EP
The Exposed Pad (EP) on the QFN16 package bottom is thermally connected to the die
for improved heat transfer out of package. The pad is not electrically connected to the die,
but is recommended to be electrically and thermally connected to VEE on the PC board.
1. In the differential configuration when the input termination pin (VTD, VTD, VTR, VTR, VTCLK, VTCLK) are connected to a common
termination voltage or left open, and if no signal is applied on D/D,CLK/CLK,R/R input then the device will be susceptible to selfoscillation.
