NOTES
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,

1 15 A0 Logic Control Input.
2 16 EN
Active High Digital Input. When this pin is low, the device is disabled and all switches are off. When this pin
is high, Ax logic inputs determine on switches.
3 1 V
SS
Most Negative Power Supply Potential. In single-supply applications, this pin can be connected to ground.

14 12 GND Ground (0 V) Reference.
15 13 A2 Logic Control Input.
16 14 A1 Logic Control Input.
N/A EP EP
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
