2 / 10 page  Operating Conditions *1 at Ta = 25°C Note *:1. When used with VCC, RL, and output level ranges such that Pd max for the heat sink actually used is not exceeded. 2. When both channels are operating with IO peak values that exceed 2 A per channel. If the IO peak value does not exceed 2 A per channel, a range of 5.5 to 22 V is allowed for any allowable RL (for ranges where Pd max is not exceeded).
