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).
Open-Drain I/O Ports
Ground
Output Ports. O8–O15 are push-pull outputs rated at 20mA.
