Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltages are with respect to GND.

Operating virtual junction temperature, TJ
The device can deliver up to 220 mA at IO(IN2). However, operation at the higher current levels will result in greater voltage drop across the device,
and greater voltage droop when switching between IN1 and IN2.

Pulse-testing techniques maintain junction temperature close to ambient termperature; thermal effects must be taken into account separately.
