PIN TYPE DESCRIPTION
NAME RSV NO. PW/SOIC NO.
A0 15 1 Digital input Address line 0
A1 14 16 Digital input Address line 1
A2 13 15 Digital input Address line 2
D 6 8 Analog input or output Drain pin. Can be an input or output.
EN 16 2 Digital input Active high digital input. When this pin is low, all switches are turned off. When this pin is high, the A[2:0] logic inputs determine which switch is turned on.
GND 12 14 Power supply Ground (0V) reference
S1 2 4 Analog input or output Source pin 1. Can be an input or output.
S2 3 5 Analog input or output Source pin 2. Can be an input or output.
S3 4 6 Analog input or output Source pin 3. Can be an input or output.
S4 5 7 Analog input or output Source pin 4. Can be an input or output.
S5 12 Analog input or output Source pin 5. Can be an input or output.
S6 9 11 Analog input or output Source pin 6. Can be an input or output.
S7 8 10 Analog input or output Source pin 7. Can be an input or output.
S8 7 9 Analog input or output Source pin 8. Can be an input or output.
VDD 11 13 Power supply Positive power supply. This pin is the most positive power-supply potential. For reliable operation, connect a decoupling capacitor ranging from 0.1µF to 10µF between VDD and GND.
VSS 1 3 Power supply Negative power supply. This pin is the most negative power-supply potential. In single-supply applications, this pin can be connected to ground. For reliable operation, connect a decoupling capacitor ranging from 0.1µF to 10µF between VSS and GND.
