ICS85214I
LOW SKEW, 1-TO-5
DIFFERENTIAL-TO-HSTL FANOUT BUFFER
SCHEMATIC EXAMPLE
Figure 4 shows a schematic example of the ICS85214I. In
this example, the input is driven by an ICS HiPerClockS HSTL
driver. The decoupling capacitors should be physically located
near the power pin. For ICS85214I, the unused outputs can
be left floating.
