SCL
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.
Device Select (S0, S1, S2)
The device select inputs (S0, S1, S2) are used to set the
second, third and fourth bits of the 8 bit slave address.
This allows up to eight X24164’s to share a common
bus. Theseinputscanbestaticoractivelydriven. Ifused
statically they must be tied to VSS or VCC as appropriate.
If actively driven, they must be driven to VSS or VCC. To
be compatible with the X24C16 these pins must all be
tied to VSS
