Abstract:
An apparatus comprising:a bidirectional asynchronous open collector buffer having a pair of signal ports, said buffer comprising a first open collector driver having an input coupled with a first one of the signal ports and having an output coupled with a second one of the signal ports for driving the second one of the ports to a low signal when said low signal is applied to the first one of the ports, and a second open collector driver having an input coupled with the second one of the signal ports and having an output coupled with the first one of the signal ports for driving the first one of the signal ports to said low signal when said low signal is applied to the second one of the ports; anda conductor having a length greater than approximately two inches long coupled with a member of the pair of signal ports of the buffer for transmitting a low signal there through.
