Overview
Description
The 83947I is a low skew, 1-to-9 LVCMOS 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 byutilizing the ability of the outputs to drive two series terminated lines. Guaranteed output and part-to-part skew characteristics make the 83947I ideal for high performance, single ended applications that also require a limited output voltage.
