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.
