Function and pinout compatible with Fairchild F100K
s
Available in 28-pin PLCC packages
The SY100S371 is an ultra-fast triple 4-input multiplexer
with true and complementary outputs designed for use in
high-performance ECL systems. The multiplexer is
controlled by common select inputs S
0
and S
1
. A logic
HIGH on the Enable (E) control input takes the outputs to
a logic LOW. The inputs on the device have 75kΩ pull-
down resistors.
