TSA144C
PNP Digital Transistor
Pin assignment:
1. Input (Base)
2. Gnd (Emitter)
3. Output (Collector)
Vcc = - 50V
Vin = - 40V ~ +10V
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.
Complements the TSC144C
