PIN DESCRIPTIONS

Serial Clock (SCL)

The SCL input is used to clock all data into and out of the

device.

Serial Data (SDA)

SDA is a bidirectional pin used to transfer data into and out

of the device. It is an open drain output and may be

wire-ORed with any number of open drain or open

collector outputs.

An open drain output requires the use of a pull-up

resistor. For selecting typical values, refer to the Guide-

lines for Calculating Typical Values of Bus Pull-Up

Resistors graph.

The address inputs are used to set the least significant

three bits of the seven bit slave address. These inputs

can be static or actively driven. If used statically they must
