Input pins for device address selection. To configure a device address,
these pins should be connected to the V
These pins are internally pulled down to V
Ground pin.
Bi-directional data pin for the I
trigger input and open-drain output. An external pull-up resistor must
be connected to V Typical values for this pull-up resistor are 4.7 k

Schmitt trigger input pin for serial clock input.
Input pin for hardware write protection control. If you tie this pin to V
the write function is disabled to protect previously written data in the
entire memory; if you tie it to V
