Product details
Overview
LSF0204GU12-Q100 from Nexperia is a 4-channel automotive-grade bidirectional multi-voltage level translator supporting open-drain and push-pull interfaces, with ≤100 MHz up-translation and ≥100 MHz down-translation at ≤30 pF load, 5 V-tolerant I/O pins, and no direction pin required. It enables voltage translation between 0.8 V–5.0 V pairs (e.g., 1.2 V ↔ 3.3 V) in automotive infotainment and ADAS domain controllers.
For engineers reviewing the LSF0204GU12-Q100 datasheet, LSF0204GU12-Q100 pinout, LSF0204GU12-Q100 application, or LSF0204GU12-Q100 equivalent, key selection criteria include channel-wise independent reference voltage assignment (refA/refB), AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), low RON (≤7 Ω), and XQFN12 package thermal performance for space-constrained PCB layouts.
Technical Context
The LSF0204GU12-Q100 uses passive MOSFET-based translation architecture with internal 400 kΩ pull-up on EN referenced to refA, enabling automatic bidirectional signal flow without control logic overhead. Its dual-reference design (refA for EN and side-A, refB for side-B) allows independent voltage domain setup per channel pair.
Dynamic operation supports hot insertion and handles capacitive loads up to 50 pF with propagation delays as low as 0.2 ns (tPLH, translating up at 15 pF) and fMAX of 100 MHz under 50 pF loading-verified across −40 °C to +125 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent bidirectional data paths (A1–A4 / B1–B4) |
| Translation Direction | Fully bidirectional with no direction pin; auto-sensing based on voltage differential |
| Max Frequency | 100 MHz up-translation (1.2 V → 3.3 V, CL = 50 pF); ≥100 MHz down-translation (3.3 V → 1.2 V, CL = 30 pF) |
| Reference Voltages | refA (0.8–5.0 V) sets EN threshold and side-A logic levels; refB (0.8–5.0 V) sets side-B levels |
| ON Resistance | ≤7 Ω typical (1.0 V → 3.3 V, IO = 10 mA), minimizing signal distortion and voltage drop |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive board-level ESD robustness requirements |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and cockpit modules |
Pinout & Package
XQFN12 (SOT1174-1) package: 1.70 × 2.00 × 0.50 mm body, 12-terminal no-lead quad flat design optimized for thermal dissipation and high-density routing in automotive ECUs.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | refA | Reference voltage for EN input and side-A I/O; defines logic thresholds for A-side signals |
| 2–5 | A1–A4 | Bidirectional data terminals for side-A (e.g., 1.2 V/1.8 V domain) |
| 6 | GND | Ground reference (0 V) for all internal circuitry and signal return path |
| 7–10 | B4–B1 | Bidirectional data terminals for side-B (e.g., 3.3 V/5.0 V domain); pin order reversed vs TSSOP |
| 11 | refB | Reference voltage for side-B I/O; independent of refA to enable asymmetric translation |
| 12 | EN | Active-HIGH enable input referenced to refA; disables all channels when LOW (high-impedance state) |
Key Features
| Feature | Design Value |
|---|---|
| No direction pin required | Reduces MCU GPIO count and eliminates timing-critical direction-control firmware overhead |
| Per-channel voltage flexibility | Independent refA/refB assignment enables mixed-domain interfaces (e.g., 1.2 V SoC ↔ 5 V sensor bus) |
| Low RON & signal integrity | ≤7 Ω ON resistance preserves rise/fall times and minimizes duty-cycle distortion in clock/data lines |
| Hot-insertion support | Prevents bus contention during live module replacement in modular vehicle architectures |
| 5 V-tolerant I/O | Allows direct connection to legacy 5 V peripherals without external clamping or level-shifting components |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E-Q1 | 4-channel, push-pull only; requires external pull-ups for open-drain mode; higher ICC (15 µA vs 1 µA) | Lacks native open-drain support; less suitable for I²C/SMBus without added components | Prefer LSF0204GU12-Q100 when open-drain compatibility or ultra-low standby current is required. |
| SN74AVC4T245-Q1 | Direction-pin controlled; unidirectional per channel unless externally wired; higher RON (10 Ω typical) | Requires MCU GPIO for direction control; adds firmware complexity and timing risk | Choose LSF0204GU12-Q100 for simplified layout and deterministic bidirectional behavior without software intervention. |
Compared with TXS0104E-Q1 and SN74AVC4T245-Q1, the LSF0204GU12-Q100 delivers true pinless bidirectionality, lower RON, and native open-drain support-critical for automotive I²C, SMBus, and MDIO where bus arbitration and low-power idle states are mandatory.

FAQ
What is the maximum capacitive load the LSF0204GU12-Q100 can drive while maintaining 100 MHz operation?
The device sustains 100 MHz up-translation (e.g., 1.2 V → 3.3 V) with ≤30 pF total load capacitance, including PCB trace, probe, and device pin capacitance. At 50 pF, maximum frequency drops to 80 MHz per dynamic characterization data-designers must verify layout parasitics against Table 7 limits.
Can refA and refB be set to the same voltage, and what effect does that have?
Yes, refA and refB may be tied to identical voltages (e.g., both at 3.3 V), resulting in unity-gain buffer operation with bidirectional pass-through. This configuration retains all benefits-including hot insertion, low RON, and EN-controlled disable-while eliminating voltage translation.
How does the EN pin behave when refA is below 1.0 V?
EN is referenced to refA; its valid HIGH threshold is 0.7×refA (min) per Table 5. If refA = 0.8 V, EN requires ≥0.56 V to activate. Below refA = 1.0 V, VIH/VIL values scale linearly-ensuring reliable enable/disable across the full 0.8–5.0 V refA range.
Is the XQFN12 package lead-free and RoHS-compliant?
Yes, the SOT1174-1 (XQFN12) package is lead-free and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with homogeneous material declarations available through Nexperia's product compliance portal.
