Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
All currents into device pins are positive; all currents out of device
pins are negative; all voltages are referenced to GND unless otherwise
noted.
Note 3:
A substrate diode limits the V
IN
pin to a minimum of –0.3V with
respect to GND. This pin may go below –0.3V with current limited to less
