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

The PCA9554 and PCA9554A are 16-pin CMOS devices that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and were developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements include higher drive capability, 5 V I/ • 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• 8 I/O pins which default to 8 inputs\n• 0 Hz to ;
