SN74CBTD16211DGVR

Overview

The SN74CBTD16211DGVR is a 24-bit FET bus switch with level shifting, manufactured by Texas Instruments. It provides high-speed TTL-compatible bus switching in a 56-TVSOP package. The device operates on a single power supply ranging from 4.5V to 5.5V and supports mixed-mode signal operation on all data I/O ports, allowing 5-V input down to 3.3-V output levels. It features low on-state resistance and tracks VCC for output voltage translation. The component is RoHS compliant, has an operating temperature range of -40°C to 85°C, and carries an MSL rating of 1.

Feature Summary

• Provides 24 bits of high-speed TTL-compatible bus switching
• Supports mixed-mode signal operation across all data I/O ports
• Features output voltage translation that tracks VCC
• Enables 5-V input to 3.3-V output level conversion

Applications

• Mixed-voltage system interconnects
• High-speed data bus routing
• TTL-compatible signal switching

Procurement Notes

Verify the specific suffix 'DGVR' confirms the TVSOP-56 package and tape-and-reel packaging format. Confirm the manufacturer is Texas Instruments and check for RoHS3 compliance status. Ensure the part number matches the exact 24-bit configuration with level shifting capabilities as documented in the official datasheet.

Selection Notes

Select this component when 24-bit parallel data switching with integrated level shifting is required. It is suitable for applications needing TTL compatibility and mixed-mode signal support between 5V and 3.3V domains. The TVSOP-56 package offers a compact surface-mount solution for high-density designs requiring low on-state resistance.

Part Context

This part belongs to the SN74CBTD series of bus switches. It is functionally related to other variants like the SN74CBTD16211DGGR, differing primarily in package type (TVSOP vs TSSOP) and reel configuration. It serves as a digital bus switch IC for managing data paths in mixed-voltage environments.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the SN74CBTD16211DGGR. Verify pinout and electrical specifications match before substitution.
