BUS-8553
MIL-STD-1553 TRANSCEIVER
DESCRIPTION
The BUS-1553 Transceiver is a com-
plete transmitter and receiver which
fully conforming to MIL-STD-1553A
and 1553B. Features of this high reli-
ability transceiver include: Harris
15530 type Encoder/Decoder direct
interface compatibility, ±15 V or +15
and -12 V power supply requirements,
and an internal (factory pre-set)
threshold level.
The transmitter section accepts bipo-
lar TTL signal data at its TX Data and
TX Data input lines and produces a
28 V pk-pk differential signal across a
140 Ω load that is coupled through a
transformer to the TX Data and
TX Data outputs. An external TX
INHIBIT, when activated with a logic
“1” will take the transmitter off-line and
ignore the data inputs
The block diagram, FIGURE 1, illus-
trates the BUS-8553 Transceiver. The
receiver section accepts phase-mod-
ulated bipolar data from a MIL-
STD-553 Data Bus and produces TTL
signal data at outputs: RX Data Out
and RX Data Out. These outputs rep-
resent positive and negative excur-
sions of the input bus signals beyond
a preset threshold level. The receiver
can be taken off-line (outputs dis-
abled) by applying a logic “0” to the
RECEIVER STROBE input.
APPLICATION
The BUS-8553s small size, low
power dissipation, and direct inter-
face compatibility with Harris 15530
type Encoder/Decoder makes it an
excellent choice for any MIL-STD-
1553A or 1553B transceiver applica-
tion. The BUS-8553 comes in a her-
metic 24-pin DDIP package that
measures 1.4 x 0.8 x 0.2 inches.
