FXL2T245L10X

Overview

The FXL2T245L10X is a low-voltage, dual-supply, 2-bit signal translator manufactured by Fairchild Semiconductor. It supports configurable voltage translation between logic levels ranging from 1.1 V to 3.6 V. The device features non-preferential power-up sequencing and outputs that remain in 3-state until an active supply level is reached. Packaged in a 10-lead MicroPak measuring 1.6 mm x 2.1 mm, it provides robust ESD protection exceeding 4 kV HBM.

Feature Summary

• Configurable bi-directional interface supporting any two voltage levels within the 1.1 V to 3.6 V range
• Non-preferential power-up sequencing allowing either supply rail to be powered first without functional compromise
• Integrated power-off protection ensuring outputs switch to 3-state if either supply voltage drops to ground

Applications

• Bi-directional voltage translation between 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains
• Low-voltage portable electronic devices requiring compact footprint solutions
• Systems with asynchronous bidirectional data buses needing isolated high-impedance states during power transitions

Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or its successor entity ON Semiconductor. Confirm the package type is the 10-lead MicroPak (1.6 mm x 2.1 mm). Ensure the datasheet specifies the 3-state output behavior and ESD ratings matching JESD22-A114 standards for reliable integration.

Selection Notes

Select this component when designing circuits requiring translation between disparate low-voltage logic families. The dual-supply architecture allows independent A and B port tracking. The MicroPak package offers significant space savings compared to standard SOIC packages, making it suitable for dense PCB layouts in mobile applications.

Part Context

This part belongs to the FXL2T series of signal translators designed for low-voltage applications. It serves as a bridge between different voltage domains, enabling communication between components operating at distinct logic levels while maintaining signal integrity through configurable direction control and tri-state capabilities.

Replacement Considerations

FXL2T245 is a direct functional equivalent within the same product family.
