OPERATION DESCRIPTION
50Hz/60Hz Input:
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 counter
advance instead of "50/60Hz input". The values of CR determine the
frequency of the on-chip clock oscillator. All segment outputs are off during
backup oscillator operation.
NOTE: If the backup OSC is used at the power-down mode, "50/60Hz
input" must be
open or at Vss level.
Connecting "50/60Hz select" to Vss enables 50Hz operation. For 60Hz
operation, "50/60Hz select" is left unconnected: Pull-down to V
DD
is provided
by the internal pulldown resister.
The internal pull-down resistor allows the use of 2 SPST (single-pole single-
throw) switches to select 4 display modes listed in Table 1.
