SK4410
Quad Buffer/Receiver
HIGH-PERFORMANCE PRODUCTS
Description
ꢀeatures
The SK4410 is an extremely fast, stable and accurate
low skew quad buffer or cable driver / receiver. It can
asychronously pass four distinct signals, or it can
resynchronize them to a common clock. In addition, all
four outputs may be asynchronously enabled or
disabled. All of the D flip-flops are triggered on the
rising edge of the CLK input.

Application Notes
The SK4410 has 100Ω input termination resistors
across each of the four inputs to help reduce system
component count and increase integration.
