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 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.
