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” specify conditions for device operation.
Note 2: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground unless otherwise
specified.
Note 3: I
Note 4: Receiver AC input waveform for test purposes: t

Note 5: All typicals are given for V
Note 6: Ratings apply to ambient temperature at +25˚C. Above this temperature derate: WM package 14.3 mW/˚C.
