DTC144GE / DTA144GUA / DTC144GKA / DTC144GSA
Transistors
Digital transistors (built-in resistor)
DTC144GE / DTC144GUA / DTC144GKA / DTC144GSA
Features
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 device design easy.
3) Higher mounting densities can be achieved.
