5. See the last page of this specification for Group A subgroup testing information.
6. These inputs are normally wired to V
7. CY7B991V is tested one output at a time, output shorted for less than one second, less than 10% duty cycle. Room temperature only.
8. Total output current per output pair is approximated by the following expression that includes device current plus load current:
