TXS4555RUTR

Overview

The TXS4555RUTR is a bidirectional voltage-level translator manufactured by Texas Instruments, designed specifically for SIM card interface applications. It operates with a VCCA supply range of 1.65 V to 3.3 V and a VCCB range of 2.3 V to 5.5 V. The device features one channel with non-inverting tri-state outputs and consumes only 5 uA of quiescent current. It is housed in a compact 12-UQFN (1.7x2 mm) package and supports surface-mount installation. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

Provides bidirectional voltage translation between low-voltage logic domains and higher-voltage interfaces.
Specifically engineered for SIM card interface compatibility and signal integrity.
Features non-inverting tri-state output configuration for flexible bus management.

Applications

SIM card slot interface circuits
Voltage level shifting between 1.65V and 5.5V systems
Portable electronic devices requiring low-power translation

Procurement Notes

Verify the specific suffix 'RUTR' corresponds to the UQFN-12 package and reel packaging format. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the ordering part number matches the exact manufacturer designation to avoid substitution errors during procurement.

Selection Notes

Select this component when interfacing low-voltage controllers with SIM cards or similar peripherals requiring up to 5.5V operation. The single-channel design suits simple interface needs, while the ultra-low standby current benefits battery-powered applications. Verify that the required voltage ranges fall within the specified VCCA and VCCB limits for proper functionality.

Part Context

This part belongs to the Texas Instruments TXS4555 series of voltage-level translators. It is categorized under Logic ICs and specifically serves as a SIM card translator. The device is part of the broader portfolio of logic solutions designed for mixed-voltage system integration.
