Abstract
A terminator method and apparatus used with a SCSI bus line for removing noise spikes or transients from data and/or control signals received on the bus line include a voltage regulator, a low voltage regulating circuit, a plurality of pull-up termination resistors, and a suppression network. The voltage regulator is responsive to an input termination power supply voltage for generating a regulated output voltage of a predetermined value. The low voltage regulating circuit is responsive to the regulated output voltage for generating a reference voltage. The plurality of pull-up resistors is interconnected between the regulated output voltage and a plurality of data and/or control signal lines coupled to the bus line for generating termination impedances. The suppression network is interconnected between at least one of the plurality of data and/or control signal lines and the reference voltage for removing transients from the data and/or control signals by limiting the range of the upper voltage level and the lower voltage level appearing thereon.
