Rohm DTA124XKA -100ma / -50v digital transistors (with built-in resistors) Datasheet

-100mA / -50V Digital transistors
(with built-in resistors)
DTA124XM / DTA124XE / DTA124XUA / DTA124XKA
 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.
