*This is a stress rating only and functional operation of the device at these
or any other conditions above those indicated in the operation sections of
this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods of time may affect reliability.
Notes
1. Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referred to ground unless otherwise specified. For current,
minimum and maximum values are specified as an absolute value and the sign is used to indicate direction. For voltage logic levels, the more positive value is designated
as maximum. For example, if -6V is a maximum, the typical value (-6.8V) is more negative.
2. All typicals are given for V

3. Only one driver output shorted at a time.

5. Generator characteristics for receiver input: f = 64kHz (128 kbits/sec), t
= t
= 200ns, V
= 3V, V
= -3V, duty-cycle = 50%.
6. If receiver inputs are unconnected, receiver output is a logic high.
7. Refer to typical curves. Driver output slew rate is measured from the +3.0V to the -3.0V level on the output waveform. Inputs not under test are connected to VCC
or GND. Slew rate is determined by load capacitance. To comply with a 30V/μs maximum slew rate, a minimum load capacitance of 390pF is recommended.
