Quiet Series Dual 4-Input Multiplexer
General Description
Features
Y
Outputs source/sink 24 mA
The ’ACQ/’ACTQ153 is a high-speed dual 4-input multiplex-
er with common select inputs and individual enable inputs
for each section. It can select two lines of data from four
sources. The two buffered outputs present data in the true
(non-inverted) form. In addition to multiplexer operation, the
’ACQ/’ACTQ153 can act as a function generator and gen-
erate any two functions of three variables.
