DESCRIPTION
The 74F711A/74F711-1 consist of five 2-to-1 multiplexers designed
for address multiplexing of dynamic RAMs and other multiplexing
applications. The 74F711A has a common select (S) input, an
Output Enable (OE
control the 3-State outputs. The outputs source 15mA and sink
64mA. The 74F711-1 is the same as the 74F711A except that is has
a 30 termination impedance on each output to reduce line noise
and the 3-State outputs sink 5mA.
When the inverting input (INV

used.
The 74F712A/74F712-1 consist of five 3-to1 multiplexers designed
for address multiplexing of dynamic RAMs and other multiplexing
applications. The 74F712A has two select (S0, S1) inputs to
determine which set of five inputs will be propagated to the five
outputs. The outputs source 15mA and sink 64mA. The 74F712-1 is
the same as the 74F712A except that it has a 30 termination
impedance on each output to reduce line noise and the outputs sink
5mA.
