APPLICATIONS
Bi-directional translation
For the bi-directional clamping configuration, higher voltage to lower voltage or lower voltage to higher voltage, the G
REF
input must be
connected to D
REF
and both pins pulled to high side V
CC
through a pull-up resistor (typically 200 k
). A filter capacitor on D
REF
is
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
CC
). However, if either output is totem pole, data must be
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 (S
REF
)
is connected to the processor core power supply voltage. When D
REF
is connected through a 200 k
resistor to a 3.3 V to 5.5 V V
CC
supply
and S
REF
is set between1.0 V to V
CC
- 1.5 V, the output of each Sn has a maximum output voltage equal to S
REF
and the output of each Dn
has a maximum output voltage equal to V
CC
.
