SN74CBTS16211DGVR

Overview

The SN74CBTS16211DGVR is a 24-bit FET bus switch from Texas Instruments, housed in a 56-pin TVSOP package. It operates on a single supply voltage ranging from 4 V to 5.5 V and supports an operating temperature range of -40°C to 85°C. The device provides two independent 12-bit switches or one 24-bit switch with TTL-compatible input and output levels. Key electrical characteristics include a maximum propagation delay of 0.35 ns at 4 V and 0.25 ns at 5 V (with CL = 50 pF). On-state resistance varies between 5 Ω and 20 Ω depending on voltage and current conditions.

Feature Summary

• Integrates Schottky diodes on I/Os to clamp undershoot voltages
• Provides high-speed bus switching with minimal propagation delay
• Configurable as dual 12-bit or single 24-bit bus switch
• Features low on-state resistance for efficient signal connection

Applications

• High-speed data routing applications
• Portable equipment requiring low power consumption
• Systems utilizing TTL-compatible logic levels

Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) before finalizing designs. Confirm that the TVSOP-56 package dimensions and thermal impedance meet specific PCB layout requirements. Ensure all unused control inputs are tied to VCC or GND to maintain proper operation and prevent undefined states during implementation.

Selection Notes

Select this component when a 24-bit widebus solution with Schottky clamping is required. It is suitable for applications needing fast switching speeds under 5V logic environments. Consider the TVSOP package constraints regarding board space and thermal dissipation compared to alternative packages like TSSOP or SSOP.

Part Context

This part belongs to Texas Instruments' Widebus family, designed for high-density data transfer. It serves as a bridge between different logic domains using FET technology. The DGVR suffix specifically denotes the TVSOP package variant with tape and reel packaging, distinguishing it from tube-packed alternatives.

Replacement Considerations

Direct functional equivalents within the same family include SN74CBTS16211DL and SN74CBTS16211DGGR. Verify pin compatibility and package footprint differences when substituting the TVSOP variant with SSOP or TSSOP versions.
