How to use 74LS32
74LS32 or 74LS32N has 12 input output pins for a total of four OR gates. To use the 74LS32 Logic gate IC, just power it using the Vcc and ground pins. The typical operating voltage of the IC is +5V, but it can also be operated in +7V. The output voltage of the IC on the pin Y will be equal to the operating voltage of the IC. As per the OR gate truth table, when either one or both the input of the Gate is high the output will be high. Truth table of OR gate is given as:
