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.
Features
Digital dual complementary sink/source outputs
Reverse Voltage Polarity protection for full supply range
High output current capability
Low profile packages: SIP-4L
ADVANCED INFORMATION
Lead Free Package: SIP-4L
Lead-Free Finish; RoHS Compliant (Notes 1 & 2)
Notes: 1. EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. All applicable RoHS exemptions applied.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.

Note: 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.
