CLAMP SCHOTTKY DIODE NETWORK 12mA, 20 CHANNELS SWDN001-24 FEATURES APPLICATIONS SCHEMATIC Highly effective termination on controlled and uncontrolled line impedances Saves board space and component cost 20 terminating lines/package 40 Schottky diodes per package Reduce overshoots and undershoots on high speed data lines Note: SWDN001 has been improved and is also available as SWDN005 SHORT PRODUCT APPLICATION NOTE Integrated clamp Schottky diode network 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. SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION 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.

All Semiconwell products are available in die form for chip and wire hybrid circuits and multi chip modules applications. Typical delivery for die products is 6 weeks ARO. For Chip Scale Packaged (CSP) devices consult factory for an update on availability of certain products. SCHOTTKY DIODES RESISTORS CAPACITORS Schottky diodes offers basic ESD protection, with low forward voltage and low power dissipation. Diodes are small physically resulting low junction capacitance and low loading capacitance. The bonding pads are 3µm thick, 99.99% electroplated gold with a TiW barrier that withstands 30 min at 400°C in air without loss of adhesion. Silicon nitride dielectric, MNOS capacitors exhibit high stability, low temperature coefficients, low leakage <10nA and high BV>50V.
