TXB0108DQSR

Translators, Level Shifters Overview

The TXB0108DQSR is an eight-channel bidirectional voltage-level translator manufactured by Texas Instruments. It operates with a maximum supply voltage of 5.5 V and supports minimum voltages of 1.2 V or 1.65 V. The device achieves a data rate of 100 Mb/s with a propagation delay of 9.5 ns. It is housed in a SON-20 package, suitable for surface-mount installation, and functions within a temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides bidirectional translation between two independent power domains
• Supports automatic direction detection without explicit control signals
• Features non-inverting logic functionality for signal integrity

Translators, Level Shifters Applications

• Interfacing low-voltage processors with higher-voltage peripherals
• Connecting I2C, SMBus, and other open-drain buses across voltage domains
• Level shifting in portable battery-powered electronic devices

Translators, Level Shifters Procurement Notes

Verify the specific SON-20 package marking and revision level against the manufacturer datasheet before integration. Confirm that the 1.2 V or 1.65 V minimum voltage specification aligns with your target A-side logic requirements. Ensure thermal management meets the -40°C to +85°C operational limits for your intended environment.

Translators, Level Shifters Selection Notes

Select this component when eight parallel channels are required for simultaneous voltage translation. The SON-20 package offers a compact footprint compared to larger TSSOP options. Consider the 9.5 ns propagation delay if timing constraints are critical for high-speed bus communication protocols.

Translators, Level Shifters Part Context

This part belongs to the TXB0108 series of voltage translators from Texas Instruments. It shares core electrical characteristics with variants like the TXB0108DGSR and TXB0108PWR, differing primarily in physical packaging. The series is designed for general-purpose level shifting in mixed-voltage digital systems.

Translators, Level Shifters Replacement Considerations

Direct substitutes include TXB0108DGSR (VSSOP-20) and TXB0108PWR (TSSOP-20). Verify pinout compatibility and thermal performance differences due to distinct package geometries before swapping.
