Транзисторы - биполярные (BJT) - массивы, предварительно смещенные

Pre-biased bipolar transistor arrays incorporate two or more bipolar transistors, along with resistors connected to each transistor in a manner likely to be useful, typically with one resistor between each transistor's emitter and base terminals, and another connected to each transistor's base terminal and a user-accessible pin on the device package.
