1. stresses beyond those listed absolute maximum ratings may cause permanent damage to the device.

2. exposure to absolute-maximum-rated conditions for extended periods may affect the device reliability

3. by internal clamp between 4.75 V and 5.25 V or Vcc + 0.6 V, whichever is lower

4. the AMR value is intended when VCC ≥ 5 V, otherwise the value VCC + 0.3 V has to be considered.

5. when mounted on a standard single side FR4 board with 100 mm² (0.155² inch) of Cu (35 μm thick)
