FXL2TD245L10X

Overview

The FXL2TD245L10X is a low-voltage dual-supply 2-bit signal translator manufactured by Fairchild Semiconductor. It supports configurable voltage supplies and signal levels, enabling both uni-directional and bi-directional translation between logic levels ranging from 1.1V to 3.6V. The device features independent control for each bit, allowing flexible configuration of direction and enable states. Outputs remain in a high-impedance 3-state condition until the active VCC level is reached or if either supply drops to ground. It includes power-off protection and non-preferential power-up sequencing capabilities.

Feature Summary

• Configurable dual-voltage-supply translator supporting bidirectional and unidirectional translation between any two logic levels within the 1.1V to 3.6V range
• Independent per-bit direction and output enable control inputs referenced to the VCCA voltage level
• Power-off protection ensures outputs switch to 3-state if either VCC supply reaches ground potential
• Non-preferential power-up sequencing allows either VCCA or VCCB to be powered first without functional conflict

Applications

• Bi-directional interface between different voltage domains such as 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V
• Portable electronic devices requiring space-saving solutions for voltage translation
• Systems with asynchronous bidirectional data buses operating at varying logic levels

Procurement Notes

Verify the specific suffix L10X against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required ESD protection standards, specifically checking HBM and CDM ratings if applicable to the design environment. Confirm that the MicroPak10 footprint matches the PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when designing systems requiring translation between disparate low-voltage logic families. The independent bit control allows for mixed-direction bus architectures. Verify that the target application operates within the specified 1.1V to 3.6V range for both ports. Consider the MicroPak10 package dimensions for space-constrained layouts.

Part Context

This part belongs to the FXL2TD series of low-voltage translators. It is designed to replace multiple discrete components, reducing board space and complexity. The device utilizes Fairchild's MicroPak technology for compact packaging. It serves as a bridge for communication between microprocessors, memory, and peripherals operating at different supply voltages.
