Pin Function Descriptions Pin No.MnemonicDescription 1 VDD Most Positive Power Supply Potential. 2, 3, 13 NC No Connect. 4 to 11 S16 to S9 Source Terminal 16 to Source Terminal 9. These pins can be inputs or outputs. 12 GND Ground (0 V) Reference. 14 to 17 A3 to A0 Logic Control Input. 18 EN Active High Digital Input. When this pin is low, the device is disabled and all switches are turned off. When this pin is high, the Ax logic inputs determine which switch is turned on. 19 to 26 S1 to 8 Source Terminal 1 to Source Terminal 8. These pins can be inputs or outputs. 27 VSS Most Negative Power Supply Potential. In single-supply applications, this pin can be connected to ground. 28 D Drain Terminal. This pin can be an input or an output. Table 5.
