Resistor-transistor Logic




Resistor-transistor logic ('''RTL''') is a class of Digital Circuit s built from Bipolar Junction Transistor s (BJT), and Resistor s; it is the earliest transistorized digital logic used. Its main limitation was its limited Fanin , 3 inputs being the limit for many circuit designs, before it completely lost usable noise immunity.
