Pin Description
Serial Data Address: This is a bi-directional data pin for the two-wire interface. It
employs an open-drain output and is intended to be wire-OR’d with other devices on the
two-wire bus. The input buffer incorporates a Schmitt trigger for noise immunity and the
output driver includes slope control for falling edges. A pull-up resistor is required.
Serial Clock: The serial clock input for the two-wire interface. Data is clocked-out on
the falling edge and clocked-in on the rising edge.
Write Protect: When WP is high, the entire array is write-protected. When WP is low,
all addresses may be written. This pin is internally pulled down.
