VOH (Hi-Z)

1) X at RY/BY# is VOL or VOH(Hi-Z).

*The RY/BY# is an open drain output pin and indicates status of the internal WSM. When low,it indicates that the WSM is Busy performing an operation.

A pull-up resistor of 10K-100K Ohms is required to allow the RY/BY# signal to transition high indicating a Ready WSM condition.

2) X can be VIH or VIL for control pins.
