DTB543XE / DTB543XM
Transistors
-500mA / -12V Low V
CE
(sat) Digital transistors
(with built-in resistors)
DTB543XE / DTB543XM
Applications
Inverter, Interface, Driver
Feature
1) V
CE
(sat) is lower than conventional products.
2) Built-in bias resistors enable the configuration of an
inverter circuit without connecting external input
resistors (see equivalent circuit).
3) 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.
4) Only the on / off conditions need to be set for
operation, making the device design easy.
