General description
The PCA9505/PCA9506 provide 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 kΩ internal pull-up resistors on all the I/Os.
