DDC144NS
DUAL NPN PRE-BIASED TRANSISTOR
General Descriptions
• DDC144NS features discrete dual NPN transistors that
can support continuous maximum current up to 100 mA.
It is suited for applications where the load needs to be
turned on and off using circuits like micro-controllers,
comparators, etc., particularly at a point of load. The
component devices can be used as a part of a circuit or
as a stand alone discrete device.
