DESCRIPTION
The BU-63147/49 transceiver is a com-
plete dual transmitter and receiver pair
conforming fully to MIL-STD-1553A
and 1553B. Features include: mono-
lithic design, +5V power supply voltage,
Harris or Smiths type decoder inter-
face, 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 output.
RX DATA OUT and
These 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 receiver’s
outputs.
The
transmitter
section
accepts
bi-phase TTL signal data at its
TX DATA IN and
inputs
and
produces
phase-modulated
bipolar data at the TX DATA OUT and
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 volt-
age,
and
compliance
with
MIL-STD-1553 simplify engineering
design, making it an excellent choice
for interfacing with any MIL-STD-1553
system.
