Overview
The TXS4555RGTR is a bidirectional voltage-level translator featuring one circuit and one channel, housed in a 16-VQFN (3x3) package. It operates with VCCA ranging from 1.65 V to 3.3 V and VCCB from 2.3 V to 5.5 V. The device provides tri-state, non-inverting outputs and supports surface-mount installation. It functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Designed specifically for SIM card interface applications
- Provides bidirectional voltage translation between low-voltage and high-voltage domains
- Features tri-state, non-inverting output configuration
Applications
- SIM card interface circuits
- Voltage level translation between 1.65V-3.3V and 2.3V-5.5V systems
- Portable electronic devices requiring low-voltage logic interfacing
Procurement Notes
Verify the specific suffix RGTR corresponds to the 16-VQFN package and tape-and-reel packaging format. Confirm RoHS3 compliance and moisture sensitivity level MSL rating 2 during procurement. Ensure the ordering part number matches the required pinout and electrical specifications for the target application design.
Selection Notes
Select this component when a single-channel bidirectional translator is required for SIM card interfaces. It is suitable for designs needing translation between 1.65V-3.3V A-side and 2.3V-5.5V B-side domains. Consider the 16-VQFN package size for space-constrained PCB layouts requiring surface-mount technology.
Part Context
This part belongs to the Texas Instruments TXS4555 series, which are specialized voltage-level translators. The series includes variants like the TXS4555RUTR in a 12-UQFN package. These devices are categorized under analog mixed-signal ICs and logic level shifters, targeting portable electronics and communication interfaces.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components based on pinout, voltage ranges, and package dimensions before substitution.
