Description
Designed specifically for use in automatic test equipment where a variable transmitter output level is required, the DDC Model BUS-8559 transceiver is a complete transmitter and receiver conforming to MIL standards 1553A and 1553B.
Features
- coupled to the data bus with the specified transformer.
- , and isolated (on the data side) with two 55 Ω fault isolation resistors, and loaded with two 70 Ω terminations (plus additional receivers), the data bus signal produced is a nominal 0 to 7.5 V pk-pk when measured at the output side of the 55 Ω resistors. When both DATA and DATA, inputs are held low or high, the transmitter presents a high impedance to the line. An external inhibit input is also provided, which allows the the transmitte.
