SN74CBT6800DWR

Overview

The SN74CBT6800DWR is a digital bus switch manufactured by Texas Instruments, housed in a 24-SOIC surface-mount package. It integrates ten independent 1:1 switches within a single integrated circuit. The device operates on a single power supply ranging from 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. This component belongs to the 74CBTS series and is designed for high-speed signal routing applications requiring low on-resistance and minimal propagation delay.

Feature Summary

• Integrates ten independent single-pole single-throw (SPST) switches for efficient signal routing
• Provides low on-resistance characteristics to minimize signal attenuation across the bus
• Features low propagation delay suitable for high-speed data transmission requirements
• Supports flexible bidirectional signal flow control via dedicated control pins

Applications

• High-speed data bus switching in computer systems
• Signal routing in telecommunications equipment
• Memory bus expansion and configuration
• Portable electronic devices requiring compact signal management

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the 24-SOIC package and tape-and-reel packaging format. Confirm the manufacturer part number matches the official Texas Instruments documentation. Check for current production status as legacy components may have discontinuation notices. Ensure RoHS compliance aligns with project requirements. Validate pinout compatibility during schematic capture to prevent design errors.

Selection Notes

Select this component when designing circuits requiring multiple isolated signal paths controlled by a single logic interface. Consider the 24-pin SOIC footprint constraints against available board space. Evaluate the voltage range compatibility with the system's power rails. Assess thermal performance needs based on the ambient operating environment limits defined in the datasheet specifications.

Part Context

This device is part of the Texas Instruments 74CBTS family of bus switches. These components are engineered to replace mechanical relays or discrete transistor switches in modern digital designs. The family emphasizes low power consumption and small form factors, making them ideal for dense printed circuit board layouts where signal integrity and speed are critical parameters.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics before implementing any substitute part numbers. Verify package compatibility to ensure physical fitment without redesigning the PCB layout.
