AN8612NSB
AN8612NSB is SCSI active terminator manufactured by Panasonic.
Overview
The AN8612NSB is a terminator IC conformed to standard interface specification (SCSI-I/II) for personal puters, workstations and various types of information equipment. So far configured with a fixed resistor and a regulator, it has recently been integrated onto a single chip with built-in standby function. It is easy to satisfy 25 p F of the maximum pin capacitance in SCSI-II specification due to its small output pin capacitance. It can sapport 10 Mbyte/s of SCSI-II and 20 Mbyte/s of FAST-20.
