SWRCD1284 Parallel Port Termination Network are enhanced high-speed parallel ports, conforming to the IEEE 1284 standard and are used to provide communications with external devices such as ZIP drives, printers, parallel port SCSI adapters, tape back-up drives, external LAN adapters, scanners, video capture, and other PC peripherals. These advanced ports support bi-directional transfers to 2MB/sec. To effectively support these higher transfer data rates, the IEEE 1284 standard recommends a combined termination, pull-up filter network between the driver/receiver and the cable at both ends of the parallel port interface. In addition, government EMC compatibility requirements impose strict filtering on the parallel port. SEMICONWELL' SWRCD1284 Parallel Port Termination Network addresses all of these requirements by providing a seventeen line, IEEE 1284 compliant network in a thin film integrated circuit. The device provides a complete parallel port termination solution for space critical applications. All I/O pins are ESD protected for contact discharges up to 4KV per the Human Body Model. The output pins of the device have the highest probability of exposure to ESD pulses so they are protected to 8KV, HBM, thereby providing the necessary robustness for the port’s application environment. SEMICONWELL' technology provides high reliability and low cost through manufacturing efficiency. The resistors and capacitors are fabricated using proprietary state-of-the-art thin film technology. SEMICONWELL' solution is silicon-based and has the same reliability characteristics as today’s integrated circuits. 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 1W/sq to 10,000 W/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. |
