UM3204Q

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 VCCAfrom +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 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 VCCA. ±5kV ESD protection on the VCCB side for greater protection in applications that route signals externally. The UM3204 is a quad level translator available in 1.9 x 1.4 CSP12 and 3.5 x 3.5 QFN14 package.
