Level Translating Fm+ I²C-Bus Repeater



Key Features

  • 2 channel, bidirectional buffer isolates capacitance and allows 540 pF on either side of the device at 1 MHz and up to 4000 pF at lower speeds
  • Voltage level translation from 0.8 V to 5.5 V and from 2.2 V to 5.5 V
  • Footprint and functional replacement for PCA9517A at Fast-mode speeds
  • Port A operating supply voltage range of 0.8 V to 5.5 V with normal levels
  • Port B operating supply voltage range of 2.2 V to 5.5 V with static offset level
  • 5 V tolerant I2C-bus and enable pins
  • 0 Hz to 1000 kHz clock frequency (the maximum system operating frequency may be less than 1000 kHz because of the delays added by the repeater)
  • Active HIGH repeater enable input referenced to VCC(B)
  • Open-drain input/outputs
  • Latching free operation
  • Supports arbitration and clock stretching across the repeater
  • Accommodates Standard-mode, Fast-mode and Fast-mode Plus I2C-bus devices, SMBus (standard and high power mode), PMBus and multiple controllers
  • Powered-off high-impedance I2C-bus pins
  • ESD protection exceeds 5500 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA

Packages Offered

  • TSSOP8 and HWSON8
