Product Overview

PCA9548AD,118 is an 8-channel I2C-bus switch with reset. This is an octal bidirectional translating switch controlled via the I2C-bus. The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register. An active LOW reset input allows the PCA9548A to recover from a situation where one of the downstream I2C-buses is stuck in a LOW state. Pulling the (active low) RESET pin LOW resets the I2C-bus state machine and causes all the channels to be deselected as does the internal Power-on reset function.
  • Supply voltage range from 2.3 to 5.5V
  • I2C-bus interface logic; compatible with SMBus standards
  • Active LOW RESET input, 3 address pins allowing up to 8 devices on the I2C-bus
  • Channel selection via I2C-bus, one channel at a time
  • Power-up with all channels deselected except Channel 0 which is connected
  • Low Ron multiplexers, no glitch on power-up, supports hot insertion, low standby current
  • 6V tolerant inputs and 0Hz to 400kHz clock frequency
  • Allows voltage level translation between 1.8V, 2.5V, 3.3V and 5V buses
  • ESD protection exceeds 2000V HBM per JESD22-A114 and 1000V CDM per JESD22-C101
  • 24 pin SO package, ambient temperature range from -40 to 85°C
