Digital Transistors, Toshiba
Resistor-equipped bipolar transistors, also known as Digital Transistors or Bias Resistor Transistors, incorporating one or two integrated resistors. A single series input resistor, or a potential divider of two resistors, allows these devices to be directly driven from digital sources. Both single and dual transistor versions are available.
