EP
The Exposed Pad (EP) on 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 electrically connected to the die, and must be
electrically and thermally connected to GND on the PC board.
1. In the differential configuration when the input termination pins (VT0, VT1) are connected to a common termination voltage or left open, and
if no signal is applied on IN0/IN0, IN1/IN1 inputs, then the device will be susceptible to selfoscillation. Q/Q outputs have internal 50 W source
termination resistors.
2. All VCC and GND pins must be externally connected to a power supply for proper operation.
