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 con-
ditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS (Conditions are as follows, unless otherwise specified)
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. All bits in control reg-
isters are “0”. 255Ω, 0.1%, resistor connected between R1 and Vss, and another between R2 and Vss. 400kHz TTL
input at SCL. SDA pulled to Vcc through an external 2kΩ resistor. 2-wire interface in “standby” (see notes 1 and 2 on
page 5). WP, A0, A1, and A2 floating. VRef pin unloaded
