Application

Figure 3. Typical Application

VCC

VPU1

VPU2

1.8V

1.5V-5.5V

1.2V-5.5V

2.5V

1.8V-5.5V

3.3V

2.7V-5.5V

4.5V-5.5V

Note:

If the device generating the interrupt has an open-drain output structure or can be 3-stated, a pull-up resistor is required.

If the device generating the interrupt has a totem pole output structure and cannot be 3-stated, a pull-up resistor is not required.

The interrupt inputs should not be left floating.
