LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor NPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network LDTC144ELT1G zApplications Inverter, Interface, Driver 3 zFeatures 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. . be achieved. 4) Higher mounting densities can 1 2 SOT–23 1 BASE z We declare that the material of product compliance with RoHS requirements.
