Product Description  

The UM3204QT 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 UM3204QT bidirectional level translator utilizes a transmission-gate based design to allow data translation in either direction (VCCA↔VCCB) on any single data line. The UM3204QT 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.
The UM3204QT enters a three-state output mode to reduce supply current when output enable (OE) is low. The UM3204QT is designed so that the OE input circuit is supplied by VCCA. ±5kV ESD protection on the VCCB side for greater protection in applications that route signals externally. The UM3204QT is a quad level translator available in QFN12 1.7×2.0 package.
