Description
Level comparator, NRZ comparator
and LVA comparator outputs. They are
open collectors.
(Applied voltage range: –0.5V to +7.0V)
Level comparator and NRZ comparator
inputs. The filter circuit output is
connected.
Controls the battery saving.
Setting this pin low suspends the
operation of IC.
