TXB0108PWR

Translators, Level Shifters Overview

The TXB0108PWR is an 8-bit bidirectional voltage-level translator utilizing two independent configurable power-supply rails. It supports a VCCA range of 1.2V to 3.6V and a VCCB range of 1.65V to 5.5V, ensuring A port voltages do not exceed B port voltages. The device features auto direction sensing, eliminating the need for a direction control pin. It includes Ioff support for partial-power-down mode, preventing current leakage when supplies are off. The component provides ±15-kV ESD protection and operates within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates external control pins by automatically detecting signal flow direction
• Ioff circuit disables outputs during partial-power-down to prevent damage from back-driving
• Dual configurable power rails allow translation between different logic families with varying voltage levels
• High electrostatic discharge protection ensures robustness against human-body and charged-device models

Translators, Level Shifters Applications

• Handset and smartphone interconnects
• Tablet computer system buses
• Desktop PC peripheral interfaces

Translators, Level Shifters Procurement Notes

Verify the specific package suffix 'PWR' corresponds to the TSSOP-20 configuration required for your PCB footprint. Confirm that the manufacturer's datasheet specifications for propagation delay and supply voltage ranges align with your system design constraints before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems requiring bidirectional data transfer without dedicated direction control lines. Ensure the target logic family voltage falls within the specified VCCA and VCCB limits. Verify that the application environment remains within the industrial temperature range and that ESD protection requirements are met by the integrated safeguards.

Translators, Level Shifters Part Context

This part belongs to the Texas Instruments TXB0108 series of voltage-level translators.
