General Description

The CT1999 design incorporates ASIC and five Octal Buffers that accomplish the dual redundant

MIL-STD1553B Remote Terminal and/or Bus Controller Protocol Functions. Buffering has been added to the

most commonly used output signals on the CT1999, minimizing external hardware requirements. The CT1999

connects directly to all ACT Driver/Receiver Units.
