Product details
Overview
NXS0102 from Nexperia is a 2-bit dual-supply translating transceiver with auto-direction sensing and open-drain I/O, enabling bidirectional level translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)) domains. It supports up to 24 Mbps data rate in push-pull mode, features integrated 10 kΩ pull-ups per port, and includes IOFF circuitry for partial power-down protection. It is used in I²C and 1-wire bus interfacing between mixed-voltage SoCs and peripherals in smartphones and tablets.
For engineers reviewing the NXS0102 datasheet, NXS0102 pinout, NXS0102 application, or NXS0102 equivalent, key selection considerations include its auto-sensing direction control, dual-rail supply flexibility, guaranteed operation from –40 °C to +125 °C, and compatibility with open-drain signaling topologies requiring no external direction control logic.
Technical Context
The NXS0102 implements a switch-type voltage translation architecture using pass-gate transistors biased at ~VCC(A) + Vth, eliminating need for external direction control. Its one-shot edge-acceleration circuit activates on input transitions exceeding 0.5×VCCI to reduce tPLH/tPHL, delivering sub-8 ns propagation delays across voltage combinations.
Internal 10 kΩ pull-up resistors on both A and B ports reference VCC(A) and VCC(B) respectively, and are disabled when OE is LOW. The IOFF circuit ensures <±12 μA power-off leakage when either supply is at 0 V, preventing backflow current during partial power-down sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - powers A-side I/O and OE; must be ≤ VCC(B) for safe operation |
| VCC(B) Range | 2.3 V to 5.5 V - powers B-side I/O; enables translation to 5 V logic domains |
| Max Data Rate | 24 Mbps - achievable with push-pull drivers and ≤50 Ω output impedance |
| Propagation Delay | 2.4 ns to 8.8 ns - varies by voltage pair and temperature; B→A typically faster than A→B |
| IOFF Leakage | ±12 μA max - limits backflow current when VCC(A) = 0 V or VCC(B) = 0 V |
| ESD Robustness | HBM 8 kV (B port), 2.5 kV (A port); CDM 1.5 kV - meets JEDEC JS-001/JS-002 Class 3B/C3 |
| Operating Temp | –40 °C to +125 °C - fully specified across automotive-grade extended range |
Pinout & Package
VSSOP8 (SOT765-1), XSON8 (SOT833-1), and WLCSP8 (SOT8023-1) packages available; all are 8-terminal devices with identical pin functionality and thermal derating profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Data I/O (A-side) | Bidirectional port referenced to VCC(A); includes internal 10 kΩ pull-up to VCC(A) |
| B1, B2 | Data I/O (B-side) | Bidirectional port referenced to VCC(B); includes internal 10 kΩ pull-up to VCC(B) |
| OE | Output Enable | Active-HIGH signal referenced to VCC(A); drives all I/O into high-impedance state when LOW |
| VCC(A) | Supply A | Power rail for A-side logic, OE input, and internal biasing; must be ≤ VCC(B) |
| VCC(B) | Supply B | Power rail for B-side logic and pull-ups; sets VOH level for B-port outputs |
| GND | Ground | Common reference for all voltages and ESD paths; required for IOFF and latch-up immunity |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external DIR control line; detects data flow direction dynamically via internal one-shot edge detection |
| Dual independent supply rails | VCC(A) and VCC(B) operate independently within their ranges, enabling 1.8 V ↔ 3.3 V and 1.8 V ↔ 5.0 V translation without level-shifter ICs |
| Integrated pull-up resistors | 10 kΩ per I/O pin - reduces external component count for open-drain buses like I²C |
| IOFF partial power-down | Prevents damaging back-current when either supply is off; maintains <±12 μA leakage at 0 V supply |
| High-temp operation | Guaranteed functionality at +125 °C ambient - suitable for under-hood or compact mobile thermal environments |

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 |
|---|---|---|---|
| TXS0102RUGR | TI device uses passive auto-direction sensing; lacks integrated pull-ups; requires external 10 kΩ resistors on both sides | No internal pull-ups → higher BOM cost and layout complexity for I²C; lower static current but same dynamic performance | Choose TXS0102RUGR only if external pull-up values must be tuned below 10 kΩ or if TI supply-chain preference applies |
| NXH0102UK | Nexperia's newer variant with enhanced ESD (12 kV HBM on B port) and tighter tPHL/tPLH matching (0.5 ns skew vs 0.8 ns) | Same pinout and footprint; improved noise immunity in high-interference industrial settings | Select NXH0102UK for new designs targeting >10 kV ESD robustness or sub-nanosecond skew-critical timing |
Compared with TXS0102RUGR and NXH0102UK, the NXS0102 offers lowest component count for I²C due to integrated pull-ups, while NXH0102UK provides superior ESD margin and skew control-making NXS0102 optimal for cost-sensitive consumer designs where 8 kV HBM suffices.

FAQ
Can NXS0102 translate between 1.2 V and 3.3 V domains?
No. VCC(A) minimum is 1.65 V per datasheet Table 6; 1.2 V falls outside the specified operating range. Attempting 1.2 V on A-side risks undefined behavior, increased propagation delay, and potential failure to meet VOL/VOH specs. Use dedicated 1.2 V–compatible translators such as NXH0102UK with extended low-VCC support.
Is external pull-up resistance required when using NXS0102 on an I²C bus?
No external pull-ups are required for basic I²C operation-the device integrates 10 kΩ pull-ups to VCC(A) on A1/A2 and to VCC(B) on B1/B2. However, if faster rise times or stronger drive are needed (e.g., >400 kHz fast-mode Plus), parallel external resistors may be added-but this lowers effective pull-up value and increases VOL.
What happens if VCC(A) exceeds VCC(B) during normal operation?
Per datasheet Section 8 and Table 4 Note [1], VCC(A) must not exceed VCC(B) during active operation. Violation risks forward-biasing internal protection diodes, increasing ICC, degrading VOL/VOH, and potentially causing latch-up. Power-up sequencing is unrestricted, but steady-state VCC(A) > VCC(B) is prohibited.
Does NXS0102 support push-pull drivers on both sides?
Yes-datasheet Section 13.1 explicitly states it "may also be used in applications where push-pull drivers are connected to the ports." Push-pull operation achieves 24 Mbps maximum data rate, though open-drain remains preferred for I²C. B-port tolerates inputs up to 5.5 V regardless of VCC(B), enabling robust interfacing with legacy 5 V logic.
