SN74CBTK6800DBQR

Overview

The SN74CBTK6800DBQR is a digital bus switch IC manufactured by Texas Instruments. It features a 10-bit FET configuration housed in a 24-pin TSSOP package. The device operates within a supply voltage range of 4 V to 5.5 V, with a maximum operating temperature of +85°C and a minimum of -40°C. Key electrical specifications include a maximum on-resistance of 20 Ohms and a maximum propagation delay of 250 ps. The component is designed for surface-mount installation and complies with RoHS standards.

Feature Summary

• Provides high-bandwidth signal switching capabilities via ten independent FET channels.
• Features precharged outputs to minimize charge injection during switching transitions.
• Supports bidirectional data flow control across the bus lines.

Applications

• High-speed data bus switching in consumer electronics
• Signal routing in industrial control systems
• Interface bridging between different logic voltage domains

Procurement Notes

Verify the specific suffix DBQR against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm that the 4V to 5.5V supply range aligns with the system power architecture before integration.

Selection Notes

Select this component when a 10-channel bus switch with low on-resistance is required. The TSSOP-24 package suits applications with moderate pin count constraints. Verify that the 250 ps propagation delay meets the timing requirements of the specific bus protocol being implemented.
