This Integrated NPN PNP Bipolar Digital Transistor is designed to replace a discrete solution array of three transistors and their external resistor bias network. BRTs (Bias Resistor Transistors) contain a single transistor with a monolithic bias network consisting of two resistors; a series base resistor and a base-emitter resistor. The BRT technology eliminates these individual components by integrating them into a single device, therefore the integration of three BRTs results in a significant reduction of both system cost and board space.
