Optically_coupled_RS_flip_flop

Published:2009/7/22 22:16:00 Author:Jessie | From:SeekIC

This circuit uses two 4N26 couplers to form an RS circuit with two stable states. A +2-V signal at the set input changes the output from low to high, and a +2-V signal at the reset input returns the output to low. The input pulse width must be 3 μs (minimum).
