Product Description

The UM3202Q/3202H/3202V is ±15kV dual channel ESD-protected level translator provide the level shifting necessary to allow data transfer in a multi-voltage system. Externally applied voltages, VCCBand VCCA, set the logic levels on either side of the device. A low-voltage logic signal present on the VCCAside of the device appears as a high-voltage logic signal on the VCCBside of the device, and vice-versa. The UM3202Q/3202H/3202V bidi-rectional level translator utilizes a transmission-gate -based design to allow data translation in either direction (VCCA?VCCB) on any single data line. The UM3202Q/3202H/3202V accepts VCCAfrom +1.65V to +3.6V and VCCBfrom +2.3V to +5.5V, making it ideal for data transfer between low-voltage ASICs / PLDs and higher voltage systems.

The UM3202Q/3202H/3202V enters a three-state output mode to reduce supply current when output enable (OE) is low. The UM3202Q/3202H/3202V is designed so that the OE input circuit is supplied by VCCA. ±15kV ESD protection on the VCCBside for greater protection in applications that route sig-nals externally.

The UM3202Q/3202H/3202V is a dual level translator available in DFN8 1.70×1.35, CSP8 1.9×0.9 and VSSOP8 packages.
