TXB0101DBVT

Translators, Level Shifters Overview

The TXB0101DBVT is a single-channel bidirectional voltage-level translator manufactured by Texas Instruments. It operates with two separate configurable power-supply rails, supporting VCCA from 1.2 V to 3.6 V and VCCB from 1.65 V to 5.5 V. The device features auto direction sensing and ±15-kV ESD protection on the B port. It supports partial-power-down mode via Ioff circuitry and includes an output-enable (OE) input. The component is housed in a 6-pin SOT-5X3 package and is rated for operation between -40°C and +85°C.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for a dedicated direction control pin
• Supports partial-power-down mode operation through integrated Ioff circuitry
• Provides high electrostatic discharge protection on the B port

Translators, Level Shifters Applications

• Bidirectional translation between low-voltage processors and higher-voltage peripherals
• Interface circuits requiring automatic signal direction detection
• Systems utilizing mixed voltage domains such as 1.2-V, 1.8-V, 3.3-V, and 5-V nodes

Translators, Level Shifters Procurement Notes

Verify the specific suffix DBVT corresponds to the SOT-5X3 package and tape-and-reel configuration. Confirm RoHS compliance and lead-free status against the manufacturer's current datasheet revision. Ensure the ordering part number matches the required operating temperature range and electrical specifications for the target application environment.

Translators, Level Shifters Selection Notes

Select this component when a single channel of bidirectional level shifting is required without external direction control logic. It is suitable for applications where space is limited due to its small footprint. Consider the voltage compatibility between the A and B ports to ensure VCCA does not exceed VCCB during normal operation.

Translators, Level Shifters Part Context

This device belongs to the TXB series of voltage translators from Texas Instruments. It is designed for universal low-voltage bidirectional translation between various standard voltage nodes. The series emphasizes ease of use through auto direction sensing and robust ESD protection, making it common in portable and industrial electronics.

Translators, Level Shifters Replacement Considerations

Check for direct substitutes within the same family, such as TXB0101DRLR or TXB0101DBVR, which share identical functionality but may differ in packaging or reel specifications. Verify that any alternative maintains the same voltage ranges and ESD protection levels.
