Overview
The SN74CB3Q3384APWG4 is a 10-channel FET bus switch designed for automotive applications, supporting 2.5-V operation with high bandwidth. It features low ON-state resistance (RON) of typically 3 Ω and supports data I/Os at 0- to 5-V signaling levels across various voltage ranges including 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V. The device operates within a temperature range of -40°C to +125°C and is housed in a 24-pin TSSOP package.
Feature Summary
- High-speed general-purpose FET bus switch architecture
- Supports 0- to 5-V signaling levels for versatile interface compatibility
- Low ON-state resistance for efficient signal transmission
- Automotive-grade reliability with extended temperature range
Applications
- Automotive infotainment systems
- Data bus switching in vehicle networks
- General-purpose signal routing in electronic control units
Procurement Notes
Verify the specific suffix 'PWG4' confirms the TSSOP-24 package and lead-free RoHS compliance as per Texas Instruments documentation. Confirm automotive qualification status if required for your design. Check current availability through authorized distributors as supply chain conditions may vary. Ensure the operating voltage range matches your system requirements before procurement.
Selection Notes
Select this component when a 10-channel bus switch is needed for automotive environments requiring 2.5-V core logic interfacing with 5-V peripherals. The low RON ensures minimal signal degradation. Consider the TSSOP-24 package constraints for PCB layout. Verify that the 0- to 5-V tolerant I/Os meet the voltage levels of connected devices.
Part Context
This part belongs to the SN74CB3Q series, which are automotive-qualified FET bus switches from Texas Instruments. The series is designed for high-speed data transfer in demanding automotive applications. The 'Q' designation indicates automotive qualification, while '3' denotes the specific generation or feature set within the CB family.
Replacement Considerations
Direct replacements include other SN74CB3Q series variants with similar channel counts and package types. Verify pinout compatibility and electrical specifications such as RON and voltage tolerance. Cross-reference with SN74CBT3384C for non-automotive equivalents if automotive qualification is not strictly required.
