Serial Data (SDA) SDA is a bidirectional pin used to transfer d ata into and out of the device. It is a n open drain output and may be wire-ORe d with any number of open drain or open collector outputs. An open drain outpu t requires the use of a pull-up resisto r. For selecting typical values, refer to the Pull-Up Resistor selection graph at the end of this data sheet. Address (A0) A0 is unused by the
