Description
Negative Power Supply in a Dual-Supply Application. For single-supply applications, this pin should be tied to GND.
No Connect.
Can be inputs or outputs.
Positive Power Supply Input.
Logic Power Supply Input.
Digital Input, Serial Clock Line. Open drain input that is used in conjunction with SDA to clock data into the
device. External pull-up resistor required.
Logic Input. Address pin that sets the least significant bit of the 7-bit slave address.
Logic Input. Address pin that sets the second least significant bit of the 7-bit slave address.
Logic Input. Address pin that sets the third least significant bit of the 7-bit slave address.
Active Low Logic Input. When this pin is low, all switches are open, and appropriate registers are cleared to 0.
