A range of dual digital transistors from Toshiba. These devices include built-in biasing resistors and can be directly driven from digital sources. The range includes dual NPN, dual PNP, and NPN+PNP configurations.
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.
