VCC
Positive Supply. All VCC Pins must be Externally Connected to Power Supply to
Guarantee Proper Operation.
EP
The Exposed Pad (EP) and the QFN16 package bottom is thermally connected to
the die for improved heat transfer out of package. The exposed pad must be attached
to a heatsinking conduit. The pad is not electrically connected to the die but may be
electrically and thermally connected to VEE on the PC board.
1. In the differential configuration when the input termination pins (VTD0, VTD1) are connected to a common termination voltage, and if no signal
is applied then the device will be susceptible to selfoscillation.
2. When an output level of 400 mV is desired and VCC VEE > 3.0 V, 2 kW resistor should be connected from OLS pin to VEE.
