SN74CBTD16211DGGR

Overview

The SN74CBTD16211DGGR is a dual 12-bit FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 4.5V to 5.5V and features Schottky diode clamping for transient protection. The device is housed in a 56-TSSOP package with a width of 6.10mm. It supports an operating temperature range of -40°C to 85°C and complies with RoHS3 standards. The component is classified under the 74CBTD series and is designed for high-speed data transmission applications requiring low on-resistance.

Feature Summary

• Integrates two independent 12-bit bus switches within a single package
• Includes internal Schottky diodes to clamp transient voltages below VCC or above VDD
• Supports hot insertion without generating excessive current spikes
• Provides bidirectional signal flow between A and B ports controlled by OE pins

Applications

• High-speed data buses such as PCI Express and AGP
• Memory modules and storage interfaces
• Portable equipment requiring low power consumption
• Consumer electronics with multiple voltage domains

Procurement Notes

Verify the specific suffix DGGR corresponds to the tape and reel packaging configuration. Confirm that the RoHS3 compliance status matches current regulatory requirements for your region. Ensure the 56-TSSOP footprint aligns with your PCB design constraints. Check for any recent Product Change Notifications regarding manufacturing site updates.

Selection Notes

Select this component when a dual 12-bit configuration is required for 5V logic systems. Consider the Schottky clamping feature if input signals may exceed the supply voltage. Evaluate the TSSOP package size against available board space. Compare propagation delay specifications against other members of the 74CBT family for timing compatibility.

Part Context

This part belongs to the Texas Instruments 74CBTD series, which focuses on low-voltage, high-speed bus switching. The 'D' suffix typically denotes specific performance characteristics or packaging variations within the broader 74CBT product line. It serves as a replacement for older discrete switching solutions in compact digital designs.

Replacement Considerations

SN74CBT16211CDGGR is listed as a parameter equivalent alternative.
