Overview
The SN74CBTD3861PWRE4 is a digital bus switch IC from Texas Instruments, featuring ten bidirectional FET switches with level shifting capabilities. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 350 ps. The device has a maximum on-resistance of 7 ohms and functions across an operating temperature range of -40°C to +85°C. It is housed in a 24-pin TSSOP package.
Feature Summary
- Integrates ten bidirectional FET bus switches for high-speed signal routing
- Includes built-in level shifting functionality for interface compatibility
- Provides low on-resistance for minimal signal attenuation
- Supports fast switching speeds with low propagation delay
Applications
- High-speed data bus switching applications
- Level translation between different logic voltage domains
- Signal routing in portable and battery-powered devices
- Interface bridging in consumer electronics
Procurement Notes
Verify the complete part number including the E4 suffix to ensure compliance with specific environmental standards. Confirm that the TSSOP-24 package matches your PCB footprint requirements. Check the datasheet for accurate electrical characteristics relative to your operating voltage and temperature conditions before finalizing procurement.
Selection Notes
Select this component when ten independent bidirectional switches are required alongside level shifting features. It is suitable for designs needing low on-resistance and fast switching speeds within a 5V logic environment. Ensure the TSSOP-24 package fits your board layout constraints and that the operating temperature range meets your application's thermal specifications.
Part Context
This part belongs to the SN74CBTD3861 family of digital bus switches. It shares functional similarities with other members like the SN74CBTD3861PWR but includes the E4 suffix indicating specific manufacturing or environmental compliance variations. The device is designed for high-density applications requiring efficient signal management in compact form factors.
Replacement Considerations
The SN74CBTLV3861PWR is listed as a substitute option. Note that this alternative operates at lower voltages (2.3 V to 3.6 V) and may not be compatible with 5V systems without additional circuitry.
