MM54C42 MM74C42 BCD-to-Decimal Decoder
General Description
The MM54C42 MM74C42 one-of-ten decoder is a mono-
lithic complementary MOS (CMOS) integrated circuit con-
structed with N- and P-channel enhancement transistors
This decoder produces a logical ‘‘0’’ at the output corre-
sponding to a four bit binary input from zero to nine and a
logical ‘‘1’’ at the other outputs For binary inputs from ten to
fifteen all outputs are logical ‘‘1’’

Note 1 ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
