DDC144TU
DUAL NPN TRANSISTORS WITH 47K OHM BASE RESISTOR
N
General Description
DDC144TU is best suited for logic switching applications
using control circuits like micro-controllers, comparators,
etc. It features two discrete NPN transistors which can
support maximum continuous current of 100 mA. NPN
transistors can be used as a control and also these can
be biased using higher supply voltages due to the built in
current limiting base resistor of 47 K Ohm. The
component devices can be used as a part of a circuit or
as a stand alone discrete device.
