SN74CBT3861DWR

Overview

The SN74CBT3861DWR is a single-supply bus switch manufactured by Texas Instruments, housed in a 24-SOIC package. It contains ten independent bidirectional switches configured as a 10 x 1:1 circuit. The device operates within a voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +85°C. It is RoHS compliant and classified under the 74CBT series.

Feature Summary

• Provides ten independent bidirectional data paths for signal routing
• Operates on a single power supply source
• Features TTL-compatible control logic

Applications

• Portable equipment requiring low power consumption
• Consumer electronics with limited power budgets
• Computing products utilizing standard logic levels

Procurement Notes

Verify the specific suffix DWR corresponds to the 24-SOIC surface-mount package and tape-and-reel shipping configuration. Confirm RoHS3 compliance status and moisture sensitivity level 1 classification during sourcing. Ensure the component matches the active status indicated in official manufacturer documentation before integration into production designs.

Selection Notes

Select this component when designing systems requiring multiple bidirectional data lines controlled by a single enable signal. The 10-bit width reduces board space compared to using individual switches. Verify that the system voltage remains within the 4.5V to 5.5V range to ensure proper operation and signal integrity across all channels.

Part Context

This part belongs to the Texas Instruments 74CBT series of high-speed bus switches. The series focuses on low power consumption and compatibility with standard logic families. The SN74CBT3861 variant specifically offers ten channels, distinguishing it from lower-channel counterparts in the same family while maintaining similar electrical characteristics and packaging options.

Replacement Considerations

SN74CBTD3861DWR is a documented substitute offering identical functionality and pinout within the same package.
