AC ELECTRICAL CHARACTERISTICS (See Figure 2)
(VCC = +2.7V to 5.5V, TA = -40°C to +85°C, unless otherwise noted. Timing referenced to VIL(MAX) and VIH(MIN).)
Note 1: All voltages referenced to ground.
Note 2: ISTBY CC, resistor pins floating, and inputs tied to VCC or GND.
Note 3: The DS3906 will not obstruct the SDA and SCL lines if VCC is switched off as long as the voltages applied to these input do
not violate their minimum and maximum input voltage levels.
Note 4: Tested with external resistor of 87
for R0 and R1 and 258 for R2 at 25°C.
Note 5: Timing shown is for fast mode (400kHz) operation. This device is also backward compatible with I
2C standard mode timing.
Note 6: CB
total capacitance of one bus line in picofarads.
Note 7: The EEPROM write time begins after a stop condition occurs.
Note 8: Guaranteed by design.
