DTA124EN3 CYStek Product Specification
PNP Digital Transistors (Built-in Resistors)
DTA124EN3
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 positive 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 DTC124EN3
