-100mA/-50V Digital transistors(with built-in resistors) DTA044EM / DTA044EEB / DTA044EUB 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 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 the device design easy.
