FXLA104UMX

Translators, Level Shifters Overview

The FXLA104UMX is a low-voltage dual-supply 4-bit voltage translator manufactured by Fairchild Semiconductor. It features configurable voltage supplies and signal levels, along with 3-state outputs and auto direction sensing capabilities. The device operates within a supply voltage range of 1.65 V to 5.5 V for both ports A and B. It supports bidirectional data transmission with automatic direction detection, eliminating the need for external direction control pins. The component is housed in a UMLP-12 package.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for external direction control pins
• Configurable voltage supplies and signal levels for flexible interface compatibility
• 3-state outputs allow safe connection to multiple buses

Translators, Level Shifters Applications

• Interfacing between different logic families with varying voltage domains
• Portable consumer electronics requiring space-saving level translation
• Battery-powered systems needing low-power operation across voltage ranges

Translators, Level Shifters Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or ON Semiconductor, as corporate acquisitions may affect labeling. Confirm the UMLP-12 package type matches your PCB footprint requirements. Ensure the specific suffix indicates the correct tape and reel configuration for your assembly process. Cross-reference the RoHS compliance status with current regulatory standards for your target market.

Translators, Level Shifters Selection Notes

Select this component when designing interfaces between disparate voltage domains without dedicated direction control signals. The auto-direction feature simplifies board layout by removing control pin dependencies. Consider the UMLP-12 package size constraints against available routing space. Verify that the operating voltage range covers all connected system rails to ensure reliable translation performance.
