ACTIVE HIGH/LOW COMPLEMENTARY OUTPUT HALL-EFFECT LATCH
Description
The AH342 is a bipolar latching hall IC with a pair of complementary
push/pull outputs. A dual hall element is used to offset stress induced
noise and drift. The robust outputs are capable of sourcing up to
7.4mA and sinking up to 4.4mA. The device contains inherent reverse
polarity protection up to the full power supply range.
