DESCRIPTION  
The M54/74HC4028 is a high speed CMOS BCD-  
TO-DECIMAL DECODER fabricated in silicon gate  
C2MOS technology. It has the same highspeed per-  
formance of LSTTL combined with true CMOS low  
power consumption. A BCD code applied to the four  
inputs (A to D) provides a high level at the selected  
one of the decimal decoded 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.  
NC =  
No Internal  
Connection  
All inputs are equipped with protection circuits  
against static discharge and transient excess volt-  
age.
