Transistors
Digital transistors (built-in resistor)
DTB123YU / DTB123YK / DTB123YS
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 positive 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.
