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) input and an Output Inverting (INV) input to

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

W termination impedance on each output to reduce line noise

and the 3-State outputs sink 5mA.

When the inverting input (INV) is Low, the input data path is

inverted.

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

W termination

impedance on each output to reduce line noise and the outputs sink

5mA.
