1.3 Pin Descriptions
Serial Clock (SCL): The SCL input is used to positive-edge clock data in and negative-edge clock data out of
each device.
Serial Data (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open drain driven and may
be wire-ORed with any number of other open-drain or open-collector devices.
Device Addresses (E2, E1, E0): The E2, E1, and E0 pins are device address inputs. Typically, the E2, E1,
and E0 pins are for hardware addressing and a total of 8 devices can be connected on a single bus system. If
these pins are left floating, the E2, E1, and E0 pins will be internally pulled down to GND.
Write Control (WCB): The Write Control input, when WCB is connected directly to V
CC
, all write operations to
the memory are inhibited. When connected to GND, allows normal write operations. If the pin is left floating,
the WCB pin will be internally pulled down to GND.

NOTICE: Stresses above those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of
the device at those or any other conditions above those
indicated in the operational listings of this specification is not
implied. Exposure to maximum rating conditions for extended
periods may affect device reliability.
