TSCD144C Dual 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 = - 10V ~ +12V Io = 100mA(max.) Features Equivalent Circuit 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. Two TSC144C chips in a SOT-363 package Transistor elements are independent, eliminating interference Complements the TSAD144C Ordering Information Part No. Packing Package TSCD144CCU6 Tape & Reel SOT-363 Note: the build-in resistor value type, option as No. Re (KΩ) R (KΩ) Marking TR 1 47 47 7C TR 2 47 47 Absolute Maximum Rating (Ta = 25 oC unless otherwise noted) Parameter Symbol Limit Unit Supply Voltage Vcc 50 V Input Voltage Vin - 10 ~ +12 V Io 100 mA Output Current DC Pulse 100 Power Dissipation (note) PD 200 Operating Junction Temperature TJ +150 o C - 55 to +150 o C Operating Junction and Storage Temperature Range Note: 1.
