How does ic 7405 work with pin configuration?

Answer 1

The 7405 is a hex inverter with open collector-outputs, the I/O's is as follow:

Input Inverted output

Pin1=A1 Pin2=Y1

Pin3=A2 Pin4=Y2

Pin5=A3 Pin6=Y3

Pin9=A4 Pin8=Y4

Pin11=A5 Pin10=Y5

Pin13=A6 Pin12=Y6

Power pins

Pin14=Vcc +

Pin 7=GND
