FUNCTION
I/O Ports. Configure P0–P4 as open-drain current sink outputs rated at
20mA (max), as CMOS-logic inputs, or as open-drain logic outputs.
Connect loads to a supply voltage no higher than 7V.
Ground
I/O Ports. Configure P5–P9 as open-drain current sink outputs rated at
20mA (max), as CMOS-logic inputs, or as open-drain logic outputs.
Connect loads to a supply voltage no higher than 7V.
External Oscillator Input
Address Input. Sets the device slave address (see Table 10).
Active-Low Reset Input
Positive Supply Voltage. Bypass VDD to GND with a 0.1μF ceramic capacitor.
I 2 C-Compatible, Serial-Clock Input
I 2 C-Compatible, Serial-Data I/O
Exposed Pad on Package Underside. Connect to GND. Do not use as the
main ground connection.
