100mA / 50V Digital transistors
(with built-in resistors)
DTC143XM / DTC143XE / DTC143XUA / DTC143XKA
 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 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.
