SN74CBTD3861DWR

Overview

The SN74CBTD3861DWR is a digital bus switch manufactured by Texas Instruments, featuring ten bidirectional data channels in a single circuit configuration. It operates on a single power supply within the voltage range of 4.5V to 5.5V. The device utilizes a 24-pin SOIC package with a width of 7.50mm and supports surface mount installation. It functions as a level-shifting bus switch, designed for high-speed signal transmission with a maximum propagation delay of 350 ps and a maximum on-resistance of 7 ohms. The component is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates ten bidirectional FET bus switches into a single integrated circuit for efficient space utilization.
• Provides automatic level shifting capabilities to facilitate communication between different voltage domains.
• Features low on-resistance to minimize signal attenuation during data transmission.
• Supports high-speed operation suitable for demanding digital interface applications.

Applications

• High-speed data bus switching in computing systems
• Level translation between 5V and 3.3V logic domains
• Portable equipment requiring compact signal routing solutions

Procurement Notes

Verify the specific suffix DWR corresponds to the 24-SOIC package and tape-and-reel packaging format. Confirm RoHS3 compliance status and moisture sensitivity level classification prior to integration. Ensure the design accommodates the specified 4.5V to 5.5V supply voltage constraints. Cross-reference the manufacturer part number against current production lifecycle notices to confirm availability.

Selection Notes

Select this component when ten bidirectional channels are required within a single package footprint. Choose this part for applications necessitating automatic level shifting between 5V and lower voltage logic families. Consider this device for designs prioritizing low on-resistance and moderate propagation delay in a standard SOIC form factor.

Part Context
