TXB0106PWR

Translators, Level Shifters Overview

The TXB0106PWR is a 6-bit bidirectional voltage-level translator featuring auto direction sensing and +/-15-kV ESD protection. It utilizes two independent, configurable power rails: VCCA (1.2 V to 3.6 V) and VCCB (1.65 V to 5.5 V), enabling universal low-voltage translation between nodes such as 1.2 V, 1.8 V, 3.3 V, and 5 V. The device supports data rates up to 100 Mb/s with a propagation delay of 14.2 ns. It operates within a temperature range of -40 °C to +85 °C and is housed in a TSSOP-16 package.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for external direction control signals by automatically detecting signal flow.
• Integrated high ESD protection rated at +/-15 kV on the B port ensures robustness against electrostatic discharge events.
• Supports partial power-down mode via Ioff circuitry to prevent destructive current backflow during power-off states.

Translators, Level Shifters Applications

• Mobile phones and smartphones
• Tablets and portable computing devices
• Desktop computers and peripheral interfaces

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 surface-mount package and standard commercial grade when sourcing. Confirm that the manufacturer is Texas Instruments to ensure compatibility with specified electrical characteristics. Check for RoHS compliance status if required by your manufacturing standards. Ensure the supply chain provides genuine components to maintain the specified ESD protection levels and operational reliability.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic families operating at different voltage domains, specifically where VCCA must not exceed VCCB. It is suitable for applications requiring automatic direction detection without GPIO overhead. Consider the TSSOP-16 footprint constraints and the 1.2 V minimum VCCA requirement. Verify that the target application does not require automotive qualification, which would necessitate the Q1 variant instead.

Translators, Level Shifters Part Context

This part belongs to the TXB0106 family of voltage translators from Texas Instruments. It serves as a non-inverting converter designed for bidirectional data transfer. The PWR suffix indicates the plastic small-outline reduced (TSSOP) package type. It is distinct from the automotive-grade TXB0106-Q1, which holds AEC-Q100 certification. The family shares core functionality but differs in qualification standards and specific ordering suffixes.

Translators, Level Shifters Replacement Considerations

The TXB0106IPWRQ1 is an automotive-qualified alternative within the same functional family. Both parts share identical pinouts and electrical specifications for general operation. However, the IPWRQ1 variant meets AEC-Q100 standards for automotive applications. Ensure that any substitution aligns with the environmental and reliability requirements of the final product design.
