DESCRIPTION
The SY100S363 is a dual 8-input multiplexer designed
for use in new, high-performance ECL systems. The
three Data Select inputs (S
0, S1, S2) determine the bits
from each of the inputs (An, Bn) that will be passed on
through the two outputs. The same bit will be selected
from the two groups of 8 inputs. The inputs on this
device have 75KΩ pull-down resistors.
