RXVDD for RXD±, RRCLK±, and ALOS±, RXDO±; TXVDD for TRCLK±, TXD± and TXC±.
Current flowing out of the chip has a positive value, current flowing into the chip has a negative value.
Maximum leakage current of INTB output at V
Tested one output at a time, output shorted for less than one second, less than 10% duty cycle.
Typical is 0.75V
