Key Specifications

The UM3204QS 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 UM3204QS 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 UM3204QS 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 UM3204QS enters a three-state output mode to reduce supply current when output enable (OE) is low. The UM3204QS 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 UM3204QS is a quad level translator available in QFN14 3.5×3.5 package.
