BU-65142 and BUS-65142 SERIES*

MIL-STD-1553 DUAL REDUNDANT

REMOTE TERMINAL HYBRID

DESCRIPTION

The BUS-65142 Series is a com-

plete 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 trans-

ceivers and one CMOS protocol

containing data buffers and timing

control logic. It supports all 13 mode

codes for dual redundant operation,

any combination of which can be ille-

galized.

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 BUS-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 BUS-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

small

hermetic

package,

-55°C to +125°C operating tempera-

ture range, and complete RTU opera-

tion make the BUS-65142 ideal for

most MIL-STD-1553 applications

requiring hardware or microprocessor

subsystems.
