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 Pull-Up Resistor selection graph at the end of this data sheet.
Address (A0) A0 is unused by the X24042, however, it must be tied to VSS to insure proper devi...
