*********************************************************************** * Spice Subcircuits for Package Pins *********************************************************************** * These files are subcircuit spice models for the Fairchild Semiconductor * logic devices. They are intended for use as package * models which will accurately represent the characteristics of the * indicated package pins. * * These model files can be used independently from temperature. * * The terminals of these subcircuits are labelled as follows: * EXT node 1 * INT node 3 * GNDI node 0 * * SPECIAL NOTES: * 1. The EXT node is the node which is used to connect external loads * to the package. The INT node is the node which is used to connect * input or output subcircuits to the package elements. In other * words, this is the bond pad node. * 2. The GNDI node is a ground node which is internal to a package. All * subcircuits which represent internal circuits in a package should * have their GNDI nodes connected together. The GNDI node should NOT * be connected to a ground reference node which is used with * external voltage generators. * 3. The inductors which are labelled as L$2 represent average bond * wire inductances. They are not part of the inductance matrix for * the package lead fingers. *********************************************************************** * *********************************************************************** * 16 PIN SOIC PACKAGE (150 MILS WIDE) -
