Resistor R4 512 is placed in series between thedriver output terminal 118 and signal path 516.If devices 500 and 502 are boards or other substrates in a system, resistors 506-512 could be discrete resistors placed, as shown, in series between the driver outputs 116 and 118 and board/substrate contacts connected to signal paths 514 and516.If devices 500 and 502 are ICs on a board or other substrate
