DESCRIPTION
The M74HC42 is an high speed CMOS BCD TO
DECIMAL DECODER fabricated with silicon gate
C
2
MOS technology.
A BCD code applied to the four inputs A-D selects
one of ten decimal outputs Y0 - Y9, which goes
low to fifteen gives a high level at all outputs. This
device also can be used as a 3 to LINE
DECODER, when the D input is assigned as a
disable input. This device is useful for code
conversion, address decoding, memory selection,
demultiplexing, or readout decoding.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
