Introduction

AI Translation

The PCA9548A device is equipped with eight bidirectional transfer switches that can be controlled via the I2C bus. The SCL/SDA upstream pair is extended to eight downstream pairs.

Features

AI Translation
  • 8-to-1 bidirectional translating switch, compatible with I2C bus and SMBus
  • Active-low reset input
  • Three hardware address pins allow up to eight PCA9548A devices on the I2C bus
  • Channel selection via I2C bus
  • All switch channels deselected at power-on
  • Low RON switches support voltage level translation between 1.8V, 2.5V, 3.3V, and 5V buses
  • No glitch at power-on
  • Hot-insertion capable
  • Low standby current
  • Operating supply voltage range: 2.3V to 5.5V
  • 5V tolerant inputs
  • Clock frequency: 0kHz to 400kHz
  • Latch-up performance exceeds 100mA per JESD 78 Class II
  • ESD protection exceeds JESD 22 requirements
  • 2000V Human Body Model (A114-A)
  • 200V Machine Model (A115-A)
  • 1000V Charged Device Model (C101)

Applications

AI Translation
  • Servers
  • Routers (telecom switching equipment)
  • Factory automation
  • Products with I2C slave address conflicts (e.g., multiple identical temperature sensors)
