ACT3492 Series
General Description
The ACT3492 Series is a monolithic implementation of the MIL-STD-1553B Bus Controller, Remote
Terminal and Passive Monitor functions including dual low power Bus tranceivers. All protocol functions
of MIL-STD-1553B are incorporated and a number of options are included to improve flexibility. These
features include programming of the status word, illegalizing specific commands and an independent loop
back self-test which is initiated by the subsystem. This unit is directly compatible with all microprocessor
interfaces such as the CT1611 and CT1800 produced by Aeroflex Incorporated.
