TXB0106IPWRQ1

Translators, Level Shifters Overview

The TXB0106IPWRQ1 is a six-bit bidirectional voltage-level translator designed for low-voltage applications. It utilizes two independent, configurable power rails: VCCA (1.2V to 3.6V) and VCCB (1.65V to 5.5V), enabling translation between various logic levels including 1.2V, 1.8V, 3.3V, and 5V. The device supports data rates up to 100 Mb/s with a propagation delay of 4.5 ns. It features automatic direction sensing, Ioff support for partial power-down protection, and AEC-Q100 qualification for automotive environments.

Translators, Level Shifters Feature Summary

• Automatic direction sensing eliminates the need for external direction control signals
• Ioff circuitry disables outputs during power-down to prevent destructive current backflow
• AEC-Q100 qualified for reliable operation in automotive electronic systems
• VCC isolation ensures high-impedance states if either supply rail drops to ground

Translators, Level Shifters Applications

• Automotive infotainment systems requiring level shifting between microcontrollers and peripherals
• Portable devices connecting 1.2V or 1.8V logic domains to 3.3V or 5V buses
• Industrial controllers interfacing low-voltage sensors with higher-voltage communication interfaces

Translators, Level Shifters Procurement Notes

Verify the Q1 suffix confirms AEC-Q100 automotive qualification status. Confirm the PWR package designation matches the required TSSOP-16 footprint for PCB layout compatibility. Ensure the operating temperature range aligns with specific environmental requirements. Cross-reference the manufacturer part number against official distributor catalogs to confirm authenticity and current production status before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation is required without dedicated direction pins. It is suitable for designs needing robust ESD protection and partial power-down capabilities. Compare propagation delay specifications against system timing budgets. Verify that the VCCA voltage range adequately covers the source logic levels while ensuring VCCB remains higher than VCCA as per operational constraints.

Translators, Level Shifters Part Context

This device belongs to the Texas Instruments TXB0106 family of voltage translators. The IPWRQ1 variant specifically denotes the automotive-grade version packaged in a 16-pin TSSOP. It shares functional similarities with standard commercial variants but includes enhanced reliability testing and qualification standards mandated for automotive electronics applications.

Translators, Level Shifters Replacement Considerations

TXB0106PWR serves as the commercial equivalent without automotive qualification. TXB0106DR offers the same functionality in a SOIC-14 package. TXB0106PW provides the same function in a PW (TSSOP) package. Verify pinout compatibility and electrical specifications before substituting any alternative package or grade.
