A small dot or circle printed on top of an IC indicates

  • A.Vcc
  • B.Gnd
  • C.Pin 14
  • D.Pin 1

Answer: D

Correct answer: Pin 1

The dot, and the notch beside it, mark pin 1; the pins are then numbered anticlockwise from it when the chip is viewed from above. Power and ground pins differ from one device to another, so no fixed pin can be assumed for them.
