Description

The 74F712-1 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 74F712-1 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) of the 74F712-1 is Low, the input data path is inverted.

To improve speed and noise immunity, VCC and GND side pins areused.

The 74F712-1 consist of five 3-to1 multiplexers designed for address multiplexing of dynamic RAMs and other multiplexing applications. The 74F712-1 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.
