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 (VCCAVCCB) 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.
