| LESHAN RADIO COMPANY, LTD. Digital transistors (built-in resistors) * 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 thinfilm resistors with complete isolation to allow positive biasing of the input. They also have the advantage of almost completely eliminat-ing parasitic effects. 3) Only the on/off conditions need to be set for operation, making device design easy. * Structure PNP digital transistor ( Built-in resistors) * Equivalent circuit (1) 2.9 + 0.2 1.9+ 0.2 0.95+0.95 (2) 2.8+ 0.2 + 0.2 - 0.1 DTA114EKA 1.1 - + 0.2 0.1 0.8 + 0.1 0 ~ 0.1 IN GND(+) IN OUT GND(+) 0.4 + 0.1 - 0.05 0.15 + 0.1 - 0.06 All terminals have same dimensions EIAJ: SC-- 59 * Absolute maximum ratings(Ta=25 C) Parameter symbol V cc limits -50 -40~+10 -50 -100 200 150 -55~+150 unit V V mA mW C C Supply voltage Input voltage Output current Power dissipation Junction temperature Storage temperature V IN IO I C(Max.)
