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 2A per channel, a range of 5.5 to 22V is allowed for any allowable RL (for ranges where Pd max is not
exceeded).
