Notes:

1. Minimum DC voltage is -0.5V on input/output pins. During Transitions, inputs may undershoot GND to -2.0V for periods up to 20ns. Maximum DC voltage on

3. No more than one output shorted to ground for no more than 1 second.

NOTICE: Stresses above those listed under "Absolute Maximums Rating" may cause permanent damage to the device. These are stress rating only; functional

operation beyond the "Operation Conditions" is not recommended and extended exposure beyond the "Operation Conditions" may effect device reliability.
