LDTA144WWT1G

LESHAN RADIO COMPANY, LTD. Bias Resistor Transistor PNP Silicon Surface Mount Transistor with Monolithic Bias Resistor Network Applications Inverter, Interface, Driver Features 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input. They also have the advantage of almost completely eliminating parasitic effects. 3) Only the on/off conditions need to be set for operation, making the device design easy. We declare that the material of product compliance with RoHS requirements. zAbsolute maximum ratings (Ta=25°C) Parameter Supply voltage Input voltage Output current Power dissipation Symbol VCC VI IO IC(Max.)
