Dual NPN Bipolar Digital Transistor (BRT)

This series of bipolar digital transistors is designed to replace a single device and its external resistor bias network. The bipolar digital transistor contains a single transistor with a monolithic bias network consisting of two resistors; a series base resistor and a base-emitter resistor. This eliminates these individual components by integrating them into a single device and can reduce both system cost and board space.
