Use Bourns Networks to:

•

Provide the terminating resistors required for SCSI

implementation.

•

Optimize signal transmission by eliminating overshoot

and ringing.

•

Minimize space and routing problems, and reduce

manufacturing cost per installed resistive function.

•

Increase board yields and reliability by reducing

component count.

Termination Of The SCSI Bus

The Small Computer System Interface follows American

National Standard which provides the mechanical, electrical, and

functional requirements for an input/output bus to connect small

computers with a variety of peripheral devices. The most com-

mon application of this bus is to connect small computers with

disk drive (mass storage) units.

The primary resistor network application in SCSI busses is line

termination. The termination method is specified in ANSI

X3.131-1986 as either a Thevenin equivalent dual terminator
