LSF0108-Q1 (ACTIVE)

Automotive 8-Channel Bidirectional Multi-Voltage-Level Translator

 

Description

  • Supports up to 100 MHz up translation and greater than 100 MHz down translation at <= 30 pF cap load and up to 40 MHz up/down translation at 50 pF cap 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.
