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−sixteen), 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.

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.

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
high−impedance 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.
