APPLICATIONS INFORMATION
TIME–BASE GENERATOR
A 60 Hz sinewave obtained through a 1.0 Megohm resistor
connected directly to a standard 120 Vac power line is
applied to the clock input of the MC14040B. By selecting
outputs Q5, Q10, Q11, and Q12 division by 3600 is ac-
complished. The MC14012B decodes the counter outputs,
produces a single output pulse, and resets the binary count-
er. The resulting output frequency is 1.0 pulse/minute.
