Notes:
a. Signals on SX, DX or INX exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
b. All leads soldered or welded to PC board.
c. Derate 8.0 mW/°C above 70 °C.
d. Derate 5.6 mW/°C above 70 °C.
e. Derate 6.3 mW/°C above 70 °C.
f. Derate 6.6 mW/°C above 70 °C.
