Overview
Description
The 83905-01 is a low skew, 1-to-6 LVCMOS fanout buffer. The low-impedance LVCMOS outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 6 to 12 by utilizing the ability of the outputs to drive two series terminated lines.
The 83905-01 is characterized at full 1.8V, 1.5V, and 1.2V, mixed 1.8V/1.5V, 1.8V/1.2V, and 1.5V/1.2V output operating supply mode. Guaranteed output skew characteristics along with the 1.2V output capabilities make the 83905-01 ideal for high-performance, single-ended applications that also require a limited output voltage.
