PCA9505 - 40-bit I2C-bus I/O port

The PCA9505/PCA9506 provide 40-bit parallel input/output (I/O) port expansion for I2Cbus 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 .

PCA9505 Features

* 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 kΩ internal pull-up resistors on all the I/Os
