PT7C4563BQ Maximum Ratings
Storage Temperature .. -65°C to +150°C
Note:
Junction Temperature... +125°C Max Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. Supply Voltage to Ground Potential (Vcc to GND) .. -0.3V to +6.5V This is a stress rating only and functional operation of DC Input (All Other Inputs Except Vcc & GND)... -0.3V to (Vcc+0.3V) the device at these or any other conditions above those DC Output Voltage (SDA, /INTA, /INTB pins) ... -0.3V to +6.5V indicated in the operational sections of this specification Power Dissipation .. 320mW is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
