FUNCTIONAL DESCRIPTION

The DS21T09 is designed to be a single chip termination subsystem for use in PnP SCSI systems, Figure

1. When embedded on a host bus adapter or motherboard, the DS21T09 can automatically sense the

termination status of the SCSI bus and attach or isolate its resistors as needed to maintain proper bus

termination. External and internal active termination can be provided by the DS21T07.
