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.
