1. θJA is measured with the component mounted on an evaluation PC board in free air.
2. Connecting any input terminal to voltages greater than V+ or less than GND may cause
destructive latchup. It is recommended that no inputs from sources operating from
external supplies be applied prior to “power up” of the TJ7660.
