Overview
The SN74CBTLV16211DGG is a low-voltage 24-bit FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 2.3 V to 3.6 V and features Schottky diode clamping for transient protection. The device utilizes a 56-pin TSSOP package with a width of 0.240 inches (6.10 mm). It supports an operating temperature range from -40°C to +85°C and is RoHS compliant.
Feature Summary
- Provides bidirectional data transmission across 24 independent channels
- Integrates Schottky diodes to clamp input signals below VCC or above VCC plus one diode drop
- Designed for low-voltage applications with extended temperature stability
Applications
- High-density data bus switching in portable electronics
- Signal routing in mobile communication devices
- Memory interface protection and switching
Procurement Notes
Verify the specific suffix DGG indicates the tape-and-reel or tube packaging configuration as defined by Texas Instruments documentation. Confirm that the component meets current environmental compliance standards such as RoHS 3. Ensure the ordering part number matches the exact package dimensions and pinout required for the target PCB footprint to avoid assembly errors.
Selection Notes
Select this component when a 24-bit wide bus switch is required within a 2.3 V to 3.6 V supply domain. It is suitable for designs needing Schottky clamping without external components. Compare against the SN74CBTS16211 if higher voltage tolerance is needed, or the SN74CBTD16211 for different drive characteristics. Ensure the 56-TSSOP package fits the available board space.
Part Context
This device belongs to the 74CBTLV family of low-voltage bus switches from Texas Instruments. It shares functional similarities with other 24-bit switches like the SN74CBT16211 but is optimized for lower voltage operation. The DGG suffix denotes the specific 56-pin thin-shrink small-outline package variant used in high-density surface-mount assemblies.
Replacement Considerations
SN74CBTS16211DGG offers similar functionality with potentially different voltage handling. SN74CBTD16211DGGR provides comparable switching capabilities within the same package family. Verify electrical parameters and pin compatibility before substituting.
