Single CMOS Comparator (Push Pull/Open Drain Output)
REJ03D0056-0100Z
Rev.1.00
2003.08.08
Description
The HA1631S01/02/03/04 are low power single CMOS Comparator 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, th ey occupy only 1/8 the area of the SOP-8
package.
Features
