APPLICATIONS
Bi-directional translation
For the bi-directional clamping configuration, higher voltage to lower voltage or lower voltage to higher voltage, the G

recommended. The processor output can be totem pole or open drain (pull-up resistors may be required) and the chipset output can be totem
pole or open drain (pull-up resistors are required to pull the Dn outputs to V
uni-directional or the outputs must be 3-statable and the outputs must be controlled by some direction control mechanism to prevent
HIGH-to-LOW contentions in either direction. If both outputs are open drain, no direction control is needed. The opposite side of the reference
