VSS ......................................................................................................... -0.6V to VCC +1.0V Storage temperature ...............................................................................................................................-65°C to +150°C Ambient temperature with power applied ................................................................................................-65°C to +125°C ESD protection on all pins ......................................................................................................................................................≥ 4 kV TABLE 1-1: DC CHARACTERISTICS † NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. DC CHARACTERISTICS VCC = +2.5V to 5.5V Commercial (C): TA = 0°C to +70°C Industrial (I): TA = -40°C to +85°C Parameter Symbol Min Max Units Conditions DSCL, DSDA, MSCL & MSDA pins: High-level input voltage Low-level input voltage VIH VIL .7 VCC — — .3 VCC V V Input levels on VCLK/DWP pin: High-level input voltage Low-level input voltage VIH VIL 2.0 — .8 .2 VCC V V VCC ≥ 2.7V (Note) VCC < 2.7V (Note) Hysteresis of Schmitt Trigger inputs VHYS .05 VCC —V (Note) Low-level output voltage VOL1 —.4 V IOL = 3 mA, VCC = 2.5V (Note) Low-level output voltage VOL2 —.6 V IOL = 6 mA, VCC = 2.5V Input leakage current ILI —±1 µAVIN = .1V to VCC Output leakage current ILO —±1 µAVOUT = .1V to VCC Pin capacitance (all inputs/outputs) CIN, COUT —10 pF VCC = 5.0V (Note), TA = 25 °C, FCLK = 1 MHz Operating current ICC Write ICC Read — — 3 1 mA mA VCC = 5.5V, DSCL or MSCL = 400 kHz Standby current ICCS — — 60 200 µA µA VCC = 3.0V, DSDA or MSDA = DSCL or MSCL = VCC VCC = 5.5V, DSDA or MSDA = DSCL or MSCL = VCC VCLK = VSS Note: This parameter is periodically sampled and not 100% tested. |
