Dalam elektronika, logika tergandeng–emitor atau sering disebut ECL adalah keluarga logika yang menggunakan transistor dwikutub dalam noda pengendalian arus untuk membuat fungsi logika. ECL kadang-kadang disebut logika moda-arus[2] atau logika sakelar-arus pengikut-emitor (CSEF).[3][4] Karakteristik utama dari ECL adalah kenyataan bahwa transistor tidak pernah sepada pada keadaan jenuh, sehingga dapat berganti keadaan dengan sangat cepat. Kerugian utamanya adalah kebutuhan arusnya yang malar, berarti ini membutuhkan banyak daya.

Sakelar arus Yourke, c. 1955.[5]

ECL ditemukan oleh Hannon S. Yourke pada tahun 1956.[6] Aslinya disebut logika pengendali arus yang digunakan pada komputer Stretch, IBM 7090, dan IBM 7094.[5]
