ICS83947I-147
LOW SKEW, 1-TO-9
LVCMOS/LVTTL FANOUT BUFFER
APPLICATION SCHEMATIC EXAMPLE
Figure 1 shows an example of ICS83947I-147 application sche-
matic. In this example, the device is operated at V
CC=3.3V. The
decoupling capacitors should be located as close as possible
to the power pin. The input is driven by a 3.3V LVCMOS driver.

For the LVCMOS output drivers, only one termination example
is shown in this schematic. Additional termination approaches
are shown in the LVCMOS Termination Application Note (refer
