10-bit bidirectional low voltage translator
8.2 Unidirectional down translation
For unidirectional clamping, higher voltage to lower voltage, the GREF input must be
connected to DREF and both pins pulled to the higher side V
CC
through a pull-up resistor
(typically 200 k
). A filter capacitor on DREF is recommended. Pull-up resistors are
required if the chip set I/Os are open-drain. The opposite side of the reference transistor
(SREF) is connected to the processor core supply voltage. When DREF is connected
through a 200 k
resistor to a 3.3 V to 5.5 V V
CC
supply and SREF is set between 1.0 V
to (V
CC
1.5 V), the output of each Sn has a maximum output voltage equal to SREF.
8.3 Unidirectional up translation
For unidirectional 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 (SREF) 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.
