The THAT 380G is a large-geometry,
8-transistor, monolithic NPN/PNP array intended for
use in multichip modules, hybrids, and chip-onboard applications. The individual devices exhibit
both high speed and low noise, and are well-matched
between transistors of the same gender. While not guaranteed to meet its datasheet
specifications outside the commercial temperature
range, the transistors on the 380G will typically
operate at much higher temperatures than ordinary
junction-isolated devices with similar packing
density.
Quad transistor arrays in DIP and SO packages
with similar performance characteristics are also …
