[1] This specification applies over the full operating temperature range.
[2] The enable time can slow considerably for some parts when temperature is < −20 °C.
[3] Delays that can occur after ENABLE and/or idle times have passed.
[4] Guaranteed by design, not production tested.
[5] I_trt(pu) varies with temperature and V_CC voltage, as shown in Section 11.1 “Typical performance characteristics”.
[6] The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function
of the pull-up resistor and V_CC voltage is shown in Section 11.1 “Typical performance characteristics”.
[7] C_b = total capacitance of one bus line in pF.
[8] Force V_SDAIN = V_SCLIN = 0.1 V, tie SDAOUT and SCLOUT through 10 kΩ resistor to V_CC and measure the SDAOUT and SCLOUT
output.
