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 恩XP 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 ;
