DESCRIPTION
The 74F723A/74F723-1 consist of four 3-to-1 multiplexers designed
for address multiplexing of dynamic RAMs and other multiplexing
applications. Select (S0, S1) inputs control which line is to be
selected, as defined in the Function Table for 74F723A/74F723-1.
When the invering input (INV
To improve speed and noise immunity, VCC and GND side pins are
used. The 3-State outputs source 15mA and sink 64mA. The
) is Low, the input data path is inverted.
74F723-1 is the same as 74F723A except that it has a 30
temination impedance on each output to reduce line noise and the
3-State outputs sink 5mA.
The 74F725A/74F725-1 consist of four 4-to1 multiplexers designed
for general multiplexing purpose. The select (S0, S1) inputs control
which line is to be selected, as defined in the Function Table for
74F725A/725-1. The outputs source 15mA and sink 64mA. The
74F725-1 is the same as the 74F725A except that it has a 30
termination impedance on each output to reduce line noise and the
outputs sink 5mA.
