Supply
Positive power supply. All VCC and VCCO pins must be connected to
the positive power supply for correct DC and AC operation
VBB
Output
DC bias output for single ended input operation
a. In ECL mode (negative power supply mode), VEE is either -3.3V or -2.5V and VCC is connected to GND (0V).
In PECL mode (positive power supply mode), VEE is connected to GND (0V) and VCC is either +3.3V or +2.5V.
In both modes, the input and output levels are referrenced to the most positive supply (VCC).

a. Absolute maximum continuos ratings are those maximum values beyond which damage to the device may occur. Exposure to these conditions
or conditions beyond those indicated may adversely affect device reliability. Functional operation at absolute-maximum-rated conditions is not
implied.

a. Output termination voltage VTT = 0V for VCC=2.5V operation is supported but the power consumption of the device will increase.
b. Proper thermal management is critical for reliable system operation. This especially true for high-fanout and high drive capability products.
Thermal package information and exposed pad land pattern design recommendations are available in the applications section of this data-
sheet. In addition, the means of calculating die power consumption, the corresponding die temperature and the relationsship to long-term
reliability is addressed in the Motorola application note AN1545. Thermal modeling is recommended for the MC100EP221.
