NHi-15341RT Terminals

The NHi-15341RT is a low cost complete Multi-Protocol MIL-STD- Data Bus Interface between a dual redundant bus and a host processor.

The device functions as a programmable Remote Terminal containing a protocol chip, two +5V monolithic transceivers and 16K word SRAM. The unit is available packaged in a 1.1" x 1.1" 69 pin ceramic PGA, or 1.1" x 1.1" 68 pin ceramic quad flatpack. The only external components required are two coupling transformers.

The NHi-15341RT is plug in compatible with the popular NHi-ET full function family and the 4K word remote terminal family with no changes to hardware or software required.
