ABSOLUTE MAXIMUM RATINGS (Note 1)
Note 1: All voltages are with respect to GND. All currents are
positive into the specified terminal. Consult Unitrode Integrated
Circuits databook for information regarding thermal specifica-
tions and limitations of packages.
Note 2: In normal operation VCC is powered through a current
limiting resistor. Absolute maximum of 12V applies when VCC
is driven from a low impedance source such that ICC does not
exceed 30mA. The resistor should be sized so that the VCC
voltage under operating conditions is below 12V but above the
turn off threshold.
