SN74CBTD3384CDWRG4

Overview

The SN74CBTD3384CDWRG4 is a digital bus switch IC manufactured by Texas Instruments. It features ten bits of switching capability within a single package, utilizing five independent 1:1 channels. The device operates on a single power supply ranging from 4.5 V to 5.5 V, with a typical operating voltage of 5 V. Key electrical specifications include a maximum on-resistance of 20 Ohms and a maximum propagation delay of 150 ps. The component supports surface mount installation in a 24-SOIC package (0.295 inch width) and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Provides ten-bit switching capacity through five independent bidirectional channels for efficient data routing.
• Delivers high-speed signal transmission characterized by low propagation delay metrics.
• Maintains stable performance with controlled on-resistance values suitable for precise signal integrity.
• Ensures operational reliability across wide industrial temperature extremes.

Applications

• High-speed data bus switching in computing systems
• Signal routing in telecommunications equipment
• Data transfer interfaces in consumer electronics

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the SOIC-24 package dimensions match your PCB footprint requirements. Ensure the voltage supply aligns with the 4.5 V to 5.5 V operational range. Check for any automotive or specific qualification markings if required for your application environment. Validate the part number against current manufacturer databases to ensure availability and correct revision.

Selection Notes

Select this component when ten-bit bidirectional switching is required within a compact surface-mount form factor. It is appropriate for designs needing low propagation delay and controlled on-resistance at 5 V logic levels. Consider the 24-SOIC package constraints regarding board space and thermal dissipation. Evaluate the -40°C to +85°C temperature range against your environmental conditions. Compare against other 74CBTD series variants if different bit counts or package types are needed.

Part Context

This device belongs to the Texas Instruments 74CBTD3384 family of digital bus switches. These components are designed for high-speed data transfer applications requiring multiple independent switching channels. The family typically offers low on-resistance and fast switching speeds, making them suitable for modern digital systems. The CDWRG4 designation specifies the commercial grade temperature range, SOIC package, and lead-free/RoHS compliant construction.

Replacement Considerations

Direct substitutes may include SN74CBTD3384CDWR or SN74CBTD3384PWRG4, provided pin compatibility and electrical parameters match. Verify that alternative packages maintain the same pinout configuration. Ensure replacement parts meet the same voltage and temperature specifications. Cross-reference datasheets for any differences in on-resistance or propagation delay.
