NPN Transistors with Monolithic Bias PIN CONNECTIONS
Resistor Network
(3) (2) (1)
This series of digital transistors is designed to replace a single
device and its external resistor bias network. The Bias Resistor R1 R2
Transistor (BRT) contains a single transistor with a monolithic bias Q1
network consisting of two resistors; a series base resistor and a
base-emitter resistor. The BRT eliminates these individual Q2
components by integrating them into a single device. The use of a BRTcan reduce both system cost and board space. R2 R1
