INTRODUCTION

completely accessible to host

The UT1760A RTS is a monolithic CMOS VLSI solution

totherequirementsofthedual-redundantMIL-STD-1553B

interface as speciﬁed by MIL-STD-1760A. Designed to

reduce cost and space in the mission stores interface, the

RTS integrates the remote terminal logic with a user-

conﬁgured 1K x 16 static RAM. In addition, the RTS has a

ﬂexible subsystem interface to permit use with most

processors or controllers.

❐ Self-test capability, including continuous loop-back

compare

❐ Programmable memory mapping via pointers for

efﬁcient use of internal memory, including buffering

multiple messages per subaddress

❐ RT-RT Terminal Address Compare

❐ Command word stored with incoming data for

enhanced data management

The RTS provides all protocol, data handling, error

checking, and memory control functions, as well as

comprehensive self-test capabilities. The RTS’s memory
