LOGIC_DRIVES_TRIAC

Published:2009/7/14 1:33:00 Author:May | From:SeekIC

H74C1 optoisolator combined with saturation characteristic of ordinary filament transformer serves to trigger full-wave triac on or off under control of logic input, for energizing AC loads up to rating of triac. Logic 0 (ground level) turns load on, and logic 1 turns it off.-D. D. Mickle, Practical Computer Projects, 73 Magazine, Jan. 1978, p 92-93.
