SN74LS33N

Inverter Gates Overview

The SN74LS33N is a quad 2-input positive-NOR buffer manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and features open-collector outputs. The device supports through-hole mounting in a 14-pin DIP package. It functions within a temperature range of 0°C to +70°C, with a typical propagation delay of 20ns at 5V.

Inverter Gates Feature Summary

• Contains four independent 2-input NOR logic gates
• Features open-collector output configuration for wired-logic applications
• Designed for standard TTL logic levels

Inverter Gates Applications

• Digital logic circuit design
• Wired-AND bus configurations
• Interface buffering between logic families

Inverter Gates Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-14 through-hole package variant. Confirm RoHS compliance status as manufacturing processes evolve. Ensure the supplier provides official datasheets matching the SN74LS33 designation to avoid confusion with similar LS series parts.

Inverter Gates Selection Notes

Select this component when open-collector NOR functionality is required in a through-hole assembly. Verify that the load capacitance and pull-up resistor values are compatible with the specified output current capabilities. Ensure system voltage remains within the 4.75V to 5.25V operating range.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74LS (Low-power Schottky) family, known for improved speed over standard TTL while maintaining low power consumption. The SN74LS33 specifically provides NOR logic with open-collector outputs, distinguishing it from push-pull variants like the SN74LS32.

Inverter Gates Replacement Considerations

SN74LS33DR is a pin-compatible surface-mount alternative.
