Uni-directional down translation
For uni-directional clamping, higher voltage to lower voltage, the G
REF
input must be connected to D
REF
and both pins pulled to the higher side
V
CC
through a pull-up resistor (typically 200 k
). A filter capacitor on D
REF
is recommended. Pull up resistors are required if the chipset I/O are
open drain. The opposite side of the reference transistor (S
REF
) is connected to the processor core 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 between 1.0 V to V
CC
- 1.5 V, the output of each Sn has a maximum
output voltage equal to S
REF
.

Uni-directional up translation
For uni-directional up translation, lower voltage to higher voltage, the reference transistor is connected the same as for a down translation. A
pull-up resistor is required on the higher voltage side (Dn or Sn) to get the full high level, since the GTL-TVC device will only pass the reference
source (S
REF
) voltage as a high when doing an up translation. The driver on the lower voltage side only needs pull-up resistors if it is open
drain.
