100mA / 50V Digital transistors
(with built-in resistors)
DTC143TM / DTC143TE / DTC143TUA / DTC143TKA
 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 negative 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.
 Structure
PNP epitaxial planar silicon transistor (Resistor built-in type)
