SN74CBTD16211DL

Overview

The SN74CBTD16211DL is a dual 12-bit bus switch manufactured by Texas Instruments, designed for low-voltage applications. It operates on a single power supply ranging from 4.5V to 5.5V and features a 56-pin TSSOP package with a width of 6.10mm. The device supports an operating temperature range of -40°C to 85°C and is RoHS3 compliant. It contains two independent circuits configured as 12 x 1:1 switches, suitable for surface mount installation.

Feature Summary

• Dual 12-bit configuration providing 24 individual signal paths within a single integrated circuit
• Single power supply operation compatible with standard 5V logic systems
• Industrial temperature rating ensuring reliable performance in extreme environments

Applications

• High-speed data routing in computer systems
• Signal switching in industrial control panels
• Bus isolation in telecommunications equipment

Procurement Notes

Verify the specific suffix 'DL' against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 56-TFSOP variant. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential design changes affecting pinout or electrical characteristics.

Selection Notes

Select this component when a high-density solution for 5V bus switching is required. The dual 12-bit architecture reduces board space compared to multiple smaller switches. Verify that the 4.5V to 5.5V supply range aligns with the system's power rails. Consider the 56-pin footprint constraints during layout planning to ensure adequate clearance and thermal management.
