Overview
The SN74CBTK6800DGVR is a 10-bit FET bus switch manufactured by Texas Instruments, designed for high-speed digital signal routing. It operates within a supply voltage range of 4 V to 5.5 V, with a typical operating voltage of 5 V. The device features a maximum on-resistance of 20 Ohms and a maximum propagation delay of 250 ps, ensuring low signal distortion. It supports an operating temperature range from -40°C to +85°C and is housed in a 24-pin TVSOP package suitable for surface-mount applications.
Feature Summary
- Provides ten independent bidirectional channels for flexible data bus switching
- Features precharged outputs to support live insertion without signal glitches
- Maintains low and flat on-state resistance for consistent signal integrity
Applications
- High-speed data bus switching in consumer electronics
- Live insertion interfaces requiring glitch-free signal transitions
- Portable devices utilizing 5V tolerant I/O architectures
Procurement Notes
Verify the specific suffix DGVR confirms the TVSOP-24 package and tape-and-reel orientation. Confirm RoHS compliance status through official documentation. Ensure the component matches the exact manufacturer part number to avoid pinout or electrical specification mismatches during integration.
Selection Notes
Select this component when ten independent switching channels are required with minimal signal degradation. The low on-resistance and fast propagation delay make it suitable for bandwidth-sensitive applications. Verify that the 4V to 5.5V supply range aligns with the system power architecture and that the TVSOP package fits the PCB layout constraints.
Part Context
This device belongs to the SN74CBTK6800 series of 10-bit FET bus switches. It shares functional similarities with the SN74CBTS6800 but differs in specific internal characteristics such as on-resistance values. The series is engineered for high-bandwidth data paths up to 500 MHz, targeting applications demanding reliable signal routing in compact form factors.
Replacement Considerations
The SN74CBTK6800PWR serves as a pin-compatible alternative using a TSSOP-24 package instead of TVSOP. Electrical specifications may vary slightly, particularly regarding on-resistance limits. Verify package dimensions and thermal performance before substituting.
