DS70010I-page 7 AY0438 2.0 ELECTRICAL CHARACTERISTICS Maximum Ratings* VDD.............................................................................................................................................................. -0.3V to +12V Inputs (CLK, Data In, Load) ................................................................................................................. VCC to VDD +0.3V LCD Φ Input ........................................................................................................................................ -0.3V to VDD +0.3V Power Dissipation.................................................................................................................................................250 mW Storage Temperature............................................................................................................................... -65˚C to +125˚C Operating Temperature Industrial.............................................................................................................. -40˚C to +85˚C * Exceeding these ratings could cause permanent damage to the device. This is a stress rating only and functional operation of this device at these conditions is not implied. Operating ranges are specified in Standard Conditions. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Data labeled “typical” is presented for design guidance only and is not guaranteed.
