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.
