Data Sheet

LSF0108-Q1 Automotive 8-Channel Multi-Voltage Level Translator

1 Features

  • AEC-Q100 qualified with the following results:
    • Device HBM ESD classification level 2000-V
    • Device CDM ESD classification level 1000-V

  • Available in wettable flank VQFN (RKS) package

  • Provides bidirectional voltage translation with no direction pin
  • Supports up to 100 MHz up translation and greater than 100 MHz down translation at ≤ 30-pF capacitive load and up to 40 MHz up or down translation at 50-pF capacitive load
  • Supports hot insertion
  • Allow bidirectional voltage level translation between
    • 0.65 V ↔ 1.8 V, 2.5 V, 3.3 V, 5 V (RKS package only)
    • 0.95 V ↔ 1.8 V, 2.5 V, 3.3 V, 5 V
    • 1.2 V ↔ 1.8 V, 2.5 V, 3.3 V, 5 V

GUID-20221020-SS0I-M2MH-F83D-MV5LWDZRKR48-low.svg Functional Block Diagram

2 Applications

  • GPIO, MDIO, PMBus, SMBus, SDIO, UART, I2C, and other interfaces in telecom infrastructure
  • Infotainment and cluster
  • Body electronics and lighting
  • Hybrid, electric, and powertrain systems
  • Passive safety
  • ADAS

3 Description

  • Supports up to 100 MHz up translation and greater than 100 MHz down translation at ≦ 30 pF capacitive load and up to 40 MHz up and down translation at 50 pF capacitive load:
    • Allows the LSF family to support more consumer or telecom interfaces (MDIO or SDIO)
  • Bidirectional voltage translation without DIR pin:
    • Minimizes system effort to develop voltage translation for bidirectional interface (PMBus, I2C, or SMbus)
  • 5 V tolerance on IO port and 125°C support:
    • With 5 V tolerance and 125°C support, the LSF family is flexible and compliant with TTL levels in industrial and telecom applications
  • Channel specific translation:
    • The LSF family is able to set up different voltage translation levels on each channel
