Overview
The DS7832W/883B is a quad high-speed bus transceiver manufactured by Rochester Electronics. It features four independent driver and receiver pairs designed for data transmission systems connected via terminated 120-ohm impedance lines. The device utilizes Schmitt trigger inputs to ensure noise immunity. It is housed in a ceramic flatpack package with 16 terminals, suitable for military-grade applications requiring extended temperature operation.
Feature Summary
- Quad configuration providing four independent driver/receiver pairs for bus-oriented data transmission
- Schmitt trigger input characteristics to enhance noise rejection on signal lines
- Designed for use with terminated 120-ohm impedance transmission lines
- Military-grade qualification under MIL-STD-883 Class B standards
Applications
- Bus organized data transmission systems
- Military avionics communication interfaces
- Terminated high-speed digital bus networks
Procurement Notes
Verify the specific manufacturing date code and lot traceability upon order confirmation. Confirm that the delivered units meet the original National Semiconductor specifications and retain MIL-STD-883 Class B screening records. Ensure the ceramic flatpack package integrity matches the required environmental sealing standards for the target application.
Selection Notes
Select this component when a quad bus transceiver with Schmitt trigger inputs is required for 120-ohm terminated systems. The ceramic flatpack package is necessary for high-reliability environments where plastic packages may fail. Verify that the supply voltage and signal levels are compatible with standard TTL logic families before integration into the circuit design.
Part Context
Rochester Electronics re-introduces discontinued semiconductors with full authorization from original manufacturers. This part originates from the National Semiconductor product line, specifically the Am7838/Am8838 family. The manufacturer provides wafer processing and assembly services to maintain production of these critical legacy components beyond their original availability.
Replacement Considerations
The DS7838N is a pin-compatible alternative available from the same manufacturer. Other equivalents include the DS7838J and DS7838M. Verify package dimensions and electrical parameters against the original design requirements before substituting.
