SN74CBT6800DBQR

Overview

The SN74CBT6800DBQR is a digital bus switch manufactured by Texas Instruments, featuring ten independent FET-based switches in a single package. It operates within a supply voltage range of 4 V to 5.5 V and supports surface-mount installation in a 24-pin SSOP package. The device exhibits a maximum on-resistance of 20 Ohms and a maximum propagation delay of 250 ps. It functions reliably across an operating temperature range from -40°C to +85°C with a maximum power supply current of 20 uA.

Feature Summary

• Integrates ten independent single-pole single-throw (SPST) FET switches for flexible signal routing
• Provides low on-resistance characteristics suitable for high-speed data transmission applications
• Supports bidirectional data flow between input and output ports

Applications

• High-speed data bus switching in portable electronic devices
• Signal routing in consumer electronics systems
• Data line protection and isolation in industrial control interfaces

Procurement Notes

Verify the specific suffix 'DBQR' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with the latest Texas Instruments product selection guide to avoid obsolete variants or alternative package styles that may differ in pinout or electrical specifications.

Selection Notes

Select this component when designing circuits requiring multiple isolated signal paths with low insertion loss. The 10-bit configuration reduces board space compared to using individual switches. Verify that the system voltage remains within the 4 V to 5.5 V range to ensure proper FET operation. Consider the thermal performance of the SSOP package if multiple switches are activated simultaneously under load conditions.

Part Context

This component belongs to the SN74CBT series of low-voltage bus switches designed for high-speed applications. It serves as a compact solution for managing multiple data lines in space-constrained designs. The technology utilizes FET switches to achieve fast switching speeds and low distortion, making it suitable for modern digital communication protocols requiring precise signal integrity.
