The interrupt has an open-drain output, which means you need a pull-up on your microcontroller to detect when the PCF8574 drives it LOW. When setting a pin HIGH, it acts as both output AND input. The pin internally uses a weak current-source pull-up to latch output HIGH. When driven...

The PCA9538 open-drain interrupt output (INT) is activated when any input state differs from its corresponding Input Port register state and is used to indicate to the system controller that an input state has changed. The power-on reset sets the registers to their default values and initialize...
The PI4IOE5V9538 open-drain interrupt output ( INT ) is activated when any input state and is used to indicate the system master that an input state has changed. The power-on reset sets the registers to their default values and initializes the device state machine. The Reset pin causes ...
