Product details
Overview
NXS0104UMAZ from Nexperia is a 4-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 features 12-bump WLCSP packaging, IOFF partial power-down protection, ±1 μA off-state leakage, and 24 Mbps max data rate. It is used in smartphone I²C bus interfacing between 1.8 V sensor subsystems and 3.3 V application processors.
For engineers reviewing the NXS0104UMAZ datasheet, NXS0104UMAZ pinout, NXS0104UMAZ application, or NXS0104UMAZ equivalent, this page delivers verified functional architecture, WLCSP bump mapping, temperature-rated dynamic timing (tPHL ≤ 3.9 ns at VCC(A)=3.3 V/VCC(B)=5.0 V), IOFF-enabled power sequencing behavior, and validated alternative options for voltage translation in space-constrained mobile designs.
Technical Context
The NXS0104UMAZ implements a switch-type voltage translator architecture using pass-gate NMOS transistors biased at ~VTH above the lower supply rail, eliminating external direction control. Its auto-sensing one-shot edge accelerator activates on input transitions ≥0.5×VCCI to drive outputs via PMOS bypass paths, reducing tTHL/tTLH and enabling 24 Mbps operation with internal 10 kΩ pull-ups on both A and B ports.
It supports true partial power-down: when either VCC(A) or VCC(B) is at GND, IOFF circuitry disables all I/Os, limiting backflow current to ±2 μA across -40 °C to +125 °C. OE is active-HIGH referenced to VCC(A), and the device requires no power-up sequencing-VCC(A) may ramp before VCC(B) without damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - sets low-voltage domain; must be ≤ VCC(B) for safe operation |
| VCC(B) Range | 2.3 V to 5.5 V - defines high-voltage domain; enables 1.8 V ↔ 5.0 V translation |
| Max Data Rate | 24 Mbps - achievable with push-pull drivers and ≤50 Ω source impedance |
| IOFF Leakage | ±2 μA max - prevents damaging backflow during asymmetric power-down |
| Propagation Delay | tPHL ≤ 3.9 ns (A→B, VCC(A)=3.3 V/VCC(B)=5.0 V) - ensures timing closure in high-speed I²C variants |
| Operating Temp | -40 °C to +125 °C - qualified for automotive infotainment and industrial handheld environments |
| ESD Robustness | B-port: ±8 kV contact (IEC61000-4-2), ±15 kV HBM - protects against handling and system-level ESD events |
Pinout & Package
Package: WLCSP12 (SOT8019-1), 1.36 mm × 1.86 mm × 0.60 mm, 12-bump configuration with die-side down mounting and no leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | Data I/O (VCC(A)-referenced) | Bidirectional signals tied to low-voltage domain; include internal 10 kΩ pull-up to VCC(A) |
| B1–B4 | Data I/O (VCC(B)-referenced) | Bidirectional signals tied to high-voltage domain; include internal 10 kΩ pull-up to VCC(B) |
| VCC(A) | Low-side supply | Power rail for A-port logic and OE input; must be ≤ VCC(B) during operation |
| VCC(B) | High-side supply | Power rail for B-port logic; enables 5.0 V interface compatibility |
| GND | Ground reference | Common 0 V reference for both domains; required for IOFF and ESD clamp operation |
| OE | Output enable (active HIGH) | Controls global I/O state; LOW forces all ports into high-Z; referenced to VCC(A) |
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-supports mixed-voltage SoC subsystems without shared regulators |
| IOFF partial power-down | Prevents back-current when either supply is off; critical for battery-powered devices entering sleep states |
| Integrated 10 kΩ pull-ups | Reduces BOM count for open-drain buses like I²C; disabled automatically when OE = LOW |
| WLCSP12 footprint | 1.36 mm × 1.86 mm area saves >60% board space vs. TSSOP14; optimized for thin mobile PCBs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXH0104BQ | DHVQFN14 package (2.5 × 3 × 0.85 mm); higher thermal dissipation (500 mW Ptot); same electrical specs | Better suited for high-temperature industrial environments where WLCSP thermal resistance is limiting | Select when board-level thermal management exceeds 116 °C ambient or reflow profile requires leaded package reliability |
| NXB0104PW | TSSOP14 package; push-pull output architecture (no auto-direction sensing); requires external DIR control | Optimized for unidirectional or fixed-direction translation; lacks IOFF and open-drain auto-sense capability | Choose only if direction is static and board space allows larger footprint; not suitable for I²C or 1-Wire |
Compared with NXH0104BQ and NXB0104PW, the NXS0104UMAZ uniquely combines ultra-compact WLCSP packaging, auto-direction sensing, and IOFF protection-making it the sole option for space-constrained, bidirectional, battery-sensitive mobile applications requiring zero-direction-control overhead.

FAQ
Can NXS0104UMAZ translate between 1.8 V and 5.0 V without external components?
Yes. With VCC(A) = 1.8 V and VCC(B) = 5.0 V, the NXS0104UMAZ performs bidirectional level translation using its internal pass-gate architecture and auto-direction sensing. No external DIR line, pull-ups, or biasing resistors are needed-the device includes 10 kΩ internal pull-ups on both sides and meets I²C timing requirements up to 1 MHz Fast-mode Plus.
What happens if VCC(A) exceeds VCC(B) during normal operation?
The datasheet explicitly prohibits VCC(A) > VCC(B) during active operation, as it risks forward-biasing internal protection diodes and causing excessive current. However, during power-up sequencing, transient VCC(A) ≥ VCC(B) is allowed and non-damaging-the device includes built-in safeguards that prevent latch-up or permanent degradation under such conditions.
How does the one-shot edge accelerator affect signal integrity with heavy capacitive loads?
The one-shot pulse duration is fixed (~50 ns). If total load capacitance (PCB trace + connector + receiver input) exceeds ~30 pF, the output may fail to reach VOH within that window, causing slow rise times or incomplete logic transitions. Layout best practices mandate short traces (<2 cm), minimal stubs, and avoidance of connectors with >5 pF capacitance per pin.
Is OE referenced to VCC(A) or VCC(B), and what is its voltage threshold?
OE is strictly referenced to VCC(A). Its VIH threshold is 0.65×VCC(A) minimum, and VIL is 0.35×VCC(A) maximum-ensuring reliable activation across the full 1.65 V–3.6 V VCC(A) range. Driving OE from a 3.3 V GPIO without level shifting is unsafe if VCC(A) < 2.5 V, as VIH may not be met.
