TXS0108ERKSR

Overview

The TXS0108ERKSR is an 8-bit bidirectional voltage-level translator manufactured by Texas Instruments. It utilizes two separate configurable power-supply rails, with the A port accepting voltages from 1.4V to 3.6V and the B port accepting voltages from 1.65V to 5.5V. The device supports maximum data rates of 110Mbps in push-pull mode and 1.2Mbps in open-drain mode. It operates within a temperature range of -40°C to 85°C and features integrated pull-up resistors for open-drain applications.

Feature Summary

• Eliminates the need for external direction-control signals through automatic detection of signal flow between ports
• Supports flexible power sequencing as either supply rail can be ramped first without affecting operation
• Provides robust electrostatic discharge protection exceeding standard industry requirements on both ports

Applications

• Handsets
• Smartphones
• Tablets
• Desktop PCs

Procurement Notes

Verify the specific package suffix against official documentation to ensure correct physical dimensions and pinout compatibility. Confirm that the operating voltage constraints are strictly maintained during system design to prevent damage. Ensure proper handling procedures are followed due to the sensitivity of the semiconductor components to environmental factors.

Selection Notes

Select this component when interfacing digital systems requiring translation between low-voltage logic domains and higher-voltage nodes up to 5.5V. The device is suitable for designs needing high-speed data transmission with minimal latency. Consider the thermal characteristics and package size relative to the available board space and cooling requirements of the final assembly.

Part Context

This part belongs to the TXS0108E family of level shifters designed for general-purpose voltage translation. It shares architectural similarities with other devices in the series but offers specific performance metrics tailored for high-speed communication interfaces. The RKS suffix indicates a VQFN package variant optimized for compact surface-mount applications.

Replacement Considerations

Consult official substitution lists for verified alternatives. Ensure any replacement maintains identical voltage ranges and channel counts.
