Note 6:
Input and output parameters vary 1 to 1 with V

0.8V/
0.5V.
Note 7:
Outputs are terminated through a 50
Resistor to V

Note 8:
V
IHCMR
minimum varies 1 to 1 with V
EE
. V
IHCMR
maximum varies 1 to 1 with V
CC
. The V
IHCMR
range is referenced to the most positive side of the dif-
ferential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between V
PPMIN
and
1V.
Note 9:
Absolute value of the input HIGH and LOW current should not exceed the absolute value of the stated Min or Max specification.
Note:
Devices are designed to meet the DC specifications after thermal equilibrium has been established. Circuit is tested with air flow greater than
500LFPM maintained.

Note 12:
Within-device skew defined as identical transitions on similar paths through a device.
Note 13:
Duty cycle skew is the difference between a t
PLH
and t
PHL
propagation delay through a device under identical conditions.
