| 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 isola-tion 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. * Equivalent circuit 2.9 + 0.2 1.9+ 0.2 0.95+ 0.95 (1) (2) 2.8+ 0.2 + 0.2 - 0.1 DTA123EKA 1.1 + 0.2 - 0.1 IN R1 R2 OUT 0.8 + 0.1 0 ~ 0.1 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 V IN IO I C(Max.)
