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 (one–of–ten) decoded output,
while a 3–bit binary input provides a decoded octal (one–of–eight)
code output with D forced to a logic “0”. Expanded decoding such as
binary–to–hexadecimal (one–of–16), 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.
Diode Protection on All Inputs
Supply Voltage Range = 3.0 Vdc to 18 Vdc
Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range
Positive Logic Design
Low Outputs on All Illegal Input Combinations
Similar to CD4028B.

2. Maximum Ratings are those values beyond which damage to the device
may occur.
3. 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
v vhigh–impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS (Vin or Vout) 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.
