X9312 ABSOLUTE MAXIMUM RATINGS COMMENT
Temperature under bias .. -65°C to +135°C Stresses above those listed under “Absolute Maximum Storage temperature ... -65°C to +150°C Ratings” may cause permanent damage to the device. Voltage on CS, INC, U/D and VCC This is a stress rating only; functional operation of the with respect to VSS ... -1V to +7V device (at these or any other conditions above those ∆V = |VH - VL| ..15V listed in the operational sections of this specification) Lead temperature (soldering 10 seconds) ... 300°C is not implied. Exposure to absolute maximum rating IW (10 seconds) ...±8.8mA conditions for extended periods may affect device reliability.
