SN74CBT6800APWR

Overview

The SN74CBT6800APWR is a 10-bit FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 4 V to 5.5 V and supports an operating temperature from -40°C to +85°C. The device features a maximum on-state resistance of 20 Ohms at VCC = 4 V and 15 Ohms at VCC = 4.5 V, with a typical propagation delay of 0.25 ns at VCC = 5 V. It utilizes a TSSOP-24 package.

Feature Summary

• Provides ten bits of high-speed TTL-compatible bus switching with bidirectional data transfer capabilities.
• Precharges the B port to a user-selectable bias voltage to minimize signal distortion during live insertion.
• Features low on-state resistance for near-zero propagation delay connections between ports.

Applications

• High-speed data bus switching applications
• Live insertion systems requiring minimized noise
• Bidirectional data path routing

Procurement Notes

Verify that the specific part number matches the required package type and temperature rating. Confirm RoHS compliance status and lead finish specifications against current ordering information. Ensure all unused control inputs are properly terminated to VCC or GND during operation to maintain device functionality.

Selection Notes

Select this component when a 10-channel bus switch with precharged outputs is required. Consider the TSSOP-24 package constraints and the 4 V to 5.5 V supply voltage range. Evaluate the 0.25 ns propagation delay and 20 Ohm on-resistance against system timing and impedance requirements.

Part Context

This device belongs to the SN74CBT6800A series of 10-bit FET bus switches. It is designed for applications requiring fast switching speeds and minimal signal distortion. The family includes variants with different packaging options such as SOIC, SSOP, and TVSOP, all sharing the same core electrical characteristics.
