(1) TL, TH are device-specific. For example, TMP303A TL = 0°C, TH = 60°C; TMP303B TL = 0°C, TH = 55°C; TMP303C TL = –20°C, TH = 60°C; TMP303D TL = –15°C, TH = 125°C; TMP303E TL = 0°C, TH = 70°C; TMP303F TL = 0°C, TH = 80°C; TMP303G TL = 0°C, TH = 90°C
(2) 100% of all units are production tested at TA = 25°C. Over temperature specifications are specified by design.
