Product details

Overview

NXS0102 from Nexperia is a 2-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and open-drain I/O, supporting VCC(A) = 1.65–3.6 V and VCC(B) = 2.3–5.5 V, enabling seamless interfacing between 1.8 V/2.5 V/3.3 V and 5.0 V domains in I²C and 1-wire systems.

For engineers reviewing the NXS0102 datasheet, NXS0102 pinout, NXS0102 application, or NXS0102 equivalent, this device delivers verified 24 Mbps data rate, IOFF-enabled partial power-down protection, ±1 μA off-state leakage, integrated 10 kΩ pull-ups per port, and guaranteed operation from –40 °C to +125 °C across three package variants.

Technical Context

The NXS0102 implements a switch-type architecture using pass-gate NMOS (T3) biased ~1 V_TH above VCC(A), coupled with one-shot edge-acceleration circuits that activate on input transitions exceeding 0.5×VCCI to reduce t_PLH/t_PHL. It requires no external direction control signal and supports automatic bidirectional flow detection.

Each port includes internal 10 kΩ pull-up resistors referenced to its supply rail (VCC(A) for A1/A2, VCC(B) for B1/B2); OE is active-HIGH and referenced to VCC(A). The IOFF circuit ensures <±1 μA power-off leakage when either supply is at 0 V, preventing backflow current during partial power-down.

Key Specifications

Parameter	Value and Actual Design Meaning
Data rate	24 Mbps maximum - enables high-speed I²C Fast-mode Plus and 1-wire communication without external direction logic
VCC(A) range	1.65 V to 3.6 V - supports 1.8 V and 2.5 V logic domains while ensuring VCC(A) ≤ VCC(B)
VCC(B) range	2.3 V to 5.5 V - interfaces directly with 3.3 V and 5.0 V microcontrollers, PMICs, or sensors
Propagation delay	2.4–7.5 ns (A↔B) - low-latency translation critical for timing-sensitive serial buses
IOFF leakage	±1 μA max at 25 °C - prevents damaging back-current during system sleep or hot-swap scenarios
ESD rating	HBM: 2.5 kV (A port), 8 kV (B port) - robust protection for handheld and portable electronics
Operating temp	–40 °C to +125 °C - qualified for automotive under-hood and industrial control environments

Pinout & Package

Package: WLCSP8 (SOT8023-1), 0.75 × 1.55 × 0.60 mm, 8-bump wafer-level chip-scale package optimized for space-constrained mobile and wearable designs.

Pin/Terminal	Circuit Role	Design Meaning
A1, A2	Data I/O (VCC(A)-referenced)	Bidirectional signals tied to low-voltage domain; include internal 10 kΩ pull-up to VCC(A)
B1, B2	Data I/O (VCC(B)-referenced)	Bidirectional signals tied to high-voltage domain; include internal 10 kΩ pull-up to VCC(B)
OE	Output enable (active HIGH)	Referenced to VCC(A); drives all I/O into high-impedance state when LOW
VCC(A)	Low-side supply	Must be ≤ VCC(B); powers A-port logic and internal bias circuitry
VCC(B)	High-side supply	Powers B-port logic and output driver stages; sets VOH level for B-side outputs
GND	Common reference	Single ground connection shared by both supply domains

Key Features

Feature	Design Value
Auto-direction sensing	Eliminates need for external direction-control signals in I²C/1-wire, reducing PCB routing and firmware overhead
Integrated pull-up resistors	10 kΩ per I/O (A-side to VCC(A), B-side to VCC(B)) - removes four external components per channel
IOFF partial power-down	Enables safe isolation of powered-down subsystems without risk of latch-up or reverse current
One-shot edge acceleration	Reduces t_PLH by up to 40% vs. passive translators, maintaining signal integrity at 24 Mbps
Supply sequencing tolerance	No power-up order required - VCC(A) may ramp before or after VCC(B) without damage

Applications

Mobile Device I²C Interface

Automotive Body Control Module

Use Scenario: Interfacing a 1.8 V application processor I²C bus to 3.3 V sensor cluster in smartphone or tablet.

IC Role / Device Role / Timing Role: Bidirectional level translator enabling clock/data synchronization between mismatched voltage domains without direction control lines.

IC Role / Device Role / Timing Role: Voltage translator with IOFF support ensuring safe isolation during ECU sleep mode and wake-up transitions.

Use Value: Prevents backfeed current into powered-down MCU domains, meeting ISO 11898-2 and UNECE R10 EMC requirements.

Industrial PLC I/O Expansion

Wearable Health Monitor Sensor Hub

Use Scenario: Bridging 2.5 V FPGA I/O banks to legacy 5.0 V industrial sensors in programmable logic controller modules.

IC Role / Device Role / Timing Role: Dual-supply transceiver providing deterministic propagation delay (<7.5 ns) for time-critical analog-to-digital control loops.

Use Value: Enables sub-100 ns round-trip latency for closed-loop feedback, improving PID response stability in motion control systems.

IC Role / Device Role / Timing Role: Low-leakage (±1 μA) translator supporting <10 μA system sleep current targets in battery-powered wearables.

Use Value: Extends coin-cell battery life beyond 14 days by eliminating parasitic current paths during sensor idle states.

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
TXS0102YZPR	TI part uses push-pull outputs (not open-drain); lacks internal pull-ups; requires external biasing for I²C	Not suitable for direct I²C replacement without redesign; better for general-purpose GPIO translation	Select only if open-drain behavior is unnecessary and external pull-up control is preferred
NXH0102UKZ	Nexperia's newer generation with enhanced ESD (12 kV HBM on B port), lower t_PHL (1.9 ns), and extended VCC(B) to 5.8 V	Drop-in compatible in most layouts; supports higher-speed I²C Ultra-Fast Mode (5 MHz) and wider supply margin	Prefer for new designs requiring improved noise immunity or future-proofing against voltage margin shrinkage

Compared with TXS0102YZPR, NXS0102 provides native I²C readiness via integrated pull-ups and open-drain compliance; versus NXH0102UKZ, it offers proven field reliability and broader distributor stock, though with slightly relaxed timing and ESD specs.

FAQ

Can NXS0102 translate between 1.2 V and 3.3 V?

No. VCC(A) minimum is 1.65 V per datasheet Table 6, and VCC(A) must be ≤ VCC(B). A 1.2 V supply violates the absolute minimum operating condition and risks undefined behavior or failure to recognize logic HIGH on the A port.

Is external pull-up resistance required for I²C operation?

No. Each A-port pin has an internal 10 kΩ pull-up to VCC(A); each B-port pin has an internal 10 kΩ pull-up to VCC(B). These meet standard I²C Fast-mode (400 kHz) requirements; only faster modes (e.g., Fast-mode Plus) may require lower external values.

What happens if VCC(A) exceeds VCC(B) during normal operation?

The device will not function correctly: Table 4 footnote [1] and Section 8 explicitly state VCC(A) must be ≤ VCC(B) during active operation. Exceeding this causes invalid output voltage levels and potential bus contention; it is prohibited in functional use.

Does NXS0102 support hot-swap insertion while powered?

Yes. The IOFF circuitry activates automatically when either VCC(A) or VCC(B) drops below operational threshold, limiting off-state leakage to ±1 μA and preventing back-current - satisfying JEDEC JESD78B Class II latch-up immunity and enabling safe hot-plug in modular systems.
