General Description
The UM3204 is quad 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 UM3204 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 UM3204 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 UM3204 enters a three-state output mode to reduce supply current when output enable (OE)
is low. The UM3204 is designed so that the OE input circuit is supplied by V
CCA
. ±5kV ESD
protection on the V
CCB
side for greater protection in applications that route signals externally. The
UM3204 is a quad level translator available in CSP12 1.9×1.4, QFN14 3.5×3.5 and TSSOP14
packages.
