Product details
Overview
NXS0108PWJ from Nexperia is an 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 voltage nodes including 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V, features IOFF partial power-down protection, and operates across –40 °C to +125 °C for use in mobile SoC interconnects.
For engineers reviewing the NXS0108PWJ datasheet, NXS0108PWJ pinout, NXS0108PWJ application, or NXS0108PWJ equivalent, key selection criteria include its auto-sensing direction control, 110 Mbps push-pull data rate at 3.3 V/5.0 V, ±1 μA off-state leakage, 1 ns output skew, and TSSOP20 package compatibility with high-density PCB layouts.
Technical Context
The NXS0108PWJ implements dual-rail I/O architecture with independent A- and B-side supply references (VCC(A) and VCC(B)), where A-port pins (A1–A8, OE) are referenced to VCC(A) and B-port pins (B1–B8) to VCC(B). Its auto-direction sensing eliminates external control logic by detecting signal flow direction via internal one-shot circuitry per channel.
It uses open-drain outputs on both sides with integrated pull-up resistors (Rpu) and supports true 3-state operation via active-HIGH OE. The IOFF circuit enforces <±1 μA power-off leakage when either supply is at 0 V, preventing backflow current during partial power-down sequences in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-side I/O and OE; enables interface with ultra-low-voltage cores (e.g., 1.2 V ARM Cortex-M cores) |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/O; supports legacy 5 V peripherals and modern 3.3 V/2.5 V buses |
| Max Data Rate | 110 Mbps (push-pull, VCC(A)=3.3 V/VCC(B)=5.0 V) - sufficient for high-speed I²C, SPI, and GPIO expansion in smartphones |
| IOFF Leakage | ±1 μA at 0 V supply - ensures safe hot-plug and rail sequencing in battery-backed systems without external isolation |
| Propagation Delay | 3.2 ns to 11.5 ns (B→A, VCC(B)=5.0 V, –40 °C to +125 °C) - guarantees timing closure in sub-ns-critical inter-die links |
| ESD Robustness | B port: 15 kV HBM, 8 kV IEC61000-4-2 contact - protects against ESD events during handheld device assembly and field operation |
| Operating Temp | –40 °C to +125 °C - qualified for automotive infotainment and industrial edge compute applications requiring extended thermal range |
Pinout & Package
TSSOP20 (SOT360-1) package: 20-pin plastic thin shrink small outline, 4.4 mm body width, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A8 | A-side bidirectional I/O | Referenced to VCC(A); auto-sensed direction; tolerate up to 5.5 V input regardless of VCC(A) |
| B1–B8 | B-side bidirectional I/O | Referenced to VCC(B); open-drain outputs; support external pull-ups to VCC(B) or other rails |
| OE | Output enable (active HIGH) | Referenced to VCC(A); drives all A/B ports into high-impedance when LOW; enables system-level bus arbitration |
| VCC(A) | A-port supply | Powers A-side logic and OE input; must be ≤ VCC(B) per functional table constraint |
| VCC(B) | B-port supply | Powers B-side logic and output drivers; sets VOH threshold (0.67×VCC(B)) and VOL ceiling (0.55 V) |
| GND | Digital ground reference | Common return for both supplies; required for valid voltage referencing and ESD path integrity |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals in bidirectional buses like I²C or shared memory interfaces |
| Dual-supply translation | Enables seamless interconnection between 1.2 V FPGA I/O banks and 5 V sensor hubs without discrete level shifters |
| IOFF partial power-down | Prevents back-current when VCC(A) or VCC(B) is unpowered-critical for USB-C PD negotiation and battery-isolated subsystems |
| Low propagation skew | ≤1.1 ns max skew between any two channels ensures deterministic timing in parallel data paths (e.g., address/data multiplexing) |
| High ESD immunity (B port) | 15 kV HBM and 8 kV IEC61000-4-2 contact rating allows direct integration in front-panel or connector-facing circuits |
Applications
| Smartphone Application | Automotive Infotainment |

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 | TI part uses push-pull outputs (not open-drain); lacks IOFF; max VCC(B)=5.5 V but no 1.2 V VCC(A) support | Requires external pull-ups for open-drain protocols; unsuitable for partial power-down scenarios | Select only if push-pull drive and absence of IOFF are acceptable in your rail sequencing scheme |
| NLSX4014MUTAG | ON Semiconductor part offers 10-bit width and 1.65 V–5.5 V dual-rail range but no auto-direction sensing-requires DIR pin control | Needs additional GPIO for direction control; higher pin count (24-pin UDFN) increases layout complexity | Choose when fixed-direction data paths dominate and board space permits extra control routing |
Compared with TXS0108E and NLSX4014MUTAG, the NXS0108PWJ uniquely combines auto-direction sensing, true open-drain outputs, and robust IOFF protection-making it optimal for space-constrained, multi-rail embedded systems requiring zero-external-control bidirectional translation.

FAQ
What is the minimum allowed VCC(A)–VCC(B) differential for reliable operation?
VCC(A) must be ≤ VCC(B) per the functional table; no minimum differential is specified, but VCC(A) ≥ 1.2 V and VCC(B) ≥ 1.65 V must both be satisfied. Operation is guaranteed down to VCC(A) = 1.2 V and VCC(B) = 1.65 V simultaneously, enabling 1.2 V ↔ 1.8 V translation with 0.6 V headroom.
Can NXS0108PWJ drive standard 5 V TTL inputs directly?
No. Its B-side outputs are open-drain and require external pull-up to VCC(B) or another rail. To drive 5 V TTL, connect B-port outputs to a 5 V pull-up; VOH will then be ~5 V, satisfying TTL VIH (≥2.0 V), but VOL remains ≤0.55 V, meeting TTL VIL (≤0.8 V).
Is the TSSOP20 package (PW) pin-compatible with the DHVQFN20 (BQ) variant?
No. Pin numbering and physical layout differ significantly: PW uses linear 20-pin TSSOP with GND at pin 11 and OE at pin 10; BQ uses 20-terminal QFN with GND pad centered and OE at terminal 11. Footprints and routing are not interchangeable without PCB redesign.
Does the auto-direction sensing function work with slow-rising or slew-rate-limited signals?
Yes. The internal one-shot circuitry triggers on input transition edges, not absolute voltage thresholds. With recommended Δt/ΔV ≤ 10 ns/V, it reliably detects direction even on signals with rise/fall times up to 100 ns (e.g., 1 V/ns edge), covering typical I²C and SMBus waveforms.
