Operating Conditions

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