TXB0108DGSR

Translators, Level Shifters Overview

The TXB0108DGSR is an 8-bit bidirectional voltage-level translator manufactured by Texas Instruments. It features two separate configurable power-supply rails: VCCA (1.2V to 3.6V) and VCCB (1.65V to 5.5V). The device supports auto-direction sensing, eliminating the need for a direction control pin. It includes Ioff circuitry to support partial-power-down mode, preventing damaging current backflow when powered down. The component provides ±15kV human-body model ESD protection on the B port and operates within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Auto-direction sensing eliminates the need for external direction control pins
• Ioff circuitry enables safe partial-power-down operation without backflow current
• High electrostatic discharge protection ratings ensure robust signal integrity

Translators, Level Shifters Applications

• Smartphones
• Tablets
• Desktop PCs

Translators, Level Shifters Procurement Notes

Verify the specific package suffix DGSR corresponds to the VSSOP-20 form factor required for your PCB layout. Confirm that the ordering information matches the exact revision level needed for your design. Ensure supply chain documentation aligns with the manufacturer's current production status. Cross-reference the datasheet revision date against your project timeline to account for any potential specification updates or lifecycle changes.

Translators, Level Shifters Selection Notes

Select this component when translating between logic families operating at different voltage levels, such as 1.8V to 3.3V or 3.3V to 5V. It is suitable for applications requiring high-speed data translation up to 100 Mbps. Consider the VSSOP-20 package constraints regarding thermal dissipation and board space. Ensure the OE pin is properly biased to maintain the desired output state during power transitions.

Translators, Level Shifters Part Context

This part belongs to the TXB0108 family of 8-bit bidirectional translators from Texas Instruments. It shares core functionality with other variants in the series but differs in physical packaging. The DGSR suffix specifically denotes the VSSOP-20 package type. This family is designed for universal low-voltage translation across various standard voltage nodes commonly found in digital systems.
