MONO_WITH_NORMALLY_ONLED

Connection shown for three gates of 7400 quad NAND gate inverts operating mode, so LED is normally on. Trigger pulse at input extinguishes LED for time determined by R1 and C1 while making gates change states. Gates revert to original states after delay also determined by values of R1 and C1.-F. M.
