The SY10/100E171 offer three 4:1 multiplexers with
differential outputs, designed for use in new, high-
performance ECL systems. The leading 4-bit multiplexer
operation is organized pairwise, with each pair being a 2-
bit multiplexer. Separate select (SEL
1A
, SEL
1B
) controls
are provided within each pair. The SEL
1A
and SEL
1B
signals control the leading multiplexers, while the SEL
2
signal controls the output multiplexer. The three select
signals can be used to determine which of the four data
inputs will be propagated to the corresponding outputs.
