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.
Electrical Specifications
All typical values are for +25°C ambient temperature 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. Bit 7 in
control register 0 is “1”, while other bits in control registers are “0”. 400kHz TTL input at SCL. SDA pulled to V_CC
through an external 2kΩ resistor. 2-wire interface in “standby” (Notes 2 and 3 ). WP, A0, A1, and A2 floating.

2. The device goes into Standby: 200 ns after any STOP, except those that initiate a nonvolatile write cycle. It goes into Standby t_WC after a STOP
that initiates a nonvolatile write cycle. It also goes into Standby 9 clock cycles after any START that is not followed by the correct Slave Address
Byte.
3. t_WC is the time from a valid STOP condition at the end of a write sequence to the end of the self-timed internal nonvolatile write cycle. It is the
minimum cycle time to be allowed for any nonvolatile write by the user, unless Acknowledge Polling is used.
4. This parameter is periodically sampled and not 100% tested.
