CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty
NOTE:
1. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
E^. lectrical Specifications
Conditions are as follows, unless otherwise specified. All typical values are for T_A = +25°C and 5V at pin V_CC.
Maximum and minimum specifications are over the recommended operating conditions. All voltages are
referred to the voltage at pin V_SS. All bits in control registers are “0”. 255Ω, 0.1%, resistor connected between
R₁ and V_SS, and another between R₂ and V_SS. 400kHz TTL input at SCL. SDA pulled to V_CC through an
external 2kΩ resistor. 2-wire interface in “standby” (see Notes 9 and 10 on page 5). WP, A0, A1, and A2 floating.
V_REF pin unloaded.
