(OUTPUT) (INPUT) R2 PIN 2 EMITTER (GROUND) MARKING DIAGRAM This series of digital transistors is designed to replace a single device and its external resistor bias network. The Bias Resistor Transistor (BRT) contains a single transistor with a monolithic bias network consisting of two resistors; a series base resistor and a base− emitter resistor. The BRT eliminates these individual ponents by integrating them into a single device. The use of a BRT can reduce both system cost and board space.
