PCA9506
Overview
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.
- 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 in
