Product details
Overview
74AVC4T3144GU12X from Nexperia is a 4-bit dual-supply level-translating buffer with 3-state outputs, configured for asymmetric bidirectional translation: three A-side inputs (A1–A3) translate to B-side outputs (YB1–YB3), and one B-side input (B4) translates to A-side output (YA4). It operates across independent VCC(A) and VCC(B) rails from 0.8 V to 3.6 V, supports 380 Mbit/s data rates at ≥1.8 V → 3.3 V, and features IOFF circuitry for partial power-down protection in mixed-voltage SoC interconnects.
For engineers reviewing the 74AVC4T3144GU12X datasheet, 74AVC4T3144GU12X pinout, 74AVC4T3144GU12X application, or 74AVC4T3144GU12X equivalent, this device is selected for low-voltage I/O bridging between 1.2 V FPGA banks and 3.3 V peripherals, high-speed USB/SDIO voltage domain isolation, and suspend-mode-safe logic interfacing in battery-powered edge nodes.
Technical Context
The device implements independent supply-referenced input/output domains: OE, A1–A3, and YA4 are referenced to VCC(A); YB1–YB3 and B4 to VCC(B). Its IOFF circuit disables all outputs when either VCC rail drops to GND, preventing backflow current during power sequencing or sleep transitions.
Propagation delay is asymmetric by design: An→YBn paths exhibit faster timing (e.g., 5.9 ns typical at VCC(A)=2.5 V/VCC(B)=3.3 V) than B4→YA4 (12.0 ns), reflecting its optimized 3:1 directional translation architecture. Suspend mode activates automatically if VCC(A) = 0 V or VCC(B) = 0 V, forcing all outputs to high-impedance regardless of OE state.
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 direct interface between sub-1 V AI accelerators and 3.3 V legacy peripherals without external level-shifting components. |
| Max Data Rate | 380 Mbit/s - achievable only for ≥1.8 V → 3.3 V translation, supporting high-speed SDIO 4-bit mode or parallel camera sensor interfaces. |
| IOFF Leakage | ±1 μA max at VCC = 0 V - ensures <1 µA backfeed current during power-down, critical for battery runtime in always-on IoT sensors. |
| ESD Rating | HBM >8 kV, CDM >1 kV - meets industrial IEC 61000-4-2 Level 4 immunity requirements without added TVS diodes. |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive control modules and industrial motor drives. |
| Propagation Delay | An→YBn: 5.9 ns typ @ 2.5 V→3.3 V; B4→YA4: 12.0 ns typ - asymmetry matches typical system data flow (e.g., host→device commands vs. device→host status). |
| Power Dissipation | CPD = 11.2 pF @ 3.3 V - enables accurate dynamic power estimation for thermal budgeting in dense PCB layouts. |
Pinout & Package
XQFN12 (SOT1174-1) package: 1.70 × 2.00 × 0.50 mm body, 12-terminal no-lead construction with exposed thermal pad; suitable for space-constrained portable electronics and high-density automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply rail for A-side logic (A1–A3, YA4, OE); defines input thresholds and output drive strength on A port. |
| 2–4, 7 | A1, A2, A3, B4 | Data inputs: A1–A3 referenced to VCC(A); B4 referenced to VCC(B) - enables bidirectional cross-rail signal routing. |
| 5 | YA4 | A-side output driven by B4 input - sole reverse-direction path, used for status/ACK signals from B-domain peripherals. |
| 6 | GND | Common reference for all I/O and supply pins; must be low-inductance connection to minimize ground bounce in high-speed switching. |
| 8–10 | YB1, YB2, YB3 | B-side outputs driven by A1–A3 - primary forward-direction paths for command/data from A-domain controllers. |
| 11 | VCC(B) | Supply rail for B-side logic (YB1–YB3, B4); independent of VCC(A), enabling true dual-voltage operation. |
| 12 | OE | Active-LOW output enable referenced to VCC(A); asserts high-impedance on all outputs when HIGH, enabling bus sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric Translation | 3 forward (A→B) + 1 reverse (B→A) channels - eliminates need for two separate translators in mixed-voltage microcontroller-to-peripheral links. |
| IOFF Partial Power-Down | Outputs disable automatically if VCC(A) = 0 V or VCC(B) = 0 V - prevents current leakage during brown-out or controlled shutdown sequences. |
| Suspend Mode | All outputs enter high-Z when either supply is at GND - guarantees safe state during hot-plug events or power sequencing faults. |
| JEDEC Compliance | Validated across JESD8-12 through JESD8-B standards - ensures interoperability with memory, FPGA, and ASIC I/O cells across 0.8 V–3.6 V logic families. |
| Low Dynamic Power | CPD = 9.3–11.2 pF - reduces switching power by >30% versus comparable 74LVC devices at 3.3 V, extending battery life in wearables. |
Applications
| Industrial PLC I/O Module | Automotive ADAS Camera Interface |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVCH4T245PWR | 4-bit bidirectional translator with auto-direction sensing; no fixed A/B channel assignment; higher ICC (max 100 µA vs. 70 µA) | Requires external direction-control logic for unidirectional use cases; less optimal for asymmetric 3:1 signal mapping | Select when bidirectional data flow (e.g., I²C, SPI) dominates; avoid when fixed forward/reverse channel separation is required. |
| TXB0104RGYR | 4-bit auto-bidirectional translator; no OE pin; relies on bus activity for direction detection; lower max speed (100 Mbit/s) | Cannot support OE-controlled bus arbitration; unsuitable for systems requiring deterministic 3-state control during reset | Choose for simple push-pull buses like GPIO expansion; reject for applications needing explicit OE-driven bus isolation or >100 Mbit/s throughput. |

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet specifies independent operating ranges (0.8 V–3.6 V each) but does not define a maximum differential. Absolute maximum ratings allow VCC(A) and VCC(B) to operate at opposite extremes (e.g., 0.8 V and 3.6 V simultaneously) without damage, provided IOFF and suspend mode conditions are respected. No derating is required for ΔV up to 2.8 V.
Can OE be driven from a different voltage domain than VCC(A)?
No. Pin description explicitly states OE is referenced to VCC(A); applying voltage outside 0 V to VCC(A) risks violating absolute maximum input voltage limits (VI = −0.5 V to VCC(A) + 0.5 V). OE must be controlled by logic operating at the same VCC(A) level to ensure correct threshold detection and avoid latch-up.
How does suspend mode behave when only VCC(A) is powered?
When VCC(A) = 3.6 V and VCC(B) = 0 V, the device enters suspend mode: all B-side outputs (YB1–YB3) and YA4 go high-impedance regardless of OE state, and A-side inputs (A1–A3) present ≤±5 µA leakage. This prevents back-driving of the unpowered B-rail, protecting downstream 3.3 V circuitry.
Is the 380 Mbit/s data rate guaranteed across the full −40 °C to +125 °C range?
No. The 380 Mbit/s rating applies only under specific conditions: VCC(A) ≥ 1.8 V, VCC(B) = 3.3 V, Tamb = 25 °C, and CL = 15 pF. At +125 °C, maximum usable rate drops to 200 Mbit/s for the same voltage combination due to increased propagation delay (Table 14), requiring timing margin validation in worst-case thermal environments.
