Interrupt Output, Active Low. INT is an open-drain output.
Reset Input, Active Low. Drive RST low to clear the 2-wire interface.
Address Inputs. Select device slave address with AD0 and AD2. Connect AD0 and AD2
to either GND, V+, SCL, or SDA to give four logic combinations (see Tables 2 and 3).
Output Ports. These push-pull outputs are rated at 20mA.
Input Ports. I2 and I5 are CMOS-logic inputs protected to +6V.
