LDTC144ELT1G

LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor NPN Silicon Surface Mount Transistor with Monolithic Bias Resistor Network Applications Inverter, Interface, Driver 3 LDTC144ELT1G 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 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. We declare that the material of product compliance with RoHS requirements. 1 BASE 1 2 SOT–23 R1 R2 3 COLLECTOR Absolute maximum ratings (Ta=25°C) Parameter Supply voltage Input voltage Output current Power dissipation Junction temperature Storage temperature Symbol VCC VI IO IC(Max.)
