8-bit I2C-bus and SMBus I/O port with interrupt, 2-kbit EEPROM
Remark: Rapid fall-off in VOH at current inception is due to a diode that provides 5 V
overvoltage protection for the GPIO I/O pins. When the GPIO I/Os are being used as
inputs, the internal current source VOH should be evaluated to determine if external pull-up
resistors are required to provide sufcient VIH threshold noise margin.
