TYPICAL APPLICATION
The circuit shown in fig. 1 converts any 4-bit code
to a decimal or hexadecimal code. Fig. 2 shows a
number of codes and the decimal or hexadecimal
number in these codes, which must be applied to
the input pins of HCF4028B to select a particular
output. For example: in order to get a "high" on
output 8 the input must be either an 8 expressed in
