Comparators
Input Full Swing, Open Drain Output
Low Supply Current CMOS Comparators
BU7230G BU7230SG BU7233F BU7233SF
General Description
BU7230G/BU7233F are input full swing and open
drain comparators. BU7230SG/BU7233SF have an
expanded operating temperature range. These
features low operating supply voltage of +1.8V to
+5.5V, low supply current and extremely low input bias
current.

(Note 11) Under the high temperature environment, consider the power dissipation of IC when selecting the output current.
When the terminal short circuits are continuously output, the output current is reduced to climb to the temperature inside IC.
