Features OUT
1) Built-In Biasing Resistors, R1 = R2 = 22k. IN
IN
GND
2) Built-in bias resistors enable the configuration of GND

an inverter circuit without connecting external DTA124EE DTA124EUB
input resistors (see equivalent circuit). SOT-416 (SC-75A) (SC-85)
3) The bias resistors consist of thin-film resistors UMT3 SMT3

with complete isolation to allow negative biasing OUT OUT
of the input. They also have the advantage of IN IN
completely eliminating parasitic effects. GND
GND
4) Only the on/off conditions need to be set for DTA124EUA DTA124EKA
operation, making the circuit design easy. SOT-323 (SC-70) SOT-346 (SC-59)
5) Complementary NPN Types :DTC124E series
6) Complex transistors :UMA1N/ FMA1A PNP type Inner circuit
7) Lead Free/RoHS Compliant. R1 OUT
IN
