74F712A Quint 3-to-1 Data Selector Multiplexer

74F712-1 Quint 3-to-1 Data Selector Multiplexer with 30
Equivalent Output Termination Impedance

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
termination impedance on each output to reduce line noise and the 3-State outputs sink 5mA.
