DESCRIPTION
The M54/74HC4028 is a high speed CMOS BCD-
TO-DECIMAL DECODER fabricated in silicon gate
C
2
MOStechnology.Ithas thesame highspeedper-
formance of LSTTL combined with true CMOS low
powerconsumption. ABCDcodeapplied tothefour
inputs (A to D) provides a highlevel at the selected
one of thedecimaldecoded outputs. An illegal BCD
code such as eleven to fifteen gives a low level at
all outputs. The device also can be used as 3-TO-
8-LINE DECODER, when D input is assigned as a
disable input. The device is useful for code conver-
sion,address decoding, memory selection, demulti-
plexing, or read out decoding.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
