I've used a single 4060 with a 32.768khz crystal oscillator. Stepped down to 2Hz which was then given to a D flip flop to step down to 1hz. I'm using 4073 (3 input AND gates) to solve the problem of resetting the 4026s of the 10s minutes and the 10s seconds at 6. BUT... the problem is the output from the 4026 pins is 1.73V and minimum voltage required by the 4073 to detect a signal as high is 4.5V What should i do now?? leave all this and program a 8051 instead??
