NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
5. Input parameters vary 1:1 with VCC. Measurements taken with outputs in either 1X (all outputs loaded 50 W to GND) or 2X (all outputs loaded
25 W to GND) configuration, see Figure 9. For 1X configuration, connect IREF to GND, or for 2X configuration, connect IREF to VCC.
6. Vth is applied to the complementary input when operating in single ended mode.
