Product details
Overview
NXS0108PW-Q100 from Nexperia is an automotive-qualified 8-bit dual-supply translating transceiver with auto-direction sensing and open-drain outputs, enabling bidirectional level translation between 1.2 V–3.6 V (VCC(A)) and 1.65 V–5.5 V (VCC(B)) domains. It supports up to 110 Mbps push-pull data rates, features IOFF partial power-down protection, and operates across –40 °C to +125 °C for engine control, ADAS sensor interfaces, and infotainment domain controllers.
For engineers reviewing the NXS0108PW-Q100 datasheet, NXS0108PW-Q100 pinout, NXS0108PW-Q100 application, or NXS0108PW-Q100 equivalent, key selection criteria include asymmetric supply tolerance (VCC(A) ≤ VCC(B)), AEC-Q100 Grade 1 qualification, IOFF-enabled hot-swap safety, and TSSOP20 package compatibility with AOI-capable side-wettable flanks.
Technical Context
The device implements auto-direction sensing via internal one-shot circuitry per channel, eliminating external direction-control signals. Its dual-rail architecture isolates A-side (VCC(A)-referenced) and B-side (VCC(B)-referenced) I/Os, with OE referenced solely to VCC(A).
IOFF circuitry actively disables outputs during power-down, blocking backflow current when either supply is at 0 V - critical for mixed-voltage systems undergoing partial shutdown. ESD robustness exceeds 15 kV HBM on the B port and 8 kV IEC61000-4-2 contact discharge, meeting automotive EMC requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V: Enables interface with low-voltage logic (e.g., 1.2 V/1.8 V MCUs) while maintaining signal integrity. |
| VCC(B) Range | 1.65 V to 5.5 V: Supports legacy 3.3 V/5.0 V peripherals, sensors, and CAN/LIN transceivers without level-shifting ICs. |
| Max Data Rate | 110 Mbps (push-pull): Sustains high-speed serial links like SPI clocked at ≥55 MHz with margin for trace skew and jitter. |
| IOFF Leakage | ±1 μA at 25 °C: Prevents >100 μA backfeed current during partial power-down, protecting powered-down subsystems. |
| Propagation Delay | 3.2 ns to 15.8 ns (B→A, VCC(B)=5.0 V, –40 °C to +125 °C): Ensures timing closure in real-time automotive comms with <10 ns channel-to-channel skew. |
| ESD Rating (B port) | 15 kV HBM / 8 kV IEC61000-4-2 contact: Meets ISO 10605 for direct ESD events in vehicle cabin and under-hood environments. |
| Operating Temp | –40 °C to +125 °C: Qualified for powertrain and ADAS modules where junction temperatures exceed 105 °C ambient. |
Pinout & Package
TSSOP20 package (SOT360-1), 4.4 mm body width, with side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A8 | A-side bidirectional I/O | Referenced to VCC(A); accepts inputs up to 5.5 V; drives open-drain outputs compatible with pull-up to VCC(A) or VCC(B). |
| B1–B8 | B-side bidirectional I/O | Referenced to VCC(B); tolerates 0 V to 5.5 V input; enables translation from low-VCC(A) domains to higher-voltage buses. |
| OE | Output enable (active HIGH) | Controlled by VCC(A); asserts high-impedance state on both ports when LOW, enabling bus sharing and power gating. |
| VCC(A) | A-port supply | Powers internal logic and A-side I/O circuitry; must be ≤ VCC(B) per absolute maximum rating. |
| VCC(B) | B-port supply | Powers B-side drivers and level-shift detection; independent regulation allows asynchronous domain operation. |
| GND | Analog/digital ground | Single reference plane for both supplies; requires low-inductance PCB connection to minimize ground bounce in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external DIR control line, reducing PCB routing complexity and enabling true bidirectional SPI/I²C translation without protocol awareness. |
| IOFF partial power-down | Blocks damaging back-current when VCC(A) = 0 V and VCC(B) = 5.5 V, supporting hot-plug diagnostics and fail-safe module isolation. |
| AEC-Q100 Grade 1 | Qualified for automotive applications requiring operation up to +125 °C ambient, including engine control units and radar front-ends. |
| Side-wettable flanks | Enables 100% automated optical inspection of solder fillets on TSSOP20 leads, improving manufacturing yield in Tier-1 SMT lines. |
| Asymmetric voltage tolerance | A-port inputs tolerate up to 5.5 V regardless of VCC(A), allowing safe interfacing with 5 V peripherals even when VCC(A) = 1.2 V. |
Applications
| Engine Control Unit (ECU) Sensor Interface | ADAS Camera Serial Link |

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 |
|---|---|---|---|
| TXS0108E-Q1 | Push-pull outputs only; no open-drain mode; lower max VCC(B) = 5.5 V but no auto-direction sensing - requires external DIR control. | Requires additional GPIO and firmware logic for direction management; unsuitable for true bidirectional protocols like I²C without arbitration. | Select when fixed-direction high-speed links (e.g., SPI) dominate and board space permits extra control routing. |
| NLSX4014MUTAG | 4-bit, not 8-bit; supports 0.9 V–4.5 V VCC(A) and 1.65 V–5.5 V VCC(B); lacks AEC-Q100 qualification and IOFF. | Not qualified for automotive under-hood use; limited channel count increases component count for full bus translation. | Consider only for non-automotive industrial applications needing ultra-low VCC(A) support down to 0.9 V. |
Compared with TXS0108E-Q1 and NLSX4014MUTAG, NXS0108PW-Q100 uniquely combines AEC-Q100 Grade 1, auto-direction sensing, IOFF, and open-drain flexibility in a single 8-bit TSSOP20 package - essential for space-constrained, safety-critical automotive domain controllers.

FAQ
What is the minimum allowed VCC(A)–VCC(B) differential for reliable auto-direction sensing?
VCC(A) must be ≤ VCC(B) per absolute maximum ratings, but reliable auto-direction operation requires VCC(B) ≥ VCC(A) + 0.2 V across temperature. At VCC(A) = 1.2 V, VCC(B) ≥ 1.4 V ensures proper one-shot triggering and avoids metastability in direction detection circuitry.
Can NXS0108PW-Q100 translate from 5.0 V to 1.2 V in both directions?
No. While B-port inputs accept up to 5.5 V regardless of VCC(A), the device only translates *from* the lower-voltage domain *to* the higher-voltage domain (A→B or B→A). Driving 1.2 V logic directly from a 5.0 V source violates VCC(A) ≤ VCC(B) and risks latch-up; it must be used with VCC(A) = 1.2 V and VCC(B) = 5.0 V for A→B translation.
How does IOFF behave when only VCC(B) is powered?
When VCC(A) = 0 V and VCC(B) = 5.5 V, IOFF activates automatically: A-port outputs enter high-impedance state with ±1 μA leakage, preventing current flow from B-port into unpowered A-side circuitry. This protects downstream 1.2 V logic from damage during partial system power-up sequences.
Is the TSSOP20 package (SOT360-1) pin-compatible with the DHVQFN20 variant (NXS0108BQ-Q100)?
No. The TSSOP20 (NXS0108PW-Q100) and DHVQFN20 (NXS0108BQ-Q100) have different pinouts and footprints. TSSOP20 uses standard leaded layout (A1/B1/VCC(A)/VCC(B)/OE/GND sequence), while DHVQFN20 has a rotated, leadless arrangement with GND pad at corner - requiring separate PCB layouts and rework procedures.
