SCSI DIFFERENTIAL TERMINATOR—RN4
Product Description
The RN-4 is a Small Computer System Interface (SCSI) compliant termination network that provides
the mechanical, electrical, and functional requirements for an input/output bus to connect small
computers with a variety of peripheral devices. The most common application of this bus is to
connect small computers with disk drive (mass storage) units. The RN-4 provides 7 or 9 sets of
three-resistor terminator configuration for the differential-line version of the SCSI bus in just one
package, which saves board space and reduced assembly costs by replacing 21 or 27 discrete
components.
Thin film networks offer significant advantages over conventional thick film processes in terms of
tighter absolute and ratio tolerances, greater stability, lower noise, and Temperature Coefficient of
Resistance (TCR). Furthermore, they offer superior high frequency performance with minimal
parasitic inductance and capacitance. Integrated thin film networks also afford the benefits of board
space savings, reduced assembly costs, and increased reliability with fewer components
