-100mA / -50V Digital transistors
(with built-in resistors)
DTA123EM / DTA123EE / DTA123EUA / DTA123EKA
zApplications
Inverter, Interface, Driver
zFeatures
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.
zStructure
PNP epitaxial planar silicon transistor (Resistor built-in type)
