The AM29C833ADMB from Advanced Micro Devices is a single-channel non-inverting transceiver with Open Drain outputs, designed for wired-OR bus applications in 5V systems. Operating from 4.5V to 5.5V, it sources 15mA and sinks 24mA, enabling reliable multi-drop communication. The 24-pin ceramic CDIP package provides hermetic sealing for military and aerospace use, with a temperature range of -55°C to 125°C. Ideal for interrupt lines, fieldbus networks, and redundant avionics systems.

  • Open Drain Outputs: Enables wired-OR logic and multi-drop bus topologies without contention.
  • Wide Temperature Range (-55°C to 125°C): Suitable for military, aerospace, and automotive environments.
  • Hermetic CDIP Package: Provides superior protection against moisture and contaminants.
  • Balanced Drive (15mA/24mA): Ensures reliable signaling with external pull-up resistors.

Wired-OR Interrupt Lines

In multi-processor systems, the Open Drain outputs allow multiple devices to assert a shared interrupt line. The 24mA sink current ensures reliable low-level signaling.

Military Data Acquisition

For defense telemetry, this transceiver handles bidirectional data flow between sensors and controllers. The -55°C to 125°C range covers extreme operational environments.

Industrial Fieldbus Communication

In industrial networks, Open Drain outputs enable multi-drop bus topologies. The 15mA source current drives pull-up resistors for fast rise times.

Avionics Redundant Systems

For flight control redundancy, multiple transceivers can share a bus without conflict. The CDIP package provides hermetic sealing for high-altitude operation.

Automotive Diagnostic Buses

In vehicle diagnostics, Open Drain outputs allow multiple ECUs to communicate on a single line. The wide temperature range suits engine bay conditions.

Space-Grade Communication

For satellite communication systems, the ceramic DIP package withstands radiation and thermal cycling. The transceiver ensures reliable data transfer in orbit.
