LSF0102 (ACTIVE) Dual Bidirectional Multi-Voltage Level Translator

 

Description

The LSF family of devices supports bidirectional voltage translation without the need for DIR pin which minimizes system effort (for PMBus, I2C, SMBus, etc.). The LSF family of devices supports up to 100-MHz up translation and greater than 100-MHz down translation at ≤ 30pF cap load and up to 40-MHz up/down translation at 50pF cap load which allows the LSF family to support more consumer or telecom interfaces (MDIO or SDIO).

LSF family supports 5-V tolerance on I/O port which makes it compatible with TTL levels in industrial and telecom applications. The LSF family is able to set up different voltage translation levels on each channel which makes it very flexible.

Features

  • Provides bidirectional voltage translation with no direction pin
  • Supports up to 100-MHz up translation and greater than 100-MHz down translation at
    ≤ 30pF cap load and up To 40-MHz up/down translation at 50pF cap load
  • Allows bidirectional voltage-level translation between
    • 0.95 V ↔ 1.8/2.5/3.3/5 V
    • 1.2 V ↔ 1.8/2.5/3.3/5 V
    • 1.8 V ↔ 2.5/3.3/5 V
    • 2.5 V ↔ 3.3/5 V
    • 3.3 V ↔ 5 V
  • Low standby current
  • 5-V tolerance I/O port to support TTL
  • Low RON provides less signal distortion
  • High-impedance I/O pins for EN = Low
  • Flow-through pinout for easy PCB trace routing
  • Latch-up performance >100 mA per JESD 17
  • –40°C to 125°C Operating temperature range
