Overview
The SN74CB3Q16210DLR is a 20-bit FET bus switch manufactured by Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 2.3 V to 3.6 V and supports bidirectional data transmission. The device features an enable input that activates the switches when driven low. It is housed in a 48-pin SSOP package and is qualified under AEC-Q100 standards for automotive reliability. The component functions as a high-bandwidth bus switch suitable for interfacing between different voltage domains.
Feature Summary
- Provides 20-bit bidirectional switching capability for low-voltage digital signals
- Features active-low enable control for precise signal path management
- Qualified for automotive applications under AEC-Q100 standards
- Supports operation across a wide industrial temperature range
Applications
- Automotive infotainment system data buses
- Low-voltage memory interface expansion
- Portable electronic device signal routing
- Industrial control board interconnects
Procurement Notes
Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging variant when ordering. Confirm AEC-Q100 qualification requirements align with target automotive or industrial specifications. Ensure the 48-SSOP footprint matches the PCB design constraints. Cross-reference the latest datasheet revision for any pinout or electrical characteristic updates prior to final procurement.
Selection Notes
Select this component for designs requiring high-density 20-bit switching in a compact surface-mount package. The AEC-Q100 qualification makes it suitable for automotive environments where reliability is critical. Consider the 2.3 V to 3.6 V operating range to ensure compatibility with the system's power rails. The bidirectional nature allows flexible signal flow direction control via the single enable pin.
Part Context
This part belongs to the SN74CB3Q series of low-voltage FET bus switches from Texas Instruments. The 'Q' designation indicates automotive qualification, while the '16210' model number specifies the 20-bit configuration. It complements other devices in the family like the SN74CB3T16210, offering enhanced durability for harsh environments without sacrificing switching performance.
Replacement Considerations
The SN74CB3Q16210DLG4 is a lead-free variant of the same functional device. Verify package compatibility between SSOP and alternative footprints if considering non-TI equivalents.
