Integral IL8560
The on-chip Schmitt trigger circuit allows a simple RC filter at the input to remove possible line voltage transients. The values of CR determine the frequency of the on-chip clock oscillator.| Part No. | IL8560 |

DESCRIPTION
50Hz/60Hz Input: CR Input: 50/60 select input: Display mode select input (alarm display/sleep display); An internal pull-up resister is provided. Then AC power-down occurs, the time counter enters the "hold" mode and the on-chip clock oscillator starts operating immediately. If there is no input at "50/60 Hz input" during 3-clock period, this oscillator controls the time counter advance instead of "50/60Hz input". All segment outputs are off during backup oscillator operation.
