SEMICONDUCTOR NETWORKS Ferranti semiconductor networks are arrays of interconnected or isolated semiconductor dice encapsulated in a single multilead package. In addition to a useful range of standard arrays, Ferranti offer a custom-build engineering service to design network package layouts to meet customers own specifications. Networks can be designed to replace directly discrete semiconductor assemblies. STANDARD PRODUCTS SILICON PLANAR DUAL TRANSISTORS A range of dual transistors for differential amplifiers and other applications requiring matched transistors with a high degree of parameter uniformity, encapsulated in multilead TO-5. @ The 2N2060 is also available to British Standards specification BS9300C479 Ratings and Characteristics at 25C ambient temperature (each transistor) Maximum Ratings hre athe = 10mA fz (Min.)
