-100mA / -50V Digital transistors
(with built-in resistors)
DTA124EM / DTA124EE / DTA124EUA / DTA124EKA
Applications
Inverter, Interface, Driver
Features
1)Built-in bias resistors enable the configuration of an inverter
circuit without connecting external input
resistors (see the 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.
