SN74CB3Q6800DGVR

Overview

The SN74CB3Q6800DGVR is a 10-bit FET bus switch from Texas Instruments, designed for low-voltage applications operating at 2.5 V or 3.3 V. It features a high-bandwidth data path capable of up to 500 MHz and utilizes a charge pump to ensure low, flat ON-state resistance (Ron) of approximately 9 Ohms. The device offers a propagation delay of 225 ps and includes precharged outputs. It supports 5-V tolerant I/Os regardless of whether the device is powered up or down, making it suitable for mixed-voltage systems requiring efficient signal routing.

Feature Summary

• High-bandwidth data path supporting frequencies up to 500 MHz
• Charge pump technology provides low and flat ON-state resistance
• 5-V tolerant I/Os function with device powered up or down
• Precharged outputs reduce switching noise

Applications

• Mixed-voltage level translation in portable devices
• High-speed data bus switching in consumer electronics
• Signal routing in industrial control systems
• Memory interface buffering in computing hardware

Procurement Notes

Verify the specific suffix DGVR indicates the tape-and-reel packaging format when ordering. Confirm that the 10-bit configuration matches the target circuit design requirements. Ensure voltage levels align with the specified 2.5 V or 3.3 V operational range. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Validate pinout compatibility with existing PCB layouts before finalizing procurement decisions.

Selection Notes

Select this component when high bandwidth and low distortion are critical for signal integrity. The 5-V tolerance feature allows seamless integration between different voltage domains without additional level shifters. Consider the TVSOP-24 package size for space-constrained designs. Evaluate the propagation delay specifications against system timing requirements to ensure adequate performance margins for high-speed data transmission applications.

Part Context

This part belongs to the SN74CB3Q series of FET bus switches, which are optimized for low-voltage, high-speed applications. The CB3Q designation indicates specific electrical characteristics tailored for modern digital systems. Texas Instruments designs this family to replace older logic families with improved power efficiency and signal fidelity. The DGVR suffix specifically denotes the reel-based packaging variant for automated assembly processes.

Replacement Considerations
