General Description
The ACT7005/6 Series provides a complete one package interface between the MIL-STD-1553 bus and all
microprocessor systems. The hybrid provides all data buffers and control registers to function as a Bus
Controller or Remote Terminal. Control of the hybrid by the subsystem is through simple I/O port commands.
Internal hybrid logic removes all critical timing imposed on a typical subsystem, thereby simplifying the
implementation of this interface.
