to cut a long story (fairly) short, i have built a circuit the output stage of which is a 4013 d type triggering (at long intervals days or weeks) two 7555s configured as flip flops, each lighting an led. sinking.
the circuit works well (surprise surprise) my concern now is that the 7555s in quiescent standby mode are consuming .2 amps (as against the spec of 80 micro amps) ,not much i know, but i have limited space for batteries, so i would like to know if anyone has looked into this before or has any thoughts on this.
i have checked the 4013 (negligible consumption) and the 7555s peripheral componants are not taking any power.
maybe a complete power off of the 7555s somehow, between trigger pulses ?
