About this product
The 74LS33 is a quad 2-input positive NOR buffer with open-collector outputs in a 14-pin PDIP package, from the TTL 74LS series. The open-collector outputs allow wired-OR configurations and driving loads from a separate supply. It is designed for operation from 4.75 V to 5.25 V.

Why do I need a pull-up resistor on the 74LS33 outputs?
Open-collector outputs can only pull the line low. To get a logic-high level, connect a pull-up resistor from each output to the supply, commonly in the kilohm range. The exact value is chosen from the datasheet current and speed requirements.
Can the 74LS33 drive an LED or relay coil?
Yes, within its sink-current limit. Connect the load between its supply and the output pin, and add a series resistor for an LED. For relay coils, add a flyback diode, and check the datasheet current limit first.
