Table 4. ADG508A Pin Function Description Pin Number DIP/SOIC PLCC/LCC Mnemonic Description
1 2 A0 Logic Control Input. 2 3 EN Active High Digital Input. When low, the device is disabled and all switches are off. When high, Ax logic inputs determine on switches. 3 4 VSS Most Negative Power Supply Potential in Dual Supplies. In single-supply applications, it can be connected to ground. 4 5 S1 Source Terminal 1. Can be an input or an output. 5 7 S2 Source Terminal 2. Can be an input or an output. 6 8 S3 Source Terminal 3. Can be an input or an output. 7 9 S4 Source Terminal 4. Can be an input or an output. 8 10 D Drain Terminal. Can be an input or an output. 9 12 S8 Source Terminal 8. Can be an input or an output. 10 13 S7 Source Terminal 7. Can be an input or an output. 11 14 S6 Source Terminal 6. Can be an input or an output. 12 15 S5 Source Terminal 5. Can be an input or an output. 13 17 VDD Most Positive Power Supply Potential. 14 18 GND Ground (0 V) Reference. 15 19 A2 Logic Control Input. 16 20 A1 Logic Control Input. N/A 1 NC No Connect. N/A 6 NC No Connect. N/A 11 NC No Connect. N/A 16 NC No Connect.
