FUNCTION
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 3).
Reset Input, Active Low. Drive RST low to clear the 2-wire interface.
Input Ports. I0 to I7 are CMOS logic inputs protected to +6V.
Ground
Interrupt Output, Active Low. INT is an open-drain output rated at +6V.
I2C-Compatible Serial Clock Input
I2C-Compatible Serial Data I/O
Positive Supply Voltage. Bypass V+ to GND with a ceramic capacitor of at least 0.047µF.
Exposed Pad. Connect exposed pad to GND.
