General Description
The UM3202Q/3202A/3202H is ±15kV dual channel ESD-protected level translator provide the
level shifting necessary to allow data transfer in a multi-voltage system. Externally applied
voltages, V
CCB
and V
CCA
, set the logic levels on either side of the device. A low-voltage logic
signal present on the V
CCA
side of the device appears as a high-voltage logic signal on the V
CCB
side of the device, and vice-versa. The UM3202Q/3202A/3202H bidirectional level translator
utilizes a transmission-gate based design to allow data translation in either direction (V
CCA
↔V
CCB
)
on any single data line. The UM3202Q/3202A/3202H accepts V
CCA
from +1.65V to +3.6V and
V
CCB
from +2.3V to +5.5V, making it ideal for data transfer between low-voltage ASICs / PLDs
and higher voltage systems.
The UM3202Q/3202A/3202H enters a three-state output mode to reduce supply current when
output enable (OE) is low. The UM3202Q/3202A/3202H is designed so that the OE input circuit
is supplied by V
CCA
. ±15kV ESD protection on the V
CCB
side for greater protection in applications
that route signals externally.
The UM3202Q is a dual level translator available in DFN8 1.70×1.35, the UM3202A is a dual
level translator available in QFN10 1.80×1.40, and the UM3202H is a dual level translator
available in CSP8 1.90×0.90 package.
