The UM3208 is 8-channel ESD-protected level translator provides 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 UM3208 bidirectional level translator utilizes a transmission-gate based design to allow data translation in either direction (VCCA↔VCCB) on any single data line. The UM3208 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 UM3208 enters a three-state output mode to reduce supply current when output enable (OE) is low. The UM3208 is designed so that the OE input circuit is supplied by VCCA. ±6kV ESD protection on the VCCB side for greater protection in applications that route signals externally.
