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 BU63147/49 series accepts phasemodulated bipolar data from a MIL-STD-1553 Data Bus and produces .

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 BU63147/49 series accepts phasemodulated bipolar data from a MIL-STD-1553 Data Bus and produces TTL Signal data at its output. 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 receiver’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-STD1553 system.
