Note:
Exceeding these ratings could cause damage to the device. All voltages are
with respect to Ground. Currents are positive into, negative out of specified
terminal.
The limitation on transient time is thermal and is due to zener diodes on the
supply pins, application of maximum voltages will increase current into that
pin and increase package power dissipation..
