Overview
The SN74CBTLV16211VR is a low-voltage 24-bit FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 2.3V to 3.6V, making it suitable for portable and battery-powered applications. The device features two independent circuits, each handling 12 bits of data in a 1:1 configuration. It is housed in a 56-pin VQFN package with dimensions of 0.240 inches (6.10mm) width. The component supports an operating temperature range from -40°C to 85°C and is designed for surface-mount installation.
Feature Summary
- Provides low-voltage operation compatible with modern portable electronics
- Integrates 24-bit switching capability within a compact form factor
- Utilizes FET technology for efficient signal routing
Applications
- Portable consumer electronics requiring low-power signal management
- Battery-operated devices needing efficient voltage level translation
- High-density digital systems utilizing compact surface-mount packaging
Procurement Notes
Verify the specific suffix 'VR' against official Texas Instruments documentation to confirm the exact tape-and-reel quantity and moisture sensitivity level. Ensure compatibility with the target PCB footprint for the 56-VQFN package. Confirm that the 2.3V to 3.6V supply range aligns with the system design requirements before procurement.
Selection Notes
Select this component when a high-channel-count bus switch is required for low-voltage logic families. The 56-pin VQFN package offers a space-saving solution for dense layouts. Consider the 2.3V minimum operating voltage to ensure proper functionality within the intended power domain. Verify thermal performance within the specified industrial temperature range.
Part Context
This part belongs to the SN74CBT series of bus switches, which are designed for low-voltage applications. The LV variant specifically targets operations below standard 5V logic levels. It serves as a signal routing component in complex digital systems where multiple data lines need simultaneous control.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as other SN74CBTLV16211 variants with different suffixes. Verify if upgraded versions or cross-manufacturer equivalents meet the 2.3V-3.6V operational window and VQFN package constraints.
