SN74CBTD3861DGVR

Overview

The SN74CBTD3861DGVR is a Texas Instruments digital bus switch IC featuring ten bidirectional data channels in a single configuration. It operates on a single power supply ranging from 4.5V to 5.5V and supports an industrial temperature range of -40°C to +85°C. The component utilizes a 24-pin TVSOP surface-mount package with a width of 5.30mm. It is RoHS compliant, classified under EAR99, and has a Moisture Sensitivity Level of 1.

Feature Summary

• Provides ten bidirectional data paths for efficient signal routing
• Integrates level-shifting capabilities for voltage translation between different logic domains
• Features low on-resistance for minimal signal attenuation
• Supports high-speed data transmission with low propagation delay

Applications

• High-speed data bus switching in computing systems
• Level shifting between 3.3V and 5V logic interfaces
• Portable equipment requiring low-power signal management
• Consumer electronics utilizing high-density I/O connections

Procurement Notes

Verify the specific suffix DGVR against the manufacturer's official datasheet to confirm the 24-TVSSOP package and tape-and-reel orientation. Ensure the order matches the exact part number to avoid confusion with similar variants like SN74CBT3861 or SN74CBTD3861DWR. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Selection Notes

Select this component when designing circuits that require ten-channel bidirectional switching with integrated level-shifting functionality. It is suitable for applications needing operation within the 4.5V to 5.5V supply range. Consider the TVSOP package constraints for PCB layout. Compare against the SN74CBT3861 series if level shifting is not required, or other pin-count options if fewer channels are sufficient.

Part Context

This device belongs to the Texas Instruments SN74CBT family of high-speed CMOS bus switches. These components are designed for low-voltage and 3.3V systems, offering superior performance over standard TTL-compatible switches. The SN74CBTD3861 variant specifically adds level-shifting features, distinguishing it from the non-level-shifting SN74CBT3861 models within the same product line.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include SN74CBT3861DGVR and SN74CBT3861PWR. Verify functional compatibility regarding level-shifting requirements, as some equivalents may lack this feature.
