Low-voltage 8-bit I2C-bus and SMBus low power I/O port with interrupt, weak pull-up

General description The PCA9554B and PCA9554C are low-voltage 8-bit General Purpose Input/Output (GPIO) expanders with interrupt for I2C-bus/SMBus applications. The only difference between the PCA9554B and PCA9554C is their I2C fixed address allowing a larger number of the same device on the I2C-

Low-voltage 8-bit I2C-bus and SMBus low power I/O port with interrupt, weak pull-up

The PCA9554B and PCA9554C are low-voltage 8-bit General Purpose Input/Output(GPIO) expanders with interrupt for I²C-bus/SMBus applications. The only differencebetween the PCA9554B and PCA9554C is their I²C fixed address allowing a largernumber of the same device on the I²C-bus with no chance of addr I² C-bus to parallel port expander\nOperating power supply voltage range of 1.65 V to 5.5 V\nLow standby current consumption:1.5 μA (typical at 5 V VDD)\n1.0 μA (typical at 3.3 V VDD)\nSchmitt-trigger action allows slow input transition and better switching noise immunityat the SCL and SDA inputs:Vh;
