Overview
The SN74CBTD3861DWG4 is a digital bus switch manufactured by Texas Instruments, belonging to the 74CBTD series. It features a 10-bit configuration with a single 1:1 circuit topology housed in a 24-SOIC package. The device operates on a single power supply ranging from 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. It complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) rating of 1.
Feature Summary
- Provides bidirectional data transmission for ten independent channels within a single integrated circuit.
- Designed for low-voltage applications utilizing a single power supply source.
- Features TTL-compatible logic levels for straightforward interface integration.
Applications
- High-speed data bus switching in computing systems
- Signal routing in portable electronic devices
- Level shifting between different voltage domains
Procurement Notes
Verify the suffix G4 indicates lead-free composition and RoHS3 compliance when sourcing. Confirm the SOIC-24 package dimensions match the target PCB footprint. Ensure the supply voltage remains within the specified 4.5V to 5.5V range during operation to maintain signal integrity and device reliability.
Selection Notes
Select this component for designs requiring ten-channel bus switching with TTL compatibility. Compare against the SN74CBT3861DWR for standard performance or the SN74CBTLV3861 series if lower voltage operation below 4.5V is required. Verify that the 24-SOIC package fits the available board space constraints.
Part Context
This part is a lead-free variant of the SN74CBTD3861DWR within the Texas Instruments CBT family. It shares identical electrical characteristics and pinout configurations with the base model but adheres to stricter environmental standards. The 'G4' suffix specifically denotes the green/RoHS-compliant manufacturing process.
Replacement Considerations
SN74CBTD3861DWR is the direct non-green equivalent. SN74CBT3861DWR offers similar functionality without the D-series specific attributes. SN74CBTLV3861PWR serves as a low-voltage alternative for 2.3V to 3.6V applications.
