SN74CBT3384DWR

Overview

The SN74CBT3384DWR is a digital bus switch manufactured by Texas Instruments, designed for high-speed data routing applications. It features ten independent FET-based switches arranged in a 10-bit configuration within a single integrated circuit. The device operates on a single power supply ranging from 4.5V to 5.5V, ensuring compatibility with standard 5V logic systems. It is housed in a 24-pin SSOP package, suitable for surface-mount assembly. The component supports an operating temperature range of -40°C to +85°C, providing reliability across industrial and commercial environments.

Feature Summary

• Integrates ten independent field-effect transistor (FET) switches for efficient signal routing
• Provides low on-resistance characteristics to minimize signal attenuation during transmission
• Supports bidirectional data flow between input and output ports without direction control pins

Applications

• High-speed data bus switching in computer and telecommunications equipment
• Signal routing in portable battery-powered devices requiring low power consumption
• Driver and display circuits in consumer electronics

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the 24-SSOP package and tape-and-reel packaging format before ordering. Confirm that the 4.5V to 5.5V supply voltage range aligns with the target system design. Ensure thermal management meets the -40°C to +85°C operational requirements for the intended environment.

Selection Notes

Select this component when a 10-bit wide bus switch is required for 5V logic systems. It is appropriate for designs needing bidirectional signal transfer with minimal propagation delay. Consider the SSOP package constraints regarding board space and pin pitch compared to larger SOIC or smaller QFN alternatives.

Part Context

This part belongs to the SN74CBT series of bus switches, which are optimized for low voltage and high-speed applications. It serves as a solution for managing multiple data lines simultaneously, replacing discrete switching components to save board space and reduce complexity in dense electronic assemblies.

Replacement Considerations

Check for direct substitutes such as the SN74CBTD3384CDBR, which shares similar functional specifications but may differ in package type or manufacturing revision. Verify electrical parameters and pinout compatibility before substituting.
