NTE 4050 buffer and current sourcing capability, datasheet reading woes
In the data sheet it shows Recommended Operating Conditions for VDD from 3 to 18 volts. 

Also shown is the Absolute Maximum Ratings of -0.5 to 20 volts. This means that no damage will result in the range. 

Also assure that pin 1 (VDD) and pin 8 (VSS) are connected to the circuit. VSS is connection for ground.

You might not want to label your collector GND since the emitter of the transistor is connected to ground (GND)
