Product details
Overview
NXB0104GU12X from Nexperia is a 4-bit dual-supply translating transceiver with auto-direction sensing and 3-state outputs, enabling bidirectional voltage level translation between 1.2 V–3.6 V (VCC(A)) and 1.65 V–5.5 V (VCC(B)) domains. It features 12-pin XQFN packaging, IOFF partial power-down protection, and operates across −40 °C to +125 °C. Used in mixed-voltage SoC-to-peripheral interfaces such as 1.8 V microcontroller GPIOs driving 3.3 V sensors.
For engineers reviewing the NXB0104GU12X datasheet, NXB0104GU12X pinout, NXB0104GU12X application, or NXB0104GU12X equivalent, key selection criteria include auto-direction operation without external control, guaranteed IOFF leakage < ±10 μA at power-down, propagation delay ≤9.5 ns (A→B, VCC(A)=1.8 V/VCC(B)=5.0 V, −40 °C to +125 °C), and ESD robustness (15 kV HBM on B port).
Technical Context
The NXB0104GU12X implements edge-triggered one-shot circuitry per I/O channel to detect data direction automatically-no external DIR signal required. Each A/B pair uses complementary PMOS/NMOS output drivers with transient acceleration during transitions, achieving typical output impedance of 40 Ω at VCCO = 3.3–5.0 V.
Its IOFF architecture disables outputs when either VCC(A) or VCC(B) is at GND, blocking backflow current. Input thresholds are referenced to respective supply rails (VIH ≥ 0.65×VCCI; VIL ≤ 0.35×VCCI), and all I/Os tolerate up to 5.5 V regardless of supply state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - supports interface with 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V logic domains |
| VCC(B) Range | 1.65 V to 5.5 V - enables translation to 1.8 V/2.5 V/3.3 V/5.0 V systems |
| Propagation Delay (A→B) | ≤9.5 ns max at −40 °C to +125 °C, VCC(A)=1.8 V/VCC(B)=5.0 V - ensures timing compliance in 40 Mbps data paths |
| IOFF Leakage Current | ±10 μA max at full temperature range - prevents damaging back-current during partial power-down |
| HBM ESD Rating (B port) | 15 kV per JS-001 Class 3B - protects against handling-induced discharge in high-voltage I/O zones |
| Operating Temperature | −40 °C to +125 °C - qualified for automotive under-hood and industrial control environments |
| Package | XQFN12 (SOT1174-1), 1.70 × 2.0 × 0.50 mm - ultra-compact footprint for space-constrained PCB layouts |
Pinout & Package
XQFN12 package (SOT1174-1) with 0.4 mm pitch, exposed thermal pad (non-soldered by default), and 12 terminals in 3×4 array. Pin 1 index located at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply rail for A-side I/Os (1.2–3.6 V); powers OE input and A1–A4 buffers |
| 2–5 | A1–A4 | Bidirectional data pins referenced to VCC(A); auto-sense direction via internal one-shots |
| 6 | GND | Common reference ground (0 V); mandatory connection for signal integrity and ESD path |
| 7–10 | B1–B4 | Bidirectional data pins referenced to VCC(B); tolerate up to 5.5 V inputs independent of VCC(B) |
| 11 | VCC(B) | Supply rail for B-side I/Os (1.65–5.5 V); powers B1–B4 output drivers |
| 12 | OE | Active-HIGH output enable (referenced to VCC(A)); LOW forces all I/Os into high-impedance OFF-state |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external DIR control line; detects data flow direction via edge-triggered one-shot circuitry on each I/O pair |
| IOFF partial power-down | Blocks backflow current when either VCC(A) or VCC(B) is off; IOFF leakage ≤ ±10 μA over full temperature range |
| Wide voltage tolerance | A/B port inputs accept up to 5.5 V regardless of supply state - simplifies hot-swap and mixed-rail system design |
| High ESD robustness | B-port HBM rating of 15 kV (JS-001 Class 3B) - exceeds IEC 61000-4-2 Level 4 for industrial and automotive applications |
| Low dynamic power | CPD ≤ 30 pF (B port, A→B direction, VCC(B)=5.0 V) - reduces switching power in high-frequency data buses |

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 |
|---|---|---|---|
| TXS0104E | 4-bit, auto-direction, but only supports VCCA = 1.2–3.6 V and VCCB = 1.65–5.5 V - identical voltage ranges; lacks IOFF circuitry | No partial power-down capability; unsuitable for systems requiring back-current blocking during rail sequencing | Select TXS0104E only if IOFF is not required and lower cost is prioritized over safety-critical isolation. |
| SN74AVC4T245 | 4-bit, dual-supply, but requires explicit DIR pin control; no auto-sensing; higher ICC (up to 40 μA vs. 10 μA typical for NXB0104) | Demands additional GPIO and firmware coordination for direction management; increases PCB routing complexity | Choose SN74AVC4T245 when deterministic direction control is preferred over autonomous operation and layout simplicity. |
Compared with TXS0104E and SN74AVC4T245, the NXB0104GU12X uniquely combines auto-direction sensing, IOFF protection, and ultra-small XQFN12 packaging - delivering both functional simplification and reliability in thermally constrained, multi-rail embedded systems.

FAQ
What is the maximum capacitive load the NXB0104GU12X can drive reliably?
The device supports ≤30 pF total load capacitance on B-side outputs (per Table 13, VCC(B)=5.0 V) while maintaining specified propagation delay and transition time. Exceeding this risks incomplete rail transitions due to one-shot pulse duration limits; layout best practices include short traces (<5 cm) and avoiding stubs or connectors with >2 pF parasitic capacitance.
Can VCC(A) and VCC(B) be powered in any sequence during startup?
Yes - unlike many translators, the NXB0104GU12X tolerates VCC(A) ≥ VCC(B) during power-up without damage. Its architecture ensures safe operation regardless of ramp order, eliminating need for power sequencing circuits or supervisor ICs in multi-rail systems.
Does the OE pin require a pull-up resistor?
No - OE is referenced to VCC(A) and has no internal pull-up. To ensure defined state at power-on, OE must be actively driven HIGH (to VCC(A)) or pulled up externally via ≥10 kΩ resistor; floating OE may cause undefined I/O behavior during initialization.
How does the auto-direction sensing behave with slow-rising or noisy signals?
The one-shot circuitry triggers on edges ≥1 V/ns (Δt/ΔV spec). Signals slower than this threshold may fail to activate direction detection, causing bus contention. For marginal edges, add series resistance (≤100 Ω) or RC filtering to sharpen transitions without violating input voltage limits.
