UM3204
4-Bit Bidirectional Voltage-Level Translator for
Open-Drain and Push-Pull Application
UM3204H CSP12 1.9×1.4
UM3204Q QFN14 3.5×3.5
UM3204UE TSSOP14
General Description
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 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 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 CSP12 1.9×1.4, QFN14 3.5×3.5 and TSSOP14
packages.

Note1. Stresses beyond those listed under "absolute maximum ratings" may cause permanent
damage to the device. These are stress ratings only and functional operation of the device
at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended
periods may affect device reliability.
Note2. The value of VCCA and VCCB are provided in the recommended operating conditions table.
