8.4 Device Functional Modes

Table 8-1 High to Low Translation
(Assuming Dn is at the Higher Voltage Level)
GREF(1)DREFSREFINPUTS
D8–D1		OUTPUT S8–S1TRANSISTOR
HH0 VXXOff
HHVTT(2)HVTT(3)On
HHVTTLL(4)On
LL0 – VTTXXOff
(1) GREF should be at least 1.5 V higher than SREF for best translator operation.
(2) VTT is equal to the SREF voltage.
(3) Sn is not pulled up or pulled down.
(4) Sn follows the Dn input LOW.

D8–D1		OUTPUT S8–S1TRANSISTOR
HH0 VXXOff
HHVTT(2)VTTH(3)Nearly Off
HHVTTLL(4)On
LL0 – VTTXXOff
(1) GREF should be at least 1.5 V higher than SREF for best translator operation.
(2) VTT is equal to the SREF voltage.
(3) Dn is pulled up to VCC through an external resistor.
(4) Dn follows the Sn input LOW.
