The 555 Timer IC
... One precaution that should be observed with the trigger input signal is that it must not remain lower than 1/3 V+ for a period of time longer than the timing cycle. If this is allowed to happen, the timer will retrigger itself upon termination of the first output pulse. Thus, when the timer is drive ...

... Inverters G1 and G2 are used as an astable multivibrator to provide the AC drive to the LCD backplane. Inverters G3, G4 and G5 are the digit-select inverters and require pull-up resistors to interface the open-collector outputs of the CA3162E to CMOS logic. The BCD outputs of the CA3162E may be conn ...
