In this mode, the 31 RAM registers can be consecutively read or written starting with bit 0 of address 0. Note: PT7C4302 use 94H, 96H as test mode address. Customer should not use the address. Maximum Ratings StorageTemperature.......................................................................................................................-65oCto +150oC AmbientTemperaturewithPowerApplied...........................................................................-40oCto +85oC SupplyVoltagetoGroundPotential(VcctoGND) ..........................................................-0.3Vto +6.5V DCInput(AllOtherInputsexceptVcc&GND)................................................................-0.3Vto +6.5V DCOutputVoltage(SDA,/INTA,/INTBpins)..................................................................-0.3Vto +6.5V PowerDissipation............................................................................................................................320mW(Dependon package) Note: Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Recommended Operating Conditions Symbol Description Min Type Max Unit VCC1,VCC2 Power voltage. VCC = VCC2, when VCC2 > VCC1 + 0.2; VCC = VCC1, when VCC1 > VCC2. 2 - 5.5 VIH Input high level 2 - VCC+0.3 VIL Input low level -0.3 - 0.3 V TA Operating temperature -40 - 85 ºC |
