DTD114GK
Transistors
500mA / 50V Digital transistors (with built-in resistors)
DTD114GK
Applications Inverter, Interface, Driver Feature 1) The built-in bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input, and parasitic effects are almost completely eliminated. 2) Only the on / off conditions need to be set for operation, making the device design easy. 3) Higher mounting densities can be achieved.
