General description
The PCA9506 provides 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 25 mA with a total package load of 800 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).
com
The device can be configured to have each input port to be masked in order to prevent it from generating interrupts...
