FXL2T245L10X

Overview

The FXL2T245L10X is a low-voltage, dual-supply, 2-bit signal translator designed for uni-directional and bi-directional voltage translation between two logic levels. It supports translation between voltages as high as 3.6 V to as low as 1.1 V. The A port tracks the VCCA level and the B port tracks the VCCB level, allowing for bi-directional voltage translation over various levels including 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. It features non-preferential power-up sequencing, outputs remaining in 3-state until active VCC is reached, and power-off protection.

Feature Summary

• Bi-directional interface capability between any two voltage levels ranging from 1.1 V to 3.6 V
• Fully configurable inputs that track the respective VCC level
• Non-preferential power-up sequencing allowing either VCC supply to be powered first
• Outputs remain in 3-state until the active VCC level is reached

Applications

• Voltage translation between different logic levels in embedded systems
• Bi-directional data bus interfacing in mixed-voltage environments
• Signal translation in portable electronic devices with varying supply rails

Procurement Notes

Verify the specific package type and compliance status against official onsemi documentation before procurement. Ensure the ordering suffix matches the required tape and reel or tube configuration. Confirm RoHS and halide-free status through the manufacturer's compliance database. Cross-reference the part number with the latest datasheet revision to ensure compatibility with current design specifications.

Selection Notes

Select this component when bi-directional translation is required between logic levels within the 1.1 V to 3.6 V range. Consider its non-preferential power-up sequencing for systems where supply ramp times vary. Evaluate the 10-lead MicroPak package constraints for space-limited designs. Verify ESD protection requirements against system-level standards.

Part Context

The FXL2T245L10X belongs to onsemi's family of low-voltage signal translators. It is part of the broader portfolio of interface solutions designed for mixed-voltage applications. This device complements other voltage translation and bus switching products offered by the manufacturer.
