LSF0108

8-bit bidirectional multi-voltage level translator; open-drain; push-pull

The LSF0108 is an 8 Channel bidirectional multi-voltage level translator for open-drain and push-pull applications. It supports up to 100 MHz up translation and ≥ 100 MHz down translation at ≤ 30 pF capacitive load. There is no need for a direction pin which minimizes system effort. The LSF0108 supports 5 V tolerant I/O pins for compatibility with TTL levels in a variety of applications. The ability to set up different voltage translation levels on each channel makes the device very flexible and suitable for a lot of different applications.

Features and benefits

  • Bidirectional voltage translation with no direction pin

  • Up translation

    • ≤ 100 MHz; CL = 30 pF

    • ≤ 50 MHz; CL = 50 pF

  • Down translation

    • ≥ 100 MHz; CL = 30 pF

    • ≥ 50 MHz; CL = 50 pF

  • Hot insertion

  • Bidirectional voltage level translation between:

    • 0.95 V and 1.8 V, 2.5 V, 3.3 V and 5.0 V

    • 1.2 V and 1.8 V, 2.5 V, 3.3 V and 5.0 V

    • 1.8 V and 2.5 V, 3.3 V and 5.0 V

    • 2.5 V and 3.3 V and 5.0 V

    • 3.3 V and 5.0 V

  • Low standby current

  • 5 V tolerant I/O pins 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 exceeds 100 mA per JESD78 class II level A

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Specified from -40 °C to +125 °C

Applications

  • GPIO, MDIO, PMBus, SMBus, SDIO, UART, I2C, and other interfaces in Telecom infrastructure

  • Industrial

  • Personal computing
