TXB0101DBVR

Translators, Level Shifters Overview

The TXB0101DBVR is a single-channel bidirectional voltage-level translator manufactured by Texas Instruments. It operates with a VCCA supply range of 1.2 V to 3.6 V and a VCCB supply range of 1.65 V to 5.5 V, ensuring VCCA does not exceed VCCB. The device features automatic direction sensing, eliminating the need for a direction control pin. It provides ±15-kV human-body model ESD protection on port B and supports partial-power-down mode via an Ioff circuit. The component is housed in a 6-pin SOT-23 package.

Translators, Level Shifters Feature Summary

• Automatic direction sensing enables seamless bidirectional data transfer without external control signals.
• Supports partial-power-down operation through dedicated Ioff circuitry to minimize leakage current.
• Provides robust electrostatic discharge protection exceeding standard industry requirements on port B.

Translators, Level Shifters Applications

• Interfacing low-voltage logic families with higher-voltage peripherals
• Portable electronics requiring power management during standby modes
• Industrial systems needing high ESD immunity on communication lines

Translators, Level Shifters Procurement Notes

Verify that the VCCA supply voltage remains strictly lower than or equal to VCCB to ensure correct operation. Confirm the specific revision level matches design requirements, as datasheet parameters may evolve. Ensure the PCB footprint aligns with the SOT-23-6 package dimensions. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Translators, Level Shifters Selection Notes

Select this component when a single channel of bidirectional translation is required between dissimilar voltage domains. It is suitable for applications where minimizing pin count is critical due to the absence of a direction control input. Consider the wide operating temperature range and high ESD ratings for harsh environments. Verify that the maximum data rate requirements are met by the internal transmission gate characteristics.
