GENERAL DESCRIPTION

The 83947I-147 is a low skew, 1-to-9 LVCMOS/LVTTL

Fanout Buffer. 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 83947I-147 ideal for high performance, 3.3V or 2.5V single

ended applications.
