Abstract
A digital decoder for use with a dual bus system is provided having a minimum number of transistors. The decoder is easily expandable to decode larger binary coded input signals. As a minimum only six transistors are needed to decode a three-bit binary input signal to provide outputs for a data bus and its complement. By using a minimum number of transistors, less current is required for the decoder. The circuitry used to provide each decoded output is repeated in a manner which conserves silicon area when the decoder is placed on silicon. A minimum number of control lines are used.
