COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; functional operation of the
device (at these or any other conditions above those
listed in the operational sections of this specification) is
not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.

ELECTRICAL CHARACTERISTICS
All typical values are for 25°C ambient temperature and 5 V at pin Vcc. Maximum and minimum specifications are
over the recommended operating conditions. All voltages are referred to the voltage at pin Vss unless otherwise
specified. All bits in control registers are “0” unless otherwise specified. 510¾, 0.1%, resistor connected between
R1 and Vss, and another between R2 and Vss unless otherwise specified. 400kHz TTL input at SCL unless
otherwise specified. SDA pulled to Vcc through an external 2K¾ resistor unless otherwise specified. 2-wire
interface in “standby” (see notes 1 and 2 on page 22), unless otherwise specified. WP, A0, A1, and A2 floating
unless otherwise specified. VRef pin unloaded, unless otherwise specified.
