Digital transistor (built-in resistor)
DTC125TUA / DTC125TKA / DTC125TSA
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 device design easy.
4) Higher mounting densities can be achieved.
