LESHAN RADIO COMPANY, LTD. Digital transistors (built-in resistors) LDTA144EET1 zFeatures 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 negative 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 device design easy. 3 1 2 SC-89 R1 zDevice marking OUT R2 LDTA144EET1=6C GND (+) OUT IN zAbsolute maximum ratings (Ta=25°C) Parameter Symbol GND Value Unit Supply voltage VCC −50 V Input voltage VIN −40~+10 V mA Output current Power dissipation IO −30 IC(Max.) −100 mA Pd 150 mW Junction temperature Tj 150 °C Storage temperature Tstg −55~+150 °C LDTA144EET1-1/3 LESHAN RADIO COMPANY, LTD.
