SN74LS33NS

Inverter Gates Overview

The SN74LS33NS is a quad 2-input positive-NOR buffer manufactured by Texas Instruments. It belongs to the SN54/74LS series and features open-collector outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0°C to +70°C. It is housed in a 14-pin plastic dual-in-line package (PDIP).

Inverter Gates Feature Summary

• Contains four independent 2-input NOR logic gates.
• Features open-collector output configuration for flexible interfacing.

Inverter Gates Applications

• General-purpose digital logic circuits requiring NOR functionality.
• Interface applications utilizing open-collector output characteristics.

Inverter Gates Procurement Notes

Verify the specific suffix 'NS' against official Texas Instruments documentation to confirm the exact package type and material specifications. Ensure compatibility with standard DIP-14 footprints during PCB layout. Confirm RoHS compliance status through current manufacturer datasheets prior to final procurement decisions.

Inverter Gates Selection Notes

Select this component when a quad 2-input NOR gate with open-collector outputs is required. Verify that the LS logic family speed and power consumption meet system requirements. Ensure the 14-pin PDIP package fits the designated mechanical constraints and assembly process capabilities.

Inverter Gates Part Context

This part is a member of the widely used SN54/74LS series of logic integrated circuits. The LS designation indicates Low-power Schottky technology, which offers improved speed-to-power product compared to standard TTL. The SN74LS33 variant specifically provides NOR logic functions with open-collector outputs, distinguishing it from standard push-pull output variants.
