Bias Resistor Transistor
PNP Silicon Surface Mount Transistor with Monolithic Bias Resistor Network
• Applications
Inverter, Interface, Driver
• Features
1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit).
2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input. They also have the advantage of almost completely eliminating parasitic effects.
3) Only the on/off conditions need to be set for operation, making the device design easy.
• We declare that the material of product compliance with
RoHS requirements.
