DTB114TK is a digital transistor with built-in resistor. Its features include: 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 positive biasing of the input, and parasitic effects are almost completely eliminated. 3) Only the on / off conditions need to be set for operation, making the device design easy. 4) Higher mounting densities can be achieved.
The DTB1 14TK is a PNP epitaxial planar silicon transistor with an integrated thin‑film bias resistor. It is intended for inverter, interface, and driver circuits, offering high mounting density and simplified design by eliminating external input resistors. Key features include built‑in bias resistors, complete isolation of the resistor network, and a compact SMT package (DTB114TKSMT3). The datasheet lists absolute maximum ratings, external and electrical characteristics, and typical application schematics to aid designers in circuit implementation.
