SN74CBTD16211DLG4

Overview

The SN74CBTD16211DLG4 is a 12-bit bus switch manufactured by Texas Instruments, belonging to the 74CBTD series. It features two independent circuits configured as 12 x 1:1 switches within a 56-TSSOP package. The device operates on a single power supply ranging from 4.5V to 5.5V and supports an operating temperature range of -40°C to 85°C. It is RoHS3 compliant and classified under ECCN EAR99.

Feature Summary

• Provides dual independent 12-bit bus switching capabilities for signal routing
• Designed for surface-mount installation in compact electronic assemblies
• Operates reliably across extended industrial temperature ranges

Applications

• High-speed data bus isolation in computing systems
• Signal path selection in telecommunications equipment
• Peripheral interface management in industrial control units

Procurement Notes

Verify the specific suffix 'DGGR' or 'DLG4' against the manufacturer's current datasheet to ensure package and tape-and-reel specifications match the design requirements. Confirm that the RoHS3 status and MSL level 1 classification are acceptable for the intended manufacturing process and environmental conditions.

Selection Notes

Select this component when a 12-bit wide bus switch with low on-resistance is required for 5V logic applications. Ensure the system voltage remains within the 4.5V to 5.5V range. Consider the 56-pin TSSOP footprint constraints during PCB layout planning to accommodate the high pin count relative to standard logic packages.

Part Context

This part belongs to the Texas Instruments 74CBT family of FET bus switches. It serves as a variant of the SN74CBTD16211 line, distinguished by its specific packaging and manufacturing lot codes. It complements other devices like the SN74CBTLV16211, which targets lower voltage applications, whereas this model is optimized for standard 5V operation.
