UM3208

UM3208 8-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Application UM3208 CSP20 General Description The UM3208 is ±15kV 8-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 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. ±15kV ESD protection on the VCCB side for greater protection in applications that route signals externally. The UM3208 is a 8-channel level translator available in 3.0×2.5 CSP20 bump package.
