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 and Output parameters vary 1:1 with VCC.
6. LVPECL outputs loaded with 50 W to VCC 2V for proper operation.
7. Vth, VIH, VIL,, and VISE parameters must be complied with simultaneously.
8. Vth is applied to the complementary input when operating in singleended mode.
9. VIHD, VILD, VID and VCMR parameters must be complied with simultaneously.
10.VCMR min varies 1:1 with GND, VCMR max varies 1:1 with VCC. The VCMR range is referenced to the most positive side of the differential
input signal.
