1. THE EXPOSED PAD IS CONNECTED INTERNALLY.
FOR INCREASED RELIABILITY OF THE SOLDER
JOINTS AND MAXIMUM THERMAL CAPABILITY,
IT IS RECOMMENDED THAT THE PAD BE
SOLDERED TO THE SUBSTRATE, V

Active High Digital Input. When low, the device is disabled and all switches are off. When high, Ax logic inputs
determine on switches.
EPAD
Exposed Pad. The exposed pad is connected internally. For increased reliability of the solder joints and maximum
thermal capability, it is recommended that the pad be soldered to the substrate, V
