SN74CBT3384ADBR

Overview

The SN74CBT3384ADBR is a digital bus switch IC manufactured by Texas Instruments, belonging to the SN74CBT3384A series. It features ten independent FET bus switches arranged in a 5 x 1:1 configuration within a 24-pin SSOP package. The device operates on a single power supply ranging from 4.5 V to 5.5 V, with a maximum operating temperature of +85°C and a minimum of -40°C. Key electrical specifications include a maximum on-resistance of 20 Ohms and a maximum propagation delay of 150 ps. The component draws a maximum supply current of 1.5 mA and is designed for surface-mount installation.

Feature Summary

• Provides ten independent bidirectional data paths for signal routing
• Ensures low signal distortion through minimal propagation delay
• Maintains stable connection integrity via controlled on-resistance

Applications

• High-speed data bus switching in computing systems
• Signal routing in consumer electronics devices
• Interface isolation in industrial control equipment

Procurement Notes

Verify the specific suffix 'ADB' against official Texas Instruments documentation to confirm the exact temperature grade and package variant. Ensure the ordering part number matches the required pinout and RoHS compliance status. Cross-reference the manufacturer's latest datasheet to validate active production status and any recent design changes or lifecycle notices before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring multiple isolated bidirectional channels within a compact footprint. The 5x1:1 architecture suits applications needing simultaneous signal path management without complex external logic. Consider the 24-pin SSOP package constraints for PCB layout density. Verify that the 4.5V to 5.5V supply range aligns with the system's voltage rails and that the thermal performance meets the operational environment requirements.

Part Context

This part belongs to the SN74CBT3384A family of high-speed bus switches. These components are engineered for efficient data transfer in digital systems. The family typically shares similar functional characteristics but may vary in packaging, temperature ratings, or specific electrical tolerances. Understanding the broader family context helps in identifying compatible alternatives or related components for system expansion.

Replacement Considerations

Check for direct substitutes such as the SN74CBT3384CDWR or SN74CBT3384ADWR if pin-compatible alternatives are needed. Verify that any replacement maintains the same 5x1:1 configuration and SSOP-24 package dimensions. Ensure the substitute part supports the required 4.5V to 5.5V operating voltage and meets the necessary propagation delay specifications.
