UM3204Q

Overview

The UM3204Q is a 4-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It provides level shifting to enable data transfer in multi-voltage systems by utilizing a transmission-gate based design that allows data translation in either direction on any single data line. The device accepts VCCA from +1.65V to +3.6V and VCCB from +2.3V to +5.5V, making it suitable for connecting low-voltage ASICs or PLDs with higher voltage systems. It features ±15kV ESD protection on the VCCB side and enters a three-state output mode when the output enable (OE) input is low.

Feature Summary

• Bidirectional data translation between low-voltage and high-voltage logic domains using transmission-gate architecture
• High electrostatic discharge protection rated at ±15kV on the VCCB side
• Configurable three-state output mode to minimize supply current consumption

Applications

• Data transfer between low-voltage ASICs and higher voltage systems
• Interfacing PLDs with multi-voltage digital circuits
• Open-drain and push-pull application level shifting

Procurement Notes

Verify the specific suffix Q indicates the DFN8 1.70x1.35 package configuration as documented for the UM3202 series variants. Confirm that the OE input circuit is supplied by VCCA during integration. Ensure external voltages VCCA and VCCB are within the specified ranges of 1.65V-3.6V and 2.3V-5.5V respectively to maintain correct logic level translation functionality.

Selection Notes

Select this component when interfacing 1.65V to 3.6V logic devices with 2.3V to 5.5V systems requiring four independent bidirectional channels. The device is appropriate for designs needing robust ESD protection on external signal routes. Consider the DFN8 package constraints if board space is limited. Verify compatibility with both open-drain and push-pull output structures before implementation.
