BCD−To−Decimal Decoder
Binary−To−Octal Decoder
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.
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.
