|ACT7005/7006 Single Package Solution Dual Transceiver, Protocol, Subsystem
· Incorporates Transceivers, Protocol, and System Interface Components into a Single Hybrid Package· Functions as a Remote Terminal or Bus Controller· Interfaces as a Simple Peripheral Unit CIRCUIT TECHNOLOGY www.aeroflex.com· +5V Operation· Provides 16 of Double Buffered RAM Storage for Transmit and Receive Subaddresses· Pin Programmable for or 16-bit Microprocessors· Full Military to +125°C) Temperature Range
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.
