Storage temperature range, TSTG –65 to 150°C Lead temperature (soldering, 10 s), 300°C TSOLDER (1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum–rated conditions for extended periods may affect device reliability. RECOMMENDED OPERATING CONDITIONS Over operating free-air temperature range (unless otherwise noted) PARAMETER MIN NOM MAX UNIT Supply voltage, VDD (1) 3 20 V Input voltage V4–V3, V3–V2, V2–V1, V1–VSS, or CD–VSS 0 5 V range Operating ambient temperature range, TA –40 110 °C (1) See APPLICATION SCHEMATIC. DC CHARACTERISTICS Typical values stated where TA = 25°C and VDD = 14.4 V, MIN/MAX values stated where TA = –40°C to 110°C and VDD = 3 V to 20 V (unless otherwise noted).
