Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of “Electrical Characteristics provide conditions for actual device operation.
Note 2: Derate cavity package 8.7 mW/°C above 25°C.
Note 3: 35mA is more stringent than 30mA.
Note 4: Guaranteed by Vt- V_T test.
Note 5: Guaranteed by design.
Note 6: Guaranteed by V_OH & V_OL tests.
