16-bit I2C-bus and SMBus I/O port with interrupt

The PCA9555 is a 24-pin CMOS device that provides 16 bits of General Purpose parallel Input/Output (GPIO) expansion for I²C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements include higher drive capability, 5 V I/O tolerance, • Operating power supply voltage range of 2.3 V to 5.5 V\n• 5 V tolerant I/Os\n• Polarity Inversion register\n• Active LOW interrupt output\n• Low standby current\n• Noise filter on SCL/SDA inputs\n• No glitch on power-up\n• Internal power-on reset\n• 16 I/O pins which default to 16 inputs\n• 0 Hz t;
