TXS4558RUKR

Overview

The TXS4558RUKR is a dual voltage-level translator manufactured by Texas Instruments, designed to bridge signal compatibility between systems operating at different logic levels. It operates within a supply voltage range of 1.65 V to 3.3 V and features a propagation delay of 1 ns. The device supports bidirectional data transfer and includes an active-low enable pin for power management control. Packaged in a WQFN-20 form factor suitable for surface-mount assembly, it functions across an industrial temperature range from -40°C to +85°C while maintaining a low quiescent current of 5 µA.

Feature Summary

• Supports bidirectional translation between two independent voltage domains
• Includes an active-low enable pin for flexible power control
• Provides high-speed signal transmission with minimal propagation delay

Applications

• Interfacing low-voltage processors with higher-voltage peripherals
• Mixed-signal system designs requiring level shifting
• Portable electronics managing multiple voltage rails

Procurement Notes

Verify the specific suffix RUKR against official datasheets to confirm the WQFN-20 package and reel packaging configuration. Ensure the component meets RoHS compliance requirements for your region. Confirm moisture sensitivity levels and storage conditions prior to soldering to prevent damage during assembly processes.

Selection Notes

Select this component when interfacing mixed-voltage logic families requiring bidirectional communication. Verify that the target application voltage ranges fall within the specified 1.65 V to 3.3 V limits. Consider the WQFN-20 footprint availability and thermal dissipation requirements for dense PCB layouts.
