BU-63147 and BU-63149
MIL-STD-1553 DATA BUS
+5V TRANSCEIVER
DESCRIPTION
The BU-63147/49 transceiver is a
complete dual transmitter and
receiver pair conforming fully to
MIL-STD-1553A and 1553B.
Features include: monolithic
design, +5V power supply voltage,
Harris or Smiths type decoder
interface, completely independent
dual redundant operation, and
small size (36-pin DIP). The
receiver section of the BU-
63147/49 series accepts phase-
modulated bipolar data from a
MIL-STD-1553 Data Bus and pro-
duces TTL Signal data at its out-
put.
The RX DATA OUT and RX DATA
OUT outputs represent positive and
negative variations of the input data
signals beyond an internally fixed
threshold level. An external STROBE
input enables or disables the receiv-
er’s outputs.
The transmitter section accepts
bi-phase TTL signal data at its
TX DATA IN and TX DATA IN inputs
and produces phase-modulated
bipolar data at the TX DATA OUT
and TX DATA OUT outputs. The
transmitter’s output voltage level is
typically about 11Vpp. An external
input, INHIBIT, takes priority over the
transmitter inputs and disables the
transmitter when activated with a
logic “1”.
The small size, +5V power supply
voltage, and compliance with
MIL-STD-1553 simplify engineering
design, making it an excellent choice
for interfacing with any MIL-STD-
1553 system.
