Description
50Hz/60Hz Input:
CR Input:
50/60 select input:
Display mode select input (alarm display/sleep display);
The on-chip Schmitt trigger circuit allows a simple RC filter at the input to remove possible line voltage transients.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 co
Features
- LED direct drive by time-sharing (duplex).
- Wide operating voltage range.
- Alarm on a 24-hour basis.
- Time format: 12-hour AM/PM and 24hour.
- On-chip RC-oscillator for battery backup.
- 50Hz or 60Hz is usable as the reference frequency.
- Possible to automatically advance "hours", "minutes".
- Sleep timer (max. 59 minutes or 1 hour 59 minutes).
- Repeatedly usable snooze.
