General 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, 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 UM3202Q/3202H/3202V bidirectional level translator
utilizes a transmission-gate based design to allow data translation in either direction (VCCAVCCB)
on any single data line. The UM3202Q/3202H/3202V 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 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 VCCB side for greater protection in applications
that route signals 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.
