SN74CBTD3861PW

Overview

The SN74CBTD3861PW is a digital bus switch manufactured by Texas Instruments, featuring a 10-bit configuration in a 24-pin TSSOP package. It operates within a supply voltage range of 5 V and supports bidirectional data transfer with a maximum propagation delay of 350 ps. The device exhibits a maximum on-resistance of 7 ohms and functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates level shifting capabilities for interfacing between different voltage domains
• Provides low on-resistance for efficient signal transmission
• Supports bidirectional data flow control via a single enable input

Applications

• High-speed data bus switching applications
• Level shifting between 5V and lower voltage logic systems
• Portable equipment requiring low power consumption

Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration into production designs.

Selection Notes

Select this component for designs requiring 10-bit wide bus switching at 5V operation. The integrated level shifter distinguishes it from standard variants like the SN74CBT3861. Ensure the TSSOP-24 footprint aligns with the PCB layout constraints and thermal requirements of the target application.

Part Context

This part belongs to the SN74CBTD3861 series, which extends the standard CBT family by adding level-shifting functionality. It shares the 10-bit architecture with the SN74CBT3861 but targets mixed-voltage environments. The 'PW' designation specifically identifies the plastic small-outline thin package type used in space-constrained electronic assemblies.
