FEATURES for 74F723A/74F723-1
Consists of four 3-to-1 Multiplexers
High impedance PNP base inputs for reduced loading
(20
μ
A in High and Low states)
Inverting or non-inverting data path capability by an inverting (INV)
input
Designed for address multiplexing of dynamic RAM and other
applications
Multiple side pins for V
CC
and GND to reduce lead inductance
(improves speed and noise immunity)
3-State outputs sink 64mA (74F723A only)
30 termination impedance on each output – 74F723-1
FEATURES for 74F725A/74F725-1
Consists of four 4-to-1 Multiplexers
High impedance PNP base inputs for reduced loading
(20
μ
A in High and Low states)
Equivalent to two 74F253s without 3-State
Outputs sink 64mA (74F725A only)
30 termination impedance on each output – 74F725-1
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) is Low, the input data path is inverted.
To improve speed and noise immunity, V
CC
and GND side pins are
used. The 3-State outputs source 15mA and sink 64mA. The
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.
