The most significant input (A3) produces an useful inhibit function when the ’42’ is used as a 1-of-8 decoder. The A3 input can also be used as the data input in an 8-output demultiplexer application.

A long time ago when a parallel printer port was the standard, i was thinking how to get the most led’s on a 8 bit interface. And came up with a simpel way to demultiplex. It can be used with ...

BCD-to-Decimal 4bit relay decoder. This board was born from my passion for retrocomputers and electronics, as an electromechanical reinterpretation of a modern circuit with the aim of creating a set ...

Unpacked BCD. The lower four bits of the numbers represent BCD number. Only one byte of memory is required for unpacked BCD numbers or 8-bit register to contain it. In unpacked BCD numbers, upper bits ...

The four bit Binary Coded decimal form will normally be the output states of digital counters and thus they are not relevant for straightly activating 7 segment displays. The special BCD to 7 segment ...

Abstract: We have experimentally demonstrated a 40Gb/s all-optical binary-coded-decimal (BCD) decoder for the first time, utilizing delay interferometers (DIs) and cascading semiconductor optical ...
