Description
CAT9554, CAT9554A 8-bit I2C and SMBus I/O Port with Interrupt .
Features
* an active low interrupt output which indicates to the system master that an input state has changed. The device’s extended addressing capability allows up to 8 devices to share the same bus. The CAT9554A is identical to the CAT9554 except the fixed part of the I2C slave address is different. This alApplications
* These I/O expanders provide a simple solution in applications where additional I/Os are needed: sensors, power switches, LEDs, pushbuttons, and fans. The CAT9554/9554A consist of an input port register, an output port register, a configuration register, a polarity inversion register and an I2C/SMBuCAT9554 Distributors
