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, V
SS
.

TSSOP LFCSP Mnemonic Description
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.
4 2 S1 Source Terminal 1. Can be an input or an output.
5 3 S2 Source Terminal 2. Can be an input or an output.
6 4 S3 Source Terminal 3. Can be an input or an output.
7 5 S4 Source Terminal 4. Can be an input or an output.
8 6 D Drain Terminal. Can be an input or an output.
9 7 S8 Source Terminal 8. Can be an input or an output.
10 8 S7 Source Terminal 7. Can be an input or an output.

12 10 S5 Source Terminal 5. Can be an input or an output.
13 11 V
DD
Most Positive Power Supply Potential.
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
