DTC144WUA pdf
100mA / 50V Digital transistors
(with built-in resistors)
DTC144WE / DTC144WUA / DTC144WKA
Applications
Inverter, Interface, Driver
Features
1)Built-in bias resistors enable the configuration of an inverter
circuit without connecting external input resistors.
2)The bias resistors consist of thin-film resistors with complete
isolation to allow negative biasing of the input, and parasitic
effects are almost completely eliminated.
3)Only the on / off conditions need to be set for operation,
making the device design easy.
4)Higher mounting densities can be achieved.
