Digital transistors (built-in resistors)
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 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.
