ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
Transient voltage for less than 10
μ
s. This parameter is not 100%
tested. Voltage should not exceed 200V between any two pins.
Note 3:
All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to RTN unless otherwise
specified.
