-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.
