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, VCCB and VCCA, set
the logic levels on either side of the device. A low-voltage logic signal present on the VCCA side of
the device appears as a high-voltage logic signal on the VCCB 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 (VCCA?VCCB) on any single data line. The UM3204 accepts VCCA
from +1.65V to +3.6V and VCCB from +2.3V to +5.5V, making it ideal for data transfer between
low-voltage ASICs / PLDs and higher voltage systems.
