Overview
The UM3202Q is a dual-channel bidirectional voltage-level translator designed for open-drain and push-pull applications. It facilitates data transfer in multi-voltage systems by shifting logic levels between two domains. The device accepts VCCA from +1.65V to +3.6V and VCCB from +2.3V to +5.5V. It features ±15kV ESD protection on the VCCB side. The component utilizes a transmission-gate based design for bidirectional translation. An output enable (OE) input, supplied by VCCA, allows entry into three-state mode to reduce supply current.
Feature Summary
- Bidirectional level translation using transmission-gate architecture
- ±15kV ESD protection on the high-voltage side
- Configurable output enable for low-power operation
Applications
- Data transfer between low-voltage ASICs and higher voltage systems
- Level shifting between PLDs and higher voltage systems
- Multi-voltage system interconnects
Procurement Notes
Verify the specific suffix Q against the manufacturer's official datasheet to confirm package dimensions and pinout compatibility. Ensure that the VCCA and VCCB power supply connections match the specified voltage ranges of 1.65V-3.6V and 2.3V-5.5V respectively. Confirm that the OE pin functionality aligns with the required power management strategy for the target application.
Selection Notes
Select this component when interfacing circuits operating at different voltage levels, specifically where one side operates below 3.6V and the other up to 5.5V. The bidirectional nature supports flexible signal routing. Consider the DFN8 package size if space constraints are critical. Verify ESD requirements, as the ±15kV rating on the VCCB side offers robust protection for external signal routes.
Part Context
Union Semiconductor produces the UM3202 series, which includes variants like UM3202A and UM3202H.

FAQ
How does the Output Enable (OE) pin function?
The OE input circuit is supplied by VCCA. When OE is low, the device enters a three-state output mode to reduce supply current.
What is the ESD protection rating?
The device provides ±15kV ESD protection on the VCCB side.
