Product details
Overview
LSF0102DC-Q100 from Nexperia is a 2-channel automotive-grade bidirectional multi-voltage level translator supporting open-drain and push-pull interfaces, with up-translation to ≤100 MHz (CL = 30 pF) and down-translation ≥100 MHz (CL = 30 pF), 5 V-tolerant I/O pins, and operation from −40 °C to +125 °C for I²C, SMBus, and GPIO voltage domain bridging in ADAS domain controllers.
For engineers reviewing the LSF0102DC-Q100 datasheet, LSF0102DC-Q100 pinout, LSF0102DC-Q100 application, or LSF0102DC-Q100 equivalent, this page delivers verified translation bandwidths, per-channel reference voltage independence, AEC-Q100 Grade 1 qualification status, and VSSOP8 package routing advantages - all critical for automotive interface coexistence design.
Technical Context
The LSF0102DC-Q100 implements passive FET-based bidirectional translation without direction control logic, using separate refA and refB pins to set independent high-side and low-side voltage domains per channel. Its EN pin enables high-impedance isolation of both A and B ports simultaneously.
It supports mixed-mode translation across five voltage pairings (e.g., 0.95 V ↔ 3.3 V, 1.8 V ↔ 5.0 V), with ON-resistance ranging from 3 Ω to 7 Ω depending on VrefA and load conditions, and maintains signal integrity via low Cio(on) (6–12.5 pF) and fast propagation delays (0.3–1.3 ns typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Translation Speed | Up: ≤100 MHz @ CL = 30 pF; Down: ≥100 MHz @ CL = 30 pF - enables full-speed I²C Fast-mode Plus (1 Mbps) and SMBus 3.0 interoperability. |
| Operating Temp | −40 °C to +125 °C - qualified for engine bay and ADAS ECU placement without derating. |
| Voltage Range | 0.95 V ↔ 5.0 V translation pairs - supports legacy 5 V TTL logic interfacing with modern sub-1 V I/O domains. |
| Input Tolerance | 5 V tolerant I/O pins - allows direct connection to 5 V pull-ups without external clamping diodes. |
| Enable Control | Active-HIGH EN pin - provides system-level power sequencing control and hot-insertion safe isolation. |
| ESD Rating | HBM >2000 V, CDM >1000 V - exceeds AEC-Q100 stress test requirements for automotive assembly environments. |
| Package | VSSOP8 (SOT765-1), 2.3 mm body width - enables high-density routing in space-constrained automotive PCBs. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1), 8 leads, body width 2.3 mm, pin pitch 0.65 mm, flow-through pinout optimized for minimal trace crossovers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common return path for all internal circuitry; must be low-impedance connection to system ground plane. |
| EN | Enable input | Active-HIGH control: drives both channels into high-Z when LOW; synchronizes power-up/down sequencing. |
| refA | Channel A reference voltage | Sets low-side voltage domain for A1/A2; determines threshold and RON for A-side translation. |
| refB | Channel B reference voltage | Sets low-side voltage domain for B1/B2; independently configurable from refA for asymmetric translation. |
| A1, A2 | Data I/O channel A | Bidirectional data pins for first translation channel; internally connected via pass-gate structure. |
| B1, B2 | Data I/O channel B | Bidirectional data pins for second translation channel; electrically isolated from A-side except through FET path. |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Reduces PCB routing complexity and eliminates timing-critical direction-control signals in I²C/SMBus systems. |
| Per-channel ref voltage setting | Enables independent 0.95 V ↔ 3.3 V on Channel 1 and 1.8 V ↔ 5.0 V on Channel 2 within same device. |
| Flow-through pinout | Minimizes layer count and vias: GND–EN–refA–refB on left; A1–B1–A2–B2 on right - ideal for parallel bus layout. |
| Hot insertion support | EN-controlled high-Z state prevents bus contention during live module replacement in telecom or vehicle gateway systems. |
| Low RON (3–7 Ω) | Maintains signal rise/fall times under 30 pF load, preserving timing margins in 100 MHz down-translation paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102QPWRQ1 | Active-push-pull output; requires external pull-ups; higher ICC (15 µA vs. 1 µA typical); no 5 V tolerance on I/O. | Designed for low-power always-on wake-up lines; unsuitable for 5 V-tolerant legacy bus interfacing. | Select when ultra-low standby current is prioritized over 5 V compatibility and passive simplicity. |
| SN74AVC2T244PWR | Unidirectional; dual 2-bit buffers with direction control; 3.6 V max VCC; no refA/refB flexibility. | Requires direction signal routing and cannot translate between arbitrary voltage pairs like 0.95 V ↔ 5.0 V. | Choose only for fixed-direction, single-supply 1.8/3.3 V systems where cost-per-bit is primary constraint. |
Compared with TXS0102QPWRQ1 and SN74AVC2T244PWR, the LSF0102DC-Q100 uniquely combines AEC-Q100 Grade 1 qualification, 5 V I/O tolerance, zero-direction-pin operation, and per-channel reference voltage selection - making it the only option for automotive mixed-voltage I²C/SMBus bridges requiring robustness and routing efficiency.

FAQ
Does LSF0102DC-Q100 require external pull-up resistors?
Yes - external pull-up resistors are required on both A and B sides for open-drain operation. The device itself contains no internal pull-ups; typical values range from 2.2 kΩ to 10 kΩ depending on bus capacitance and speed target. Pull-up voltage must match the respective refA or refB domain.
Can refA and refB be set to the same voltage?
Yes - refA and refB may be tied together to the same voltage source, enabling symmetric translation (e.g., 1.8 V ↔ 3.3 V on both channels). This configuration preserves full bandwidth and simplifies layout when identical voltage domains are bridged across both channels.
What happens to A1/A2 and B1/B2 when EN = LOW?
When EN = LOW, all four I/O pins (A1, A2, B1, B2) enter high-impedance state with Cio(off) ≤ 6.0 pF, effectively disconnecting both sides of both channels. This prevents bus contention during power sequencing or fault isolation in automotive gateways.
Is LSF0102DC-Q100 compatible with I²C Fast-mode Plus (1 Mbps)?
Yes - with CL ≤ 30 pF and appropriate pull-up sizing, the device supports ≥100 MHz down-translation and ≤100 MHz up-translation, exceeding the 1 Mbps (1 MHz) requirement of I²C Fast-mode Plus. Verified performance includes tPHL/tPLH < 1.3 ns typical at 30 pF load.
