The AN8612NSR is a terminator IC complying with the standard interface standards [SCSI-I/II] for personal computer, work station and various information equipment. Fixed resistor and regulator which are separately provided in conventional ICs are incorporated in single chip for the AN8612NSR. The stand-by function is also built in the AN8612NSR. Moreover, this IC can easily satisfy the maximum terminal capacitance of 25 pF of the SCSI-II standard, because of its small output terminal capacitance. It can support the 10 M byte/s of SCSI-II and 20 M bytes/s of Fast-20.
