here's the general circuit functionality.
i monitor some pulses which advances a 4 bit counter. when bit 1 (0,1,2,3) goes high i need to latch a LED on even if the counter continues and bit 1 goes low.
there are 8 pulses i monitor, hence 8 counters and 8 LED's.
currently i use bit 1 output to trigger the gate of a scr which means i have 8 scr's too (discrete components, argh). in some cases several LED's will need to latch on so i need a way to manually reset them to a off state (a reset of all is required). startup needs to be latched low, etc.
so, is there a IC (logic) that may do this functionality better than using scr's ?
