Digital transistors
●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 isola-
tion to allow negative biasing of the
input. They also have the advan-
tage of almost completely eliminat-
ing parasitic effects.
3)Only the on/off conditions need to
be set for operation, making device
design easy.
