-100mA / -50V Digital transistors (with built-in resistor) DTA144TM / DTA144TE / DTA144TUA / DTA144TKA  Applications Inverter, Interface, Driver  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.

-100mA / -50V Digital transistors (with built-in resistor) DTA144TM / DTA144TE / DTA144TUA / DTA144TKA  Applications Inverter, Interface, Driver  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.  Structure PNP epitaxial planar silicon transistor (Resistor built-in type)  Dimensions (Unit : mm) DTA144TM 1.2 0.32 (3) 0.2 0.8 0.2 1.2 ROHM : VMT3 0.22 (1)(2) 0.4 0.4 0.8 0.13 0.5 DTA144TUA Abbreviated symbol : 96 2.0 0.3 (3) 0.9 0.2 0.7 DTA144TE 1.6 0.3 (3) 0.7 0.55 0.8 1.6 0.1Min.
