ICS83947I-147
LOW SKEW, 1-TO-9
LVCMOS/LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS83947I-147 is a low skew, 1-to-9
LVCMOS/LVTTL Fanout Buffer and a member of
the HiPerClockS family of High Performance
Clock Solutions from ICS. The low impedance
LVCMOS/LVTTL outputs are designed to drive 50
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.
