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
IOSa and IOSb values are for one output at a time If more than one output is shorted simultaneously the device power dissipation may be exceeded
Note 4
Receiver AC input waveform for test purposes tr e tf e 200 ns VIH e 3V VIL eb3V f e 64 kHz (128 kbitssec) Driver AC input waveform for test
purposes tr e tf s 10 ns VIH e 3V VIL e 0V f e 64 kHz (128 kbitssec)
Note 5
All typicals are given for VCC e 50V and TA ea25 C Va e 1035V
Note 6
Ratings apply to ambient temperature at a25 C Above this temperature derate N package 20 mW C and WM package 135 mW C
