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 transistor
