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. Outputs evaluated with 50 W resistors to VTT = VCC 2.0 V for proper operation (See Figure 16). 6. VTH is applied to the complementary input when operating in singleended mode. VIH, VIL and VTH parameters must be complied with
simultaneously.
7. VIHD, VILD and VCMR parameters must be complied with simultaneously. VCMR max varies 1:1 with VCC.
