Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
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.
**When an output level of 400 mV is desired and VCC VEE > 3.0 V, a 2 kW resistor should be connected from OLS to VEE.
20.Input and output parameters vary 1:1 with VCC.
21.LVPECL outputs loaded with 50 W to VCC 2 V for proper operation.
22.Vth, VIH, VIL,, and VISE parameters must be complied with simultaneously.
23.Vth is applied to the complementary input when operating in singleended mode. Vth = (VIH VIL) / 2.
24.VIHD, VILD, VID and VCMR parameters must be complied with simultaneously.
25.VIHCMR min varies 1:1 with VEE, VIHCMR max varies 1:1 with VCC. The VIHCMR range is referenced to the most positive side of the differen-
tial input signal.
