Digital transistors (built-in resistors)
DTB143TK
zFeatures
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 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.
