B): 0.8 V to 3.6 V - enables translation across 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 only for ≥1.8 V ↔ 3.3 V translation; defines maximum usable clock frequency in high-speed bus bridging |
| IOFF Protection | Active during partial power-down - disables outputs and blocks damaging backflow current when either supply is at GND |
| Propagation Delay | 0.2 ns to 15.6 ns - varies by direction (An→Bn vs Bn→An), supply pair, temperature, and load; critical for timing closure in multi-domain interfaces |
| ESD Rating | HBM >8000 V, CDM >1500 V - exceeds JEDEC JS-001 Class 3B and JS-002 Class C3, supporting robust handling in automated assembly |
| Operating Temp | -40 °C to +125 °C - qualified for automotive under-hood and industrial control applications requiring extended thermal margin |
| Package | TSSOP16 (SOT403-1), 4.4 mm body width - surface-mount package with 0.65 mm pitch, compatible with standard reflow profiles and AOI inspection |
Pinout & Package
TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, 4.4 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 7, 8 | DIR1–DIR4 | Per-channel direction control inputs referenced to VCC(A); HIGH = An→Bn, LOW = Bn→An |
| 3–6 | A1–A4 | Bidirectional data ports referenced to VCC(A); function as input or output based on corresponding DIR state |
| 9 | OE | Active-low output enable; drives all A/B ports to high-impedance when HIGH |
| 10 | GND | Common ground reference for all internal circuitry and ESD structures |
| 11–14 | B4–B1 | Bidirectional data ports referenced to VCC(B); order reversed per pinout diagram (B4=11, B3=12, B2=13, B1=14) |
| 15 | VCC(B) | Supply for B-side I/Os (B1–B4); sets logic thresholds and drive strength for B-port signals |
| 16 | VCC(A) | Supply for A-side I/Os (A1–A4), DIR1–DIR4, and OE; defines input thresholds and output swing for A-port |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-bit direction control | Four DIR inputs allow concurrent A→B and B→A data flow on separate channels without global bus arbitration |
| Dual-supply domain isolation | VCC(A) and VCC(B) operate independently; no internal level-shifting circuitry required - simplifies PCB routing and reduces noise coupling |
| Suspend-mode high-impedance | Both A and B ports enter guaranteed OFF-state when either VCC drops to GND - eliminates leakage paths in sleep-mode systems |
| JEDEC-compliant voltage support | Fully compliant with JESD8-12 (0.8–1.3 V), JESD8-11 (0.9–1.65 V), JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), and JESD8-B (2.7–3.6 V) |
| Low dynamic power dissipation | CPD as low as 0.2 pF per A/B port in output-enabled mode at 0.8 V - minimizes switching power in battery-sensitive applications |
Applications
| Mobile SoC Interconnect | Industrial PLC Backplane |

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 |
|---|---|---|---|
| SN74AVC4T245PWR | Single DIR control for all 4 channels; no per-bit direction capability | Requires external logic for independent lane direction; less flexible in heterogeneous bus topologies | Select when cost sensitivity outweighs need for per-lane control and board space allows added logic |
| TXB0104PWR | Auto-direction sensing (no DIR pins); higher typical propagation delay (≥15 ns) | Unsuitable for bidirectional protocols requiring deterministic direction timing (e.g., SPI half-duplex with shared lines) | Select only for simple GPIO expansion where direction changes infrequently and latency is non-critical |
Compared with SN74AVC4T245PWR and TXB0104PWR, the 74AVC4T774PW uniquely delivers per-channel DIR control and lowest propagation delay in high-voltage translation (e.g., 1.8 V ↔ 3.3 V), making it optimal for timing-critical, mixed-domain SoC interconnects.

FAQ
Can 74AVC4T774PW translate between 0.8 V and 3.3 V simultaneously?
Yes - VCC(A) may be set to 0.8 V while VCC(B) is set to 3.3 V, enabling direct translation. Inputs referenced to VCC(A) accept up to 3.6 V, and B-side outputs swing rail-to-rail relative to VCC(B). This configuration supports 100 Mbit/s data rate per channel.
What happens to B-port outputs when VCC(A) = 0 V and VCC(B) = 1.8 V?
In this suspend condition, the IOFF circuit forces all B-port outputs into high-impedance OFF-state regardless of DIR or OE states. Input leakage remains ≤ ±5 μA, preventing unintended loading of the 1.8 V bus.
Is OE pin active-high or active-low?
The OE pin is active-low: logic LOW enables A/B port transmission per DIR settings; logic HIGH places all A and B ports in high-impedance state. OE is referenced to VCC(A) and has VIH = 0.65×VCC(A) min at 1.1–1.95 V operation.
Does 74AVC4T774PW support hot insertion?
Yes - its IOFF circuit and 3.6 V-tolerant inputs (on A-side) allow safe connection to a live 3.3 V bus while VCC(A) is ramping. The device enters suspend mode until both supplies stabilize, eliminating glitch risk during power sequencing.
