The ICS83947I-147 is a low skew, 1-to-9 LVCMOS/LVTTL
Fanout Buffer. The low impedance LVCMOS/LVTTL outputs
are designed to drive 50Ω series or parallel terminated
transmission lines. The effective fanout can be increased from
9 to 18 by utilizing the ability of the outputs to drive two series
terminated lines.
Guaranteed output and part-to-part skew characteristics make
the ICS83947I-147 ideal for high performance, 3.3V or 2.5V
single ended applications.
