Under absolute maximum conditions operation of microcircuits is not guaranteed. Operation under maximum conditions is guaranteed. *1 If VI < -0.5V or VI > VCC + 0.5 V. *2 If VO < -0.5V or VO > VCC + 0.5 V. *3 If -0.5V < VO < VCC + 0.5 V. *4 Under operation in the temperature range from 65 to 125C value of dissipation power drops down - to 10 mW/C for Plastic DIP - to 7 mW/C for SOIC
