PARAMETER
When the AC power supply is interrupted, the time counter switches to a holding state and a built-in
oscillator promptly begins operation. If 50/60Hz input continues for 3 clocks without arriving, this
oscillator’s output is activated and functions as the time counter clock in place of 50/60Hz input. The
frequency level of this clock oscillator is determined according to the CR value. While the above
mentioned oscillator is operating using backup mode, all segment output is switched to OFF.
left open, VDD is activated using an internal pull-down resistor and the setting is switched to enable use
at 60Hz.
Since the pull-down resistor is built-in , selection from four display modes is possible using two SPST
switches (single-pole and single-throw switches). Table 1 shows these display mode selections.
(Note) When the backup oscillator is in use due to an AC power supply interruption, the 50/60Hz input
pin must be maintained open or at a V
Built-in Shumidt circuit enables noise eliminations at 50/60Hz commercial frequencies with use of a
simple CR filter. Built-in pull-up resistor.
