TXS03121DRLR

Overview

The TXS03121DRLR is a dual bidirectional voltage-level translator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 5.5 V and supports data rates up to 400 Mbps. The device features an ultra-low quiescent current of 8 uA and functions across an extended temperature range from -40°C to +85°C. Packaged in a compact SOT-5X3-6 surface-mount format, it provides automatic direction sensing for seamless signal translation between different logic voltage domains.

Feature Summary

• Dual bidirectional channels enable simultaneous translation between two independent voltage domains without requiring explicit direction control signals.
• Automatic direction sensing dynamically detects the signal flow direction, simplifying circuit design and reducing component count.
• Ultra-low power consumption with an operating supply current of 8 uA ensures minimal energy usage during standby or idle states.

Applications

• Connecting microcontrollers operating at lower voltages to peripherals requiring higher logic levels
• Interfacing memory devices with varying voltage requirements in embedded systems
• Level shifting in mixed-voltage digital communication buses

Procurement Notes

Verify the specific suffix DRLR corresponds to the required tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected package variant matches the PCB footprint specifications exactly. Validate that the operating voltage range aligns with the target system's power rails to prevent functional issues.

Selection Notes

Select this component when dual-channel bidirectional translation is required within a single package. The SOT-5X3-6 package offers space efficiency for dense layouts. Consider the 2.5 V to 5.5 V supply range compatibility with existing system power architectures. Evaluate the 400 Mbps speed capability against the maximum data rate requirements of the connected interfaces.
