(2) All typical values are at nominal supply voltage (1.8-, 2.5-, 3.3-, or 5-V VCC), TA = 25°C. (3) RESET = VCC (held high) when all other input voltages, VI = GND. (4) The power-on reset circuit resets the I2C bus logic with VCC < VPORF. (5) Cio(ON) depends on internal capacitance and external capacitance added to the SCn lines when channels(s) are ON. 6.5 Electrical Characteristics (1) VCC = 2.3 V to 3.6 V, over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS VCC MIN TYP(2) MAX UNIT VPORR Power-on reset voltage, VCC rising No load, VI = VCC or GND (3) 1.2 1.5 V VPORF Power-on reset voltage, VCC falling(4) No load, VI = VCC or GND (3) 0.8 1 V Vo(sw) Switch output voltage Vi(sw) = VCC, ISWout = –100 μA 5 V 3.6 V 4.5 V to 5.5 V 2.6 4.5 3.3 V 1.9 3 V to 3.6 V 1.6 2.8 2.5 V 1.5 2.3 V to 2.7 V 1.1 2 1.8 V 1.1 1.65 V to 1.95 V 0.9 1.25 IOL SDA VOL = 0.4 V 1.65 V to 5.5 V 3 6 mA VOL = 0.6 V 6 9 II SCL, SDA VI = VCC or GND (3) 1.65 V to 5.5 V –1 1 μA SC7–SC0, SD7–SD0 –1 1 A2–A0 –1 1 RESET –1 1 ICC Operating mode fSCL = 400 kHz VI = VCC or GND (3), I O = 0 5.5 V 50 80 μA 3.6 V 20 35 2.7 V 11 20 1.65 V 6 10 fSCL = 100 kHz VI = VCC or GND (3), I O = 0 5.5 V 9 30 3.6 V 6 15 2.7 V 4 8 1.65 V 2 4 Standby mode Low inputs VI = GND (3), I O = 0 5.5 V 0.2 2 3.6 V 0.1 2 2.7 V 0.1 1 1.65 V 0.1 1 High inputs VI = VCC, IO = 0 5.5 V 0.2 2 3.6 V 0.1 2 2.7 V 0.1 1 1.65 V 0.1 1 ΔICC Supply-current change SCL, SDA SCL or SDA input at 0.6 V, Other inputs at VCC or GND (3) 1.65 V to 5.5 V 3 20 μA SCL or SDA input at VCC – 0.6 V, Other inputs at VCC or GND (3) 3 20 Ci A2–A0 VI = VCC or GND (3) 1.65 V to 5.5 V 4 5 pF RESET 4 5 SCL VI = VCC or GND (3), Switch OFF 20 28 Cio(off) (5) SDA VI = VCC or GND (3), Switch OFF 1.65 V to 5.5 V 20 28 pF SC7–SC0, SD7–SD0 5.5 7.5 |
