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-bus with no chance of address conflict. NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in ACPI power switches, sensors, push buttons, LEDs, fan control, etc.

Features and benefits

â– I2C-bus to parallel port expander
