Product details
Overview
74LVC4T3144PWJ from Nexperia is a 4-bit dual-supply level-translating buffer with 3-state outputs, configured for bidirectional voltage translation: three A-side inputs (A1–A3) and one B-side input (B4) drive corresponding YBn and YA4 outputs referenced to VCC(B) and VCC(A), respectively. It supports independent supply rails from 1.2 V to 5.5 V per side, delivers ±24 mA output drive at 3.0 V, operates across –40 °C to +125 °C, and enables partial power-down via IOFF circuitry - used in mixed-voltage FPGA-to-ASIC interconnects.
For engineers reviewing the 74LVC4T3144PWJ datasheet, 74LVC4T3144PWJ pinout, 74LVC4T3144PWJ application, or 74LVC4T3144PWJ equivalent, key selection criteria include asymmetric translation directionality (3× A→B, 1× B→A), suspend-mode behavior during single-rail power loss, OE-referenced-to-VCC(A) control logic, and dynamic performance up to 200 Mbps in 3.3 V → 5.0 V translation.
Technical Context
The device implements fixed-direction level shifting: A1–A3 and OE are referenced to VCC(A); YB1–YB3 and B4 are referenced to VCC(B); YA4 is A-side output referenced to VCC(A). This asymmetry enables simultaneous translation from low-voltage logic (e.g., 1.8 V FPGA I/O) to high-voltage peripherals (e.g., 5 V sensors) while preserving one reverse path for status feedback.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) drops to GND, preventing backflow current and enabling safe hot-swap or partial system power-down. Propagation delays range from 0.6 ns (5 V → 5 V) to 22 ns (1.2 V → 1.2 V), with disable/enable times tightly bounded (e.g., tdis = 6.8 ns max at 5.0 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 1.2 V to 5.5 V; VCC(B): 1.2 V to 5.5 V - enables direct interface between disparate logic families without external level shifters. |
| Translation Direction | 3× A→B (A1–A3 → YB1–YB3), 1× B→A (B4 → YA4) - supports primary data flow plus dedicated status/acknowledge return path. |
| Max Data Rate | 200 Mbps (3.3 V → 5.0 V) - sufficient for high-speed serial control bus signaling in industrial PLC modules. |
| Output Drive | ±24 mA at VCC = 3.0 V - drives 50 Ω transmission lines or multiple 74LVC inputs without buffering. |
| IOFF Leakage | ±2 μA max per port during suspend mode - ensures <1 μA total system leakage when one rail is powered down. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor drives. |
| ESD Rating | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events in automated assembly. |
Pinout & Package
TSSOP14 package (SOT402-1), 4.4 mm body width, 14-pin thin shrink small outline - compatible with standard 0.65 mm pitch PCB assembly and reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, VCC(A) | A-side supply rail | Powers A-port inputs (A1–A3), OE, and YA4 output - defines logic thresholds and output swing for A-side signals. |
| 2–4, A1–A3 | A-side data inputs | Accept 0–5.5 V inputs regardless of VCC(A); translate to YB1–YB3 referenced to VCC(B). |
| 5, YA4 | A-side output | Driven by B4 input (VCC(B)-referenced); provides reverse-path signal to A-side logic with VCC(A) swing. |
| 6–7, GND | Ground reference | Common return for both supply domains; must be low-impedance to minimize ground bounce during switching. |
| 8, B4 | B-side data input | Referenced to VCC(B); drives YA4 output referenced to VCC(A) - sole reverse-direction path. |
| 9, n.c. | No-connect terminal | Internally unconnected; must remain floating or tied to GND per layout best practices. |
| 10–12, YB3–YB1 | B-side outputs | 3-state outputs referenced to VCC(B); driven by A1–A3 with full VCC(B) swing and drive strength. |
| 13, VCC(B) | B-side supply rail | Powers B-port outputs (YB1–YB3) and B4 input - sets output voltage domain and noise margin for B-side loads. |
| 14, OE | Output enable (active LOW) | Referenced to VCC(A); asserts high-impedance on all outputs when HIGH - enables bus sharing and power gating. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric translation topology | 3 forward paths (A→B) + 1 reverse path (B→A) enables master-slave control with status feedback in single-package solution. |
| IOFF-enabled partial power-down | Prevents damaging back-current when VCC(A) or VCC(B) is at 0 V - eliminates need for external isolation FETs in modular systems. |
| Wide voltage interoperability | Supports JEDEC standards JESD8-11A through JESD12-6 - interoperates with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic families without configuration. |
| Low static power | 25–30 μA typical ICC(A)+ICC(B) - reduces quiescent load in battery-backed subsystems and always-on monitoring circuits. |
| Suspend-mode robustness | All outputs enter high-Z when either supply is at GND - guarantees no signal contention during brown-out or staged power sequencing. |
Applications
| Industrial PLC I/O Modules | FPGA-to-Microcontroller Interfacing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply level translating buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVCH4T245RGE | 4-bit bidirectional translator (A↔B), symmetric 4×4 paths, no fixed A→B/B→A split | Requires external direction control; lacks dedicated reverse-path optimization for status feedback | Select when full bidirectionality is required and OE-controlled direction logic is acceptable. |
| TXB0104PWR | Auto-sensing bidirectional translator; no OE pin; relies on data edge detection for direction | Unsuitable for synchronous control buses; introduces variable latency and potential metastability on idle lines | Select only for simple GPIO expansion where timing determinism is non-critical. |
Compared with SN74AVCH4T245RGE and TXB0104PWR, the 74LVC4T3144PWJ offers deterministic, OE-gated asymmetric translation ideal for master-slave control architectures - delivering lower latency on forward paths and guaranteed reverse-path timing without direction-control overhead.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet specifies independent absolute maximum ratings: VCC(A) and VCC(B) each tolerate –0.5 V to +6.5 V relative to GND. No differential limit is defined - operation is valid with VCC(A) = 1.2 V and VCC(B) = 5.5 V simultaneously, provided both remain within their individual limits and GND is common.
Can OE be driven from a different voltage domain than VCC(A)?
No - OE is strictly referenced to VCC(A) and must be driven between 0 V and VCC(A). Driving OE from VCC(B) or another rail violates the input voltage specification (VI ≤ 5.5 V, but VIH/VIL thresholds scale with VCC(A)) and may cause undefined output states or increased leakage.
How does suspend mode behave when only VCC(A) is powered?
When VCC(A) = 5.5 V and VCC(B) = 0 V, the device enters suspend mode: YB1–YB3 and YA4 go high-impedance, and IOFF limits leakage to ±2 μA. OE remains functional (if driven), but outputs stay disabled until VCC(B) rises above threshold - ensuring safe isolation of the B-side bus.
Is the 74LVC4T3144PWJ suitable for driving 50 Ω transmission lines?
Yes - with ±24 mA output drive at 3.0 V, it can directly drive 50 Ω lines terminated at VCC(B) or VCC(A), achieving near-full swing with <10% overshoot. For 100 Mbps+ signals, maintain controlled impedance routing and minimize stub length to preserve signal integrity.
