Digital transistors (built-in resistors)
!Features
1) Built-in bias resistors enable the configuration of an inverter
circuit without connecting external input resistors (see the
equivalent circuit).
2) The bias resistors consist of thin-film resistors with complete
isolation to allow negative 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
device design easy.
!Structure
NPN digital transistor (with built-in resistors)
! We declare that the material of product compliance with
RoHS requirements.
