6 Pin definitions and descriptions
Note: for +12V (+8…+16V) powered operation refer to the Application information section. For EMC and
isothermal conditions reasons it is highly recommended not to use any electrical connection to the metal can
except by the Vss pin.
With the SCL/Vz and PWM/SDA pins operated in 2-wire interface mode, the input Schmidt trigger function is
automatically enabled.
