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 thinfilm 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 device design
easy.
