(1)
The device meets these 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 (2.54 m/s). Electrical parameters are assured 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.
(2)
Input and output parameters vary 1:1 with VCC. VEE can vary +0.25 V / –0.5 V.
(3)
Outputs are terminated through a 50-
resistor to VCC – 2 V.
(4)
VIHCMR min varies 1:1 with VEE; VIHCMR max varies 1:1 with VCC. The VIHCMR range is referenced to the more-positive side of the
differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies
between VPP min and 1 V.
