500mA / 50V Digital transistors
(with built-in resistors)
DTD143EK
 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.
