CA3094, CA3094A, CA3094B Operating Considerations
"Sink" Output (Terminal "Drive" Output (Terminal CA3094 inherently current power) limited. Therefore, load connected between Terminal Terminal Ground), important connect current limiting resistor between Terminal Terminal (V+) protect transistor under shorted load conditions. Similarly, load connected between Terminal Terminal (V+), current limiting resistor should connected between Terminal Terminal ground. circuit applications where emitter output transistor connected most negative potential system, recommended that current limiting resistor inserted between Terminal supply.
