SN74CBTLV3245ADW

Overview

The SN74CBTLV3245ADW is an octal FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and features a maximum on-resistance of 7 Ohms. The device exhibits a maximum propagation delay of 250 ps and draws a maximum power supply current of 20 uA. It supports bidirectional data transfer across eight channels and functions reliably within an operating temperature range of -40°C to +85°C. The component is housed in a 20-pin SOIC package.

Feature Summary

• Octal configuration providing eight independent bidirectional data paths for efficient bus management
• Low on-resistance design ensures minimal signal attenuation and high-speed data integrity
• Ultra-low quiescent current consumption supports energy-efficient system operation
• Robust switching performance with fast propagation delays suitable for high-frequency applications

Applications

• Portable equipment requiring low-voltage bus switching
• Consumer electronics utilizing 3.3 V logic systems
• Computing platforms needing high-speed data routing
• Telecommunications infrastructure components

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint, specifically the SOIC-20 dimensions. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when designing circuits that require low-voltage operation between 2.3 V and 3.6 V. The low on-resistance makes it suitable for maintaining signal quality in high-speed digital buses. Consider the SOIC-20 package constraints for board space limitations. Evaluate the propagation delay specifications against the system's timing requirements to ensure adequate performance margins for the intended application speed.

Part Context

This device belongs to the SN74CBTLV3245A series of octal bus switches from Texas Instruments. It is designed for low-voltage applications, offering high-speed switching capabilities with minimal power consumption. The series provides a reliable solution for managing data flow in complex digital systems where signal integrity and speed are critical parameters for overall system performance.

Replacement Considerations

SN74CBTLV3245ADWR is a verified equivalent variant offered in a tape-and-reel packaging format instead of the tube packaging found in the ADW version. Both parts share identical electrical characteristics and pin configurations, allowing for direct substitution based on manufacturing and assembly requirements.
