PRN125/PRN155 same as SWRN125 THIN FILM DIFFERENTIAL TERMINATION RESISTOR NETWORKS pin to pin compatible with PRN125/PRN155 manufactured by SEMICONWELL SCSI Termination resistor networks , SCSI terminator resistor networks, Stable resistor network 9 lines/package Saves board space and reduces assembly cost Available in standard 20 pin TSSOP, QSOP, SOIC SCSI termination TTL to ECL translatorPrinters, disk drives and CD-ROMs are connected to host through SCSI (Small Computer System Interface). The signals transmitted through the SCSI cable can generate ringing on the bus. The terminating resistor network reduces unwanted reflections on the transmission line. The resistors used for terminating the transmission lines are noiseless, stable and functional at high frequencies. These products are integrated thin film resistor-networks that are designed to suppress transmission line effects on high-speed data lines. These products are manufactured using advanced thin film technologies including ultra-stable and selfpassivating Tantalum Nitride resistors and gold interconnect metalization to achieve excellent uniformity, perform ance and reliability. In die form, these products are ideal for hybrid and multichip module applications. In packaged form, these products are the best solution where space and weight are a concern.

SHORT PRODUCT APPLICATION NOTE
The SWRN125 is a high performance Integrated Device designed to eliminate trensmission line effects on high-speed lines on a SCSI (Small Computer Systems Interface). SCSI is a bus interface covered by ANSI standard that allows for an input/output bus to connect small computers with a variety of peripheral devices. Proper resistor termination requires a resistor whose value closely matches the characteristic impedance of the transmisision line. Thin film networks offer significant advantage over thick film processes in terms of tighter absolute and ratio tolerances, lower noise, lower Temperature Coefficient of Resistance, greater stability. They offer superior high frequency performance with minimal parasitic inductance and capacitance. Integrated thin film networks also offer the benefits of board space savings, reduced assembly costs, and increased reliability with fewer components.

SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION
Integrated passive networks are manufactured using advanced thin film technologies including ultra -stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film resistor technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1 Ω/sq to 10,000 Ω/sq. All Semiconwell's products are available in die form and as KGD, known good die and are ideal for high reliability hybrid and multi chip module applications. Besides thin film resistors, Semiconwell integrates capacitors, Schottky diodes, Zener diodes and transistors. Integrated passive and active networks are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diodes to provide complete standard and custom RCD solutions. In die form, these products are ideal for hybrid and multi chip module applications. In packaged form, these products are the best solution where space and weight are a concern.
