MM54C154/MM74C154 4-Line to 16-Line
Decoder/Demultiplexer
General Description
The MM54C154/MM74C154 one of sixteen decoder is a
monolithic complementary MOS (CMOS) integrated circuit
constructed with N- and P-channel enhancement transis-
tors. The device is provided with two strobe inputs, both of
which must be in the logical ‘‘0’’ state for normal operation.
If either strobe input is in the logical ‘‘1’’ state, all 16 outputs
will go to the logical ‘‘1’’ state.
To use the product as a demultiplexer, one of the strobe
inputs serves as a data input terminal, while the other strobe
input must be maintained in the logical ‘‘0’’ state. The infor-
mation will then be transmitted to the selected output as
determined by the 4-line input address.
