APPLICATIONS INFORMATION
Expanded decoding can be performed by using the
MC14028B and other CMOS Integrated Circuits. The circuit
in Figure 2 converts any 4–bit code to a decimal or hexadeci-
mal code. The accompanying table shows the input binary
combinations, the associated “output numbers” that go “high”
when selected, and the “redefined output numbers” needed
for the proper code. For example: For the combination DCBA
= 0111 the output number 7 is redefined for the 4–bit binary,
4–bit gray, excess–3, or excess–3 gray codes as 7, 5, 4, or 2,
respectively. Figure 3 shows a 6–bit binary 1–of–64 decoder
using nine MC14028B circuits and two MC14069UB in-
verters.
The MC14028B can be used in decimal digit displays,
such as, neon readouts or incandescent projection indicators
as shown in Figure 4.
