Notes:
6. Exceeding the absolute maximum ratings may damage the device.
7. The device is not guaranteed to function outside its operating ratings.
8. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5kΩ in series with 100pF.
9. Specification for packaged product only
10. VDD equals nominal “Typical Application (VDD)” as shown in the Standard Voltage Options table.
11. VDD operating range is 1.5V to 5.5V. Output is guaranteed to be asserted down to VDD = 1.2V.
