Digital transistors (built-in resistors)
DTD123YK
Applications
Inverter, Interface, Driver
Features
1) Built-in bias resistors enable the configuration of
an inverter circuit without connecting external input resistors
see equivalent circuit).
2) The bias resistors consist of thin-film resistors with complete
isolation to allow negative biasing of the input. They also
3) 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.
