Overview
The SN74CB3Q16244DL is a 16-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-SSOP package with an operating temperature range from -40°C to +85°C. It functions as a bidirectional bus driver controlled by a low-enable input, designed for efficient data routing in low-power digital systems.
Feature Summary
- Provides 16-bit bidirectional data switching capability
- Operates at low supply voltages of 2.5 V and 3.3 V
- Engineered for high-bandwidth signal integrity
Applications
- Low-voltage digital bus interconnects
- High-speed data routing in portable electronics
- System-level signal switching applications
Procurement Notes
Verify the specific suffix 'DL' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets the required voltage levels and environmental specifications for the target design. Cross-reference the part number with official Texas Instruments documentation to validate availability status and any potential obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring 16-channel switching at 2.5 V or 3.3 V. Consider the 48-SSOP package constraints for board space. Evaluate the high-bandwidth performance requirements against the system's signal integrity needs. Confirm that the low-enable control logic aligns with the system's power management strategy.
Part Context
This device belongs to the SN74CB3Q series of low-voltage bus switches. It shares functional similarities with other members like the SN74CB3Q16244DGGR but differs in packaging. The series is characterized by its ability to handle high-frequency signals while maintaining low power consumption, making it suitable for modern compact electronic designs.
Replacement Considerations
The SN74CB3Q16244DGGR is a documented equivalent offering identical electrical characteristics in a TSSOP package. Verify pin-to-pin compatibility and thermal performance differences between the SSOP and TSSOP footprints during substitution.
