SN74CBTD1G384DCKR

Overview

The SN74CBTD1G384DCKR is a single-channel, 1:1 bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 4.5V to 5.5V and functions within an industrial temperature range of -40°C to +85°C. The device is housed in a compact SC-70-5 (SOT-353) surface-mount package. This component belongs to the 74CBTD series and is designed for efficient signal routing applications requiring low power consumption and high-speed data transmission capabilities.

Feature Summary

• Provides a single channel for bidirectional data switching between two ports
• Operates with a single power supply voltage source
• Engineered for low-power consumption during active and standby states
• Supports high-speed data transfer rates suitable for modern digital interfaces

Applications

• Portable consumer electronics such as mobile phones and tablets
• Battery-powered devices requiring extended operational life
• High-speed data lines in computing and communication equipment
• Level shifting applications between different voltage domains

Procurement Notes

Verify the specific ordering suffix DCKR to confirm the SC-70-5 package type and tape-and-reel packaging configuration. Ensure compatibility with the target voltage domain of 4.5V to 5.5V. Confirm that the industrial temperature rating meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number against official datasheets to validate pinout and electrical characteristics before integration.

Selection Notes

Select this component when a single-channel bus switch is required for 5V logic systems. The SC-70-5 package offers space savings for dense PCB layouts. Consider the 74CBTD series characteristics for low on-resistance and fast switching speeds. Verify that the input voltage levels align with the system's logic standards. Evaluate thermal performance within the specified operating temperature range.

Part Context

This device is part of the Texas Instruments 74CBTD family of bus switches. These components are designed to replace mechanical relays and other switching solutions in portable applications. The family emphasizes low power consumption and small form factors. The SN74CBTD1G384DCKR specifically addresses needs for single-line signal routing in compact electronic designs.

Replacement Considerations

Check for direct substitutes within the 74CBTD1G series with compatible packages. Verify equivalent electrical parameters such as supply voltage range and propagation delay. Ensure pin-to-pin compatibility if replacing in existing footprints. Consult official substitution guides for validated alternatives.
