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 eliminating 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 type) *Equivalent circuit DTA124EKA DTA124ECA IN R1 R2 OUT GND(+) IN OUT GND(+) 2.9 + 0.2 1.9+ 0.2 0.95+0.95 (1) (2) 2.8+ 0.2 + 0.2 - 0.1 1.1 - + 0.2 0.1 2.9 + 0.2 1.9+ 0.2 0.95+ 0.95 (1) 0 ~ 0.1 (2) 2.4+ 0.2 + 0.2 - 0.1 0.95 + 0.2 - 0.1 0.8 + 0.1 0.45 + 0.1 0 ~ 0.1 1.6 (3) 0.3 ~ 0.6 (3) 0.15 + 0.1 - 0.06 1.3 0.2Min + 0.1 - 0.05 0.4 + 0.1 - 0.05 (1) GND (2) IN (3) OUT 0.4 0.15 - + 0.1 0.06 (1) GND (2) IN (3) OUT All terminals have same dimensions All terminals have same dimensions DTA124EKA EIAJ: SC-- 59 DTA124ECA EIAJ: SOT-- 23 * Absolute maximum ratings(Ta=25 C) limits symbol V cc V IN IO I C(Max.)
