Overview
The DS3885W/883 is a BTL (Balanced Transmission Line) arbitration transceiver manufactured by National Semiconductor. It functions as an inverting single-element transceiver with nine bits per element and features three-state outputs. The component is housed in a 48-CFP package and is designed for high-reliability applications requiring robust signal transmission over balanced lines.
Feature Summary
- Supports BTL arbitration protocols for balanced transmission line communication
- Provides inverting signal functionality with nine-bit data elements
- Features three-state output capability for bus sharing
- Complies with MIL-STD-883 screening requirements for rugged environments
Applications
- Military aerospace systems requiring MIL-STD-883 compliance
- Balanced transmission line interfaces in space-limited rugged packages
- High-reliability industrial control systems using BTL arbitration
Procurement Notes
Verify the manufacturer origin, as National Semiconductor assets are now part of Texas Instruments. Confirm the specific suffix /883 indicates adherence to MIL-STD-883 screening standards. Ensure the package type matches the required 48-CFP form factor for your design integration.
Selection Notes
Select this component when a BTL arbitration transceiver is required for balanced line applications. Consider the inverting nature of the device and its nine-bit element structure. Verify that the three-state output aligns with your system's bus architecture and that the ruggedized packaging meets environmental specifications.
Part Context
This device belongs to the DS3885 family of BTL arbitration transceivers. It is designed for applications demanding high reliability and compliance with military standards. The /883 suffix denotes specific screening processes aligned with MIL-STD-883, distinguishing it from commercial variants.
Replacement Considerations
Check for direct equivalents within the DS3885 series or other BTL transceivers from Texas Instruments. Verify pin compatibility and electrical characteristics before substituting.
