DTB743XE / DTB743XM Transistors -200mA / -30V Low VCE (sat) Digital transistors (with built-in resistors) DTB743XE / DTB743XM zApplications Inverter, Interface, Driver zDimensions (Unit : mm) DTB743XE 0.7 1.6 0.55 0.3 zFeature 1) VCE(sat) is lower than the conventional products. 2) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 3) 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. 4) Only the on / off conditions need to be set for operation, making the device design easy.
