BUS-8559
VARIABLE OUTPUT MIL-STD-1553 TRANSCEIVER
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 transmitter output to be removed from the line.. When a logic “1” is applied to the TX INHIBIT input, the transmitter is disabled, and the data inputs are ignored.
