Overview
The SN74CB3Q16210DL is a 20-bit FET bus switch manufactured by Texas Instruments. It operates within a low-voltage range of 2.5 V to 3.3 V and features high-bandwidth signal transmission capabilities. The device is housed in a 48-pin SSOP package and is rated for an operating temperature range from -40°C to +85°C. This component functions as a digital bus switch IC designed for efficient data routing in low-voltage applications.
Feature Summary
- Provides 20-bit parallel switching capability via FET technology
- Supports low-voltage operation at 2.5 V and 3.3 V levels
- Engineered for high-bandwidth signal integrity
Applications
- Low-voltage digital bus switching systems
- High-bandwidth data routing interfaces
- Portable electronic devices requiring 2.5-V/3.3-V power domains
Procurement Notes
Verify the specific suffix 'DL' against the manufacturer's official datasheet to confirm the exact package type and tape/reel specifications. Ensure the component matches the required 48-SSOP form factor and industrial temperature grade. Cross-reference ordering information with Texas Instruments documentation to avoid confusion with similar variants like the DGGR or DLG4 versions.
Selection Notes
Select this component when a 20-bit wide bus switch is required for 2.5-V or 3.3-V logic families. The SSOP-48 package is suitable for space-constrained designs needing multiple parallel channels. Consider the high-bandwidth specification if signal integrity at higher frequencies is critical for the application.
Part Context
This part belongs to the SN74CB3Q16210 family of low-voltage FET bus switches. It is distinct from other TI series such as the SN74CBT or SN74CBTLV, which may offer different bit widths or voltage ranges. The Q-series designation typically indicates automotive qualification standards, though verification with the specific datasheet is recommended.
Replacement Considerations
The SN74CB3Q16210DLR is a reel-packaged variant of the same functional device. The SN74CB3Q16210DLG4 represents the lead-free version of the tube-packaged unit. Verify pin compatibility and package dimensions before substituting.
