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.
