UM3202V

Overview

The UM3202V 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 defined by external supply voltages, VCCA and VCCB. 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 and utilizes a transmission-gate based design for bidirectional translation. An output enable (OE) input 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 multi-voltage digital circuits
• Open-drain and push-pull interface bridging

Procurement Notes

Verify the specific suffix 'V' against official Union Semiconductor documentation, as standard datasheets typically list variants such as Q, A, or H. Confirm package type and pinout compatibility with your PCB layout. Ensure voltage ranges match your system requirements before integration.

Selection Notes

Select this component when interfacing logic families with overlapping but distinct voltage thresholds. The bidirectional capability simplifies routing compared to unidirectional translators. Verify that the OE control signal is driven by the lower voltage domain (VCCA) to ensure proper functionality.

Part Context

Union Semiconductor produces mixed-signal integrated circuits for consumer and industrial electronics. The UM3202 series addresses the need for reliable communication between disparate voltage domains in compact embedded designs, supporting both analog and digital signal integrity requirements.

Replacement Considerations

Publicly confirmed substitute part numbers for the UM3202V are not available in the provided source material. Consult manufacturer cross-reference guides for equivalent bidirectional level shifters.
