SW74F1071MTC is same as Fairchild Semiconductor 74F1071MTC, a 18-bit undershoot/overshoot clamp which is designed to limit bus voltages and also to protect more sensitive devices from electrical overstress due to electrostatic discharge (ESD). The inputs of the device aggressively clamp voltage excursions nominally at 0.5V below and 7V above ground. integrated clamp Schottky diode network available in surface mount package and as known good die KGD is a low power and low noise solution for reducing reflections on high speed data lines. Reflection on high speed data lines leads to undershoot and overshoot disturbances which may result in improper system operation. Resistor terminations used in parallel or in series with the outputs, when used to terminate high speed data lines, can increase power consumption, degrade the high level output and lower noise immunity or increase propagation delays. Schottky diode termination is the best overall solution for applications in which power consumption and noise immunity are critical considerations. Clamp Schottky diode networks provide optimized lead inductance and parasitic capacitive effects (see added ground pins), improved forward voltage and crosstalk attributes, and best termination performance characteristics at high data transmission rates. Schottky diode 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.

SHORT PRODUCT APPLICATION NOTE
SW74F1071MTC is same as Fairchild Semiconductor 74F1071MTC, a 18-bit undershoot/overshoot clamp designed to limit excessive bus voltage and protects sensitive devices from electrical overstress due to electrostatic discharge (ESD). The inputs aggressively clamp voltage excursions nominally at 0.5V below and 7V above ground.

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.
