AH342
ACTIVE HIGH/LOW COMPLEMENTARY OUTPUT
HALL-EFFECT LATCH
General Description
Features
The AH342 is
a bipolar latching hall IC with a pair of
•
•
Digital dual complementary sink/source outputs
Reverse Voltage Polarity protection for full supply
range.
High output current capability
Low profile packages: SIP-4L
Lead Free Package: SIP-4L
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.

Notes:
3. Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the electrical and
magnetic characteristics are not guaranteed as the maximum limits (above recommended operating conditions) are approached nor will the
device necessarily operate at absolute maximum rating.

Notes:
5. All the parameters are tested under the 25oC only. The operation temperature (-40oC to 125oC) is guaranteed by design, it is typical value.
6. The magnetic field strength (gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic
characteristics. To test the switch against the specified magnetic characteristics the switch must be placed in a uniform magnetic field.
