8.1 Application Information

Applications of the TCAL6408 use this device connected as a responder to an I2C controller (processor), and the I2C bus may contain any number of other responder devices. The TCAL6408 is in a remote location from the controller, placed close to the GPIOs to which the controller needs to monitor or control.

A typical application of the TCAL6408 operates with a lower voltage on the controller side (VCCI), and a higher voltage on the P-port side (VCCP). The P-ports can be configured as outputs connected to inputs of devices such as enable, reset, power select, the gate of a switch, and LEDs. The P-ports can also be configured as inputs to receive data from interrupts, alarms, status outputs, or push buttons.
