DESCRIPTION
The M54/74HC42 is a high speed CMOS BCD-TO-
DECIMAL DECODER fabricated in silicon gate
C
2
MOS technology.
It has the same high speed performance of LSTTL
combined with true CMOS low power consumption.
A BCD code applied to the four inputs A-D selects
one of ten decimal outputs Y0-Y9, which goes low
to fifteen gives ahigh level atall outputs.Thisdevice
alsocanbeusedasa3-to-8LINEDECODER,when
the D input is assignedas a disable input. Thisde-
vice is useful for code conversion, address decod-
ing, memory selection, demultiplexing, or readout
decoding.
Allinputs areequipped withprotection circuitsagainst
staticdischarge and transient excess voltage.
