DTA144EN3
CYStek Product Specification
General Purpose PNP Digital Transistors (Built-in Resistors
)
DTA144EN3
Features
Built-in bias resistors enable the configuration of an inverter circuit without connecting external
input resistors (see equivalent circuit).
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.
Only the on/off conditions need to be set for operation, making device design easy.
Complements the DTC144EN3
