MC14028B
BCD-To-Decimal Decoder
Binary-To-Octal Decoder
The MC14028B decoder is constructed so that an 8421 BCD code
on the four inputs provides a decimal (oneoften) decoded output,
while a 3bit binary input provides a decoded octal (oneofeight)
code output with D forced to a logic “0”. Expanded decoding such as
binarytohexadecimal (oneofsixteen), etc., can be achieved by
using other MC14028B devices. The part is useful for code
conversion, address decoding, memory selection control,
demultiplexing, or readout decoding.
Features

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
1. Temperature Derating: Plastic “P and D/DW”
Packages: – 7.0 mW/_C From 65_C To 125_C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
highimpedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either VSS or VDD). Unused outputs must be left open.

APPLICATIONS INFORMATION
Expanded decoding can be performed by using the
MC14028B and other CMOS Integrated Circuits. The
circuit in Figure 2 converts any 4bit code to a decimal or
hexadecimal 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 4bit binary, 4bit gray, excess3, or excess3 gray
codes as 7, 5, 4, or 2, respectively. Figure 3 shows a 6bit
binary 1of64 decoder using nine MC14028B circuits and
two MC14069UB inverters.
The MC14028B can be used in decimal digit displays,
such as, neon readouts or incandescent projection indicators
as shown in Figure 4.
