Class Information
Number: 326/131
Name: Electronic digital logic circuitry > Function of and, or, nand, nor, or not > Bipolar transistor (e.g., rtl, dctl, etc.) > Diode-transistor logic (dtl) > With metal semiconductor junction diode (e.g., schottky barrier, etc.)
Description: Subject matter wherein the diode transistor logic device includes diodes of the type which operate on the principle of the injection of very highly concentrated (i.e., "hot") majority carriers across a potential difference barrier which is formed by the junction of a lightly doped semiconductor crystal and a metal layer deposited thereon.
