Features

Key Features

  • 5-bit 3-to-1 multiplexer, 1-bit latch DIP switch
  • 5-bit external hardware pins
  • Two 6-bit internal non-volatile registers, fully pin-to-pin compatible with PCA9559
  • Selection between the two non-volatile registers
  • Selection between non-volatile registers and external hardware pins
  • I2C/SMBus interface logic
  • Internal pull-up resistors on input pin and control signals
  • Active high write protect on input controls the ability to write to the non-volatile registers
  • 2 address pins, allowing up to 4 devices on the I2C-bus
  • 5 open drain multiplexed outputs
  • Open drain non-multiplexed output
  • Internal 6-bit non-volatile registers programmable and readable via I2C-bus
  • External hardware 5-bit value readable via I2C-bus
  • Multiplexer selection can be overridden by I2C-bus
  • Operating power supply voltage 3.0 V to 3.6 V
  • 5 V and 2.5 V tolerant inputs/outputs
