noun
Direct-coupled Transistor Logic; DCTL
A specific type of digital logic family used in early transistor-based circuits. Technical term in computing and electronics.
直結形トランジスタ論理回路は、初期のコンピュータで使われた技術の一つです。
Direct-coupled Transistor Logic is one of the technologies used in early computers.
TTL (Transistor-Transistor Logic) is a later and more widely used logic family, while DCTL is an earlier, simpler direct-coupled design.
Compound of 直結形 (direct-coupled type), トランジスタ (transistor), and 論理回路 (logic circuit). The term is a direct translation of the English 'Direct-coupled Transistor Logic'.
