ICS85214
LOW SKEW, 1-TO-5
DIFFERENTIAL-TO-HSTL FANOUT BUFFER
SCHEMATIC EXAMPLE
Figure 4 shows a schematic example of the ICS85214. 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 ICS85214, the unused outputs can be
left floating.
