FXL2T245L10X_F065

Overview

The FXL2T245L10X is a low-voltage, dual-supply, 2-bit signal translator designed for uni-directional and bi-directional voltage translation between logic levels. It supports voltage ranges from 1.1 V to 3.6 V, with Port A tracking VCCA and Port B tracking VCCB. The device features non-preferential power-up sequencing, allowing either supply to power up first. Outputs remain in 3-state until the active VCC level is reached and switch to 3-state if either VCC is at GND. It includes power-off protection and ESD protection exceeding 4 kV HBM and 8 kV HBM I/O to GND.

Feature Summary

• Configurable dual-voltage-supply translator supporting bi-directional interface between any two levels from 1.1 V to 3.6 V
• Fully configurable inputs that track the respective VCC level for flexible system integration
• Non-preferential power-up sequencing allows either VCCA or VCCB to be powered up first without functional compromise
• Outputs automatically enter 3-state mode if either supply voltage drops to ground, ensuring safe isolation

Applications

• Bi-directional voltage translation in portable consumer electronics
• Interface bridging between different logic voltage domains in mobile devices
• System design requiring independent direction control per bit
• Space-constrained applications utilizing MicroPak packaging

Procurement Notes

Verify the specific suffix F065 against official onsemi documentation to confirm tape-and-reel configuration and quantity. Ensure the component matches the standard FXL2T245 electrical specifications. Confirm RoHS compliance status as indicated in the product preview data. Cross-reference the package type with the 10-lead MicroPak specification. Validate the manufacturer source directly from onsemi channels.

Selection Notes

Select this component when designing systems requiring bidirectional translation between widely varying low voltages, such as 1.2 V to 3.3 V. The dual-supply architecture allows independent domain isolation. Consider the MicroPak package for minimal PCB footprint requirements. Ensure input signals are referenced correctly to VCCA. Verify ESD protection requirements meet system standards given the high HBM ratings.

Part Context

The FXL2T245 series represents a family of low-voltage signal translators introduced by Fairchild Semiconductor, now part of onsemi. These devices address the need for flexible voltage level shifting in modern portable electronics where multiple voltage rails coexist. The 2-bit variant offers compact integration compared to discrete solutions, enabling designers to replace multiple single-bit translators with a single package.

Replacement Considerations

Public confirmed substitute part numbers include FXL2T245L10X. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the same dual-supply capability and ESD protection levels.
