Nexperia USA Inc. LSF0102DP-Q100H

Overview

LSF0102DP-Q100 from Nexperia is a 2-channel automotive-grade bidirectional multi-voltage level translator supporting open-drain and push-pull interfaces, with up-translation ≤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 camera modules.

For engineers reviewing the LSF0102DP-Q100 datasheet, LSF0102DP-Q100 pinout, LSF0102DP-Q100 application, or LSF0102DP-Q100 equivalent, key selection criteria include bidirectional translation without direction control, flexible per-channel reference voltage pairing (e.g., 1.8 V ↔ 3.3 V), AEC-Q100 Grade 1 qualification, TSSOP8 flow-through pinout, and low R_ON (≤7 Ω at 1.0 V refA) for minimal signal distortion.

Technical Context

The LSF0102DP-Q100 implements passive MOSFET-based translation architecture with dual independent reference inputs (refA, refB), enabling asymmetric voltage translation per channel-e.g., A-side at 1.8 V and B-side at 5.0 V. No direction pin or external biasing is required, and EN (active HIGH) places all I/O pins in high-impedance state when deasserted.

It supports hot insertion and handles capacitive loads up to 50 pF while maintaining sub-1.3 ns propagation delay (t_PHL/t_PLH) across temperature. Translation direction (up/down) is determined automatically by relative voltage levels on An/Bn pins and corresponding refA/refB references, eliminating timing-critical control logic.

FAQ

What is the maximum capacitive load the LSF0102DP-Q100 can drive while maintaining 100 MHz down-translation?

The LSF0102DP-Q100 maintains ≥100 MHz down-translation performance with ≤30 pF total capacitive load (including PCB trace, connector, and device input capacitance). At 50 pF, down-translation drops to ≥50 MHz. This is verified per datasheet Table 8 under CL = 30 pF and CL = 50 pF conditions with V_refA = 1.5 V or 2.3 V.

Can refA and refB be set to the same voltage, and what happens to translation behavior?

Yes, refA and refB may be set to identical voltages (e.g., both at 3.3 V), resulting in unity-gain bidirectional buffering with low R_ON and minimal propagation delay. The device remains fully functional but provides no voltage translation-only signal integrity enhancement and hot-insertion capability.

Does the LSF0102DP-Q100 support open-drain and push-pull outputs simultaneously on the same channel?

No. Each channel (A1/B1 and A2/B2) operates in either open-drain or push-pull mode depending on external pull-up configuration-not internal selection. The device itself has no internal drivers; it passively translates based on external pull-ups and voltage differentials, supporting both topologies transparently via external circuit design.

How does the EN pin affect signal integrity during partial power-down scenarios?

When EN = LOW, all I/O pins (A1, A2, B1, B2) enter high-impedance state with <5 μA leakage, preventing back-driving or contention on powered-down buses. This enables safe partial system shutdown-e.g., disabling camera sensor interface while keeping main SoC active-without signal corruption or shoot-through risk.
