SN74CBT3861PWR

Overview

The SN74CBT3861PWR is a low-voltage 10-bit FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 4.5V to 5.5V and features a 24-TSSOP package with a width of 4.40mm. The device supports bidirectional data transmission with TTL-compatible control logic. It functions within an operating temperature range of -40°C to +85°C and includes level shifting capabilities for interfacing between different voltage domains.

Feature Summary

• Provides ten independent bidirectional FET switches for high-speed signal routing
• Supports level shifting between varying voltage domains via integrated circuitry
• Features TTL-compatible control inputs for straightforward interface integration

Applications

• High-speed data bus switching in digital systems
• Level shifting interfaces between 5V and lower voltage logic families
• Portable equipment requiring efficient signal routing

Procurement Notes

Verify the specific suffix PWR indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required package type and environmental specifications for your design.

Selection Notes

Select this component for applications requiring ten-channel bus switching at 5V logic levels. Consider the 24-TSSOP package constraints for PCB layout. Evaluate propagation delay and on-resistance requirements against system speed needs. Compare against other series members if different bit counts or voltage ranges are necessary.

Part Context

This device belongs to the SN74CBT3861 family of low-voltage bus switches. It shares functional similarities with other Texas Instruments logic ICs designed for signal management. The TSSOP-24 package is common across various logic families, facilitating standardized footprint designs in mixed-signal environments.

Replacement Considerations

SN74CBT3861PWRE4 is a verified equivalent variant offering identical electrical characteristics with RoHS-compliant manufacturing processes.
