The HA1631S01/02/03/04 are low power single CMOS Comparators featuring low voltage operation with typical current supply of 5 µA/50 µA. They are designed to operate from a single power supply. HA1631S01/02 have push-pull full swing outputs that allow direct connections to logic devices. The Open Drain version HA1631S03/04 enable Output Level shifting through external pull up resistors. Available in an ultra-small CMPAK-5 package, they occupy only 1/8 the area of the SOP-8 package.
The document describes the HA1631S01/02/03/04 series as low power single CMOS comparators featuring low voltage operation with a typical supply current of 5 µA or 50 µA. The series includes push-pull full swing output versions (HA1631S01/02) and open drain output versions (HA1631S03/04), designed to operate from a single power supply between 1.8 V and 5.5 V.
