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 Table 2).
Reset Input. Active Low. Drive RST low to clear the 2-wire interface.
Input Ports. I2 to I5 are CMOS-logic inputs protected to +6V.
Ground
Interrupt Output, Active Low. INT is an open-drain output.
