TSCD143K
NPN Digital Transistor
Pin assignment:
1. TR1 Gnd (Emitter)
2. TR1 Input (Base)
3. TR2 Output (Collector)
4. TR2 Gnd (Emitter)
5. TR2 Input (Base)
6. TR1 Output (Collector)
Vcc = 50V
Vin = - 5V ~ +30V
Io = 100mA(max.)
Features
Build-in bias resistor enable the configuration of an
inverter circuit without connecting external input
resistors (see equivalent circuit)
The bias resistors consist of thin-film resistors with
complete isolation to allow negative biasing of the
input. The also have the advantage of almost
completely eliminating parasitic effects.
Only the on/off conditions need to be set for operation,
making device design easy.
