Description
Logic Control Input.
Active High Digital Input. When low, the device is disabled and all switches are off. When high,
Ax logic inputs determine on switches.
Most Negative Power Supply Potential. In single-supply applications, this pin can be connected
to ground.
Source Terminal 1A. This pin can be an input or an output.
Source Terminal 2A. This pin can be an input or an output.
Source Terminal 3A. This pin can be an input or an output.
Source Terminal 4A. This pin can be an input or an output.
Drain Terminal A. This pin can be an input or an output.
Drain Terminal B. This pin can be an input or an output.
Source Terminal 4B. This pin can be an input or an output.
Source Terminal 3B. This pin can be an input or an output.
Source Terminal 2B. This pin can be an input or an output.
Source Terminal 1B. This pin can be an input or an output.
Most Positive Power Supply Potential.
Ground (0 V) Reference.
Logic Control Input.
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
