Pin Function Descriptions Pin No.MnemonicDescription 1 VDD Most Positive Power Supply Potential. 2 DB Drain Terminal B. This pin can be an input or an output. 3, 13, 14 NC No Connect. 4 to 11 S8B to S1B Source Terminal 8B to Source Terminal 1B. These pins can be inputs or outputs. 12 GND Ground (0 V) Reference. 15 to 17 A2 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 S1A to S8A Source Terminal 1A to Source Terminal 8A. 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 DA Drain Terminal A. This pin can be an input or an output. Table 7. Truth Table (ADG407) A2A1A0ENOn Switch Pair X X X 0 None 0 0 0 1 1 0 0 1 1 2 0 1 0 1 3 0 1 1 1 4 1 0 0 1 5 1 0 1 1 6 1 1 0 1 7 1 1 1 1 8 Rev.
