    Abstract: A logic level translator (110) having a fast rising edge at its output for converging ECL logic levels into TTL logic levels includes a switching transistor (Q1) having its base adapted to receive an input logic level signal representative of an ECL signal, the collector of the switching transistor (Q1) being connected to an output node (4). A clamp delay circuit (D1, Q2, Rx, Cx) is interconnected between the collector and the base of the switching transistor (Q1) for inhibiting the switching transistor (Q1) from receiving feedback current to its base so as to cause a faster turn-off, thereby producing a fast rising edge response at the output node (4) during a high-to-low transition of the input logic level signal.

    Abstract: A code conversion system is described for converting a stream of data between first and second data codes. The stream of data containing data packets is recognized to be subject to a data fault condition arising from the collision of data packets. The conversion system comprises means for detecting the fault condition, and means for altering the code conversion of the stream of data between the first and second codes so as to reflect the occurrence of the fault condition in the code converted stream of data.
