However, precautions must in CC be taken to avoid applications of any V DC Output Voltage (Referenced to GND) 0.5 to V + 0.5 V out CC voltage higher than maximum rated I DC Input Current, per Pin 20 mA voltages to this highimpedance cir- in cuit. For proper operation, V and in I DC Output Current, per Pin 25 mA out V should be constrained to the out range GND (V or V ) V .

T Storage Temperature 65 to + 150 C stg T Lead Temperature, 1 mm from Case for 10 Seconds C L Plastic DIP and SOIC Package 260 Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
