Overview
The SN74CBT6800DBLE is a 10-bit FET bus switch manufactured by Texas Instruments. It operates with a supply voltage range of 2.7V to 5.5V and features low on-resistance. The device is designed for hot insertion applications, incorporating precharge outputs to manage signal integrity during connection events. It utilizes a 24-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates ten independent FET switches for high-density data routing
- Includes precharge functionality to support safe hot insertion operations
- Provides low on-resistance for efficient signal transmission
Applications
- Hot swap peripheral interfaces
- High-speed data bus switching
- Portable electronic equipment signal routing
Procurement Notes
Verify the specific suffix 'DBLE' against the manufacturer's current product status, as legacy variants may have discontinuation notices. Confirm RoHS compliance documentation matches the exact part marking. Ensure the TSSOP-24 footprint aligns with design constraints. Cross-reference the datasheet revision date to validate electrical characteristics.
Selection Notes
Select this component when designing systems requiring robust hot-swap capabilities for multi-bit buses. The integrated precharge feature distinguishes it from standard bus switches lacking this protection. Verify that the 2.7V to 5.5V supply range covers all system logic levels. Consider the TSSOP-24 package size relative to available board space.
Part Context
This device belongs to the SN74CBT series of bus switches. It shares functional similarities with other 10-bit switches in the family but is distinguished by its specific package configuration and precharge implementation. The CBTS variant offers similar functionality with automotive qualification.
Replacement Considerations
The SN74CBT6800DW serves as a pin-compatible alternative in the SOIC-24 package. The SN74CBTK6800PWR provides a TSSOP-24 option within the same family. Verify electrical parameters and package dimensions before substitution.
