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)
packaged in a small 1.9" x 2.1"
hybrid. The device is based upon
two DDC custom ICs, which
includes two monolithic bi-polar low
power transceivers and one CMOS
protocol containing data buffers
and timing control logic. It supports
all 13 mode codes for dual redun-
dant operation, any combinaion 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 BUS-65142 Series
special features. A 14-bit built-in-
test word register stores RTU infor-
mation, and sends it to the Bus
Controller in response to the Mode
Command Transmit Bit Word. The
BUS-65142 Series performs contin-
uous on-line wraparound self-test,
and provides four error flags to the
host CPU. Inputs are provided for
host CPU control of 6 bits of the
RTU Status Word.
Its small hermetic package, -55°C
to +125°C operating temperature
range, and complete RTU operation
make the BUS-65142 ideal for most
MIL-STD-1553 applications requir-
ing hardware or microprocessor
subsystems.
