Description
The CAT9555 is a CMOS device that provides 16
bit parallel input/output port expansion for I2C and SMBus compatible applications.
bit Configuration ports (input or output), Input, Output and Polarity inversion registers, and an I2C/SMBus
compatible serial interface.
Features
- an active low interrupt output which indicates to the system master that an input state has changed. The three address input pins provide the device’s extended addressing capability and allow up to eight devices to share the same bus. The fixed part of the I2C slave address is the same as the CAT9554, allowing up to eight of these devices in any combination to be connected on the same bus. Features.
- 400 kHz I2C Bus Compatible.
- 2.3 V to 5.5 V Operation.
- Low Stand.
