Fonctionnalités et applications

The PCA9506BS,118 is a 40-bit parallel input/output (I/O) port expansion for I2C-bus applications organized in 5 banks of 8 I/Os. At 5 V supply voltage, the outputs are capable of sourcing 10 mA and sinking 15 mA with a total package load of 600 mA to allow direct driving of 40 LEDs. Any of the 40 I/O ports can be configured as an input or output. Output ports are totem-pole and their logic state changes at the Acknowledge (bank change)

The PCA9505 is identical to the PCA9506 except that it includes 100 kO internal pull-up resistors on all the I/Os. The PCA9506 does not include the internal pull-ups on the I/Os to reduce power consumption when used as outputs or when the input is driven by a push-pull driver


  • Standard mode (100 kHz) and Fast mode (400 kHz) compatible I2C-bus serial interface
  • 2.3 V to 5.5 V operation with 5.5 V tolerant I/Os
  • 40 configurable I/O pins that default to inputs at power-up
  • PCA9505 includes 100 kO internal pull-up resistors on all the I/Os
  • Active LOW reset (RESET) input pin resets device to power-up default state
  • 3 programmable address pins allowing 8 devices on the same bus
  • Designed for live insertion
    • Minimize line disturbance (IOFF and power-up 3-state)
    • Signal transient rejection (50 ns noise filter and robust I2C-bus state machine)
  • Low standby current
  • -40 °C to +85 °C operation
  • ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per
  • JESD22-A115, and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78, which exceeds 100 mA
  • Offered in TSSOP56 (PCA9505, PCA9506) and HVQFN56 (PCA9506) packages
