General Description
The UM3202Q/3202A/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, V_CCB and V_CCA, set the logic levels on either side of the device. A low-voltage
logic signal present on the V_CCA side of the device appears as a high-voltage logic signal on the
V_CCB side of the device, and vice-versa. The UM3202Q/3202A/3202H/3202V bidirectional level
translator utilizes a transmission-gate based design to allow data translation in either direction
(V_CCA↔V_CCB) on any single data line. The UM3202Q/3202A/3202H/3202V accepts V_CCA from
+1.65V to +3.6V and V_CCB from +2.3V to +5.5V, making it ideal for data transfer between
low-voltage ASICs / PLDs and higher voltage systems.
The UM3202Q/3202A/3202H/3202V enters a three-state output mode to reduce supply current
when output enable (OE) is low. The UM3202Q/3202A/3202H/3202V is designed so that the OE
input circuit is supplied by V_CCA. ±15kV ESD protection on the V_CCB side for greater protection in
applications that route signals externally.
The UM3202Q/3202A/3202H/3202V is a dual level translator available in DFN8 1.70×1.35,
QFN10 1.8×1.4, CSP8 1.9×0.9 and VSSOP8 packages.
