AC ELECTRICAL CHARACTERISTICS (continued)
(VCC = 3.0V to 5.5V, TA = -40°C to +95°C, unless otherwise noted.)
Note 11: After this period, the first clock pulse is generated.
Note 12: The maximum tHD:DAT only to has be met if the device does not stretch the LOW period (tLOW) of the SCL signal.
Note 13: A device must internally provide a hold time of at least 300ns for the SDA signal (see the VIH MIN of the SCL signal) in order
to bridge the undefined region of the falling edge of SCL.
Note 14: CB—total capacitance of one bus line, timing referenced to 0.9 x VCC and 0.1 x VCC.
Note 15: EEPROM write begins after a STOP condition occurs.
Typical Operating Characteristics
(VCC = 5.0V, TA = +25°C, unless otherwise noted.)
