PT7C4363BQ Maximum Ratings
Storage Temperature ... -65oCto +150oC Junction Temperature .. +125oC Max Supply Voltage to Ground Potential (Vcc to GND) .. -0.3V to +6.5V DC Input (All Other Inputs except Vcc & GND) ... -0.3V to (Vcc+0.3V) DC Output Voltage (SDA, /INTA, /INTB pins) .. -0.3V to +6.5V Power Dissipation .. 320mW
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.
