BU-65142 series*

MIL-STD-1553 DUAL REDUNDANT

REMOTE TERMINAL HYBRID

DESCRIPTION

The BU-65142 Series is a Hi-Rel

radiation tolerent complete dual

redundant MIL-STD-1553 Remote

Terminal Unit (RTU). The device is

based upon two DDC custom ICs,

which includes two monolithic bi-

polar low power transceivers and

one RiCmos protocol containing

data buffers and timing control logic.

It supports all 13 mode codes for dual

redundant operation, any combina-

tion of which can be illegalized.

Parallel data transfers are accom-

plished with a DMA type handshak-

ing, compatible with most CPU

types. Data transfers to/from mem-

ory are simplified by the latched

command word and word count out-

puts.

Error detection and recovery are

enhanced by BU-65142 Series spe-

cial features. A 14-bit built-in-test

word register stores RTU information,

and sends it to the Bus Controller in

response to the Mode Command

Transmit Bit Word. The BU-65142

Series performs continuous on-line

wraparound self-test, and provides

four error flags to the host CPU.

Inputs are provided for host CPU con-

trol of 6 bits of the RTU Status Word.

Its integrated hermetic package,

-55°C to +125°C operating tempera-

ture range, and complete RTU opera-

tion make the BU-65142 ideal for

MIL-STD-1553 applications requiring

hardware or microprocessor subsys-

tems.
