Overview
The UM3204UE is a 4-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It facilitates data transfer in multi-voltage systems by translating logic levels between two distinct voltage domains. The device utilizes a transmission-gate based design to allow data translation in either direction on any single data line. It accepts VCCA from +1.65V to +3.6V and VC CB from +2.3V to +5.5V, making it suitable for connecting low-voltage ASICs or PLDs with higher voltage systems.
Feature Summary
- Provides bidirectional voltage level translation between low-voltage and high-voltage logic domains
- Supports both open-drain and push-pull application configurations
- Features ±15kV ESD protection on the VC CB side for enhanced signal routing safety
Applications
- Data transfer between low-voltage ASICs and higher voltage systems
- Level shifting in multi-voltage electronic circuits
- Connecting PLDs to higher voltage system components
Procurement Notes
Verify the specific package variant corresponding to the UE suffix against the manufacturer's official datasheet to ensure mechanical compatibility. Confirm that the required voltage domains fall within the specified VCCA (1.65V-3.6V) and VC CB (2.3V-5.5V) ranges for proper operation. Ensure ESD protection requirements align with the ±15kV rating on the VC CB side.
Selection Notes
Select this component when interfacing logic families operating at different voltage levels, specifically where one side operates below 3.6V and the other up to 5.5V. It is appropriate for designs requiring bidirectional data flow without external control signals for directionality. Consider the OE pin functionality if low-power standby modes are required for the system.
Part Context
The UM3204UE belongs to the Union Semiconductor UM3204 series of voltage-level translators. This family includes variants such as UM3202 (2-bit) and UM3208 (8-bit), offering scalable channel counts for different interface widths. The UE designation typically indicates a specific packaging option within this product line, sharing core electrical characteristics with other UM3204 variants like Q and H packages.
