SN74CBT6800ADGVR

Overview

The SN74CBT6800ADGVR is a 10-bit FET bus switch manufactured by Texas Instruments, housed in a 24-pin TVSOP package. 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 TTL-compatible input levels and provides low on-state resistance, typically ranging from 3 Ω to 20 Ω depending on conditions. Propagation delay is minimal, with a maximum of 0.35 ns at 4 V and 0.25 ns at 5 V. The B port outputs are precharged via a bias voltage (BIASV) to minimize live-insertion noise.

Feature Summary

• Provides ten bits of high-speed bidirectional bus switching with near-zero propagation delay.
• Features precharged outputs that connect the B port to a user-selectable bias voltage to minimize signal distortion during live insertion.

Applications

• High-speed data bus routing
• Live insertion applications requiring minimized noise
• Bidirectional signal path control

Procurement Notes

Verify the specific ordering suffix 'DGVR' corresponds to the TVSOP-24 package and tape-and-reel packaging format. Confirm the active production status and RoHS compliance details directly with Texas Instruments or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component for applications requiring low on-resistance and fast switching speeds within a 4 V to 5.5 V supply range. Ensure the design accommodates the 24-pin TVSOP footprint and utilizes the BIASV pin appropriately to leverage the precharge feature for live-insertion scenarios.

Part Context

This part belongs to the SN74CBT6800A family of 10-bit FET bus switches. It shares functional characteristics with other variants in the series, such as the SN74CBTK6800PWR, but differs in package type and specific electrical parameter tolerances defined by the datasheet.
