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
