Description
The THAT 380G is a large-geometry, 8-transistor, monolithic NPN / PNP array intended for use in multichip modules, hybrids, and chip-on-board applications. The individual devices exhibit both high speed and low noise, and are well-matched between transistors of the same gender. Fabricated in a dielectrically isolated, complementary bipolar process, each transistor is electrically insulated from the others by a layer of insulating oxide (not the reverse-biased PN junctions used in conventional arrays) and exhibit inter-device crosstalk and DC isolation similar to that expected from discrete transistors. The resulting low collector-to-substrate capacitance produces a typical NPN fT of 350MHz (325 MHz for the PNPs). Substrate 93biasing is not required for normal operation, though the substrate should be grounded to optimize speed and minimize crosstalk. 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 available from THAT Corporation. Please contact us directly or through your local distributor for more information.
