SN74LS33NSR

Inverter Gates Overview

The SN74LS33NSR is a quad 2-input positive-NOR buffer manufactured by Texas Instruments. It belongs to the SN74LS series and features open-collector outputs within a 14-pin SOIC package. The device operates with a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 20 ns. It functions reliably across an operating temperature range from 0°C to +70°C, providing four independent NOR logic gates for digital signal processing applications.

Inverter Gates Feature Summary

• Contains four independent 2-input NOR logic gates
• Features open-collector output configuration
• Compatible with standard 5V logic systems

Inverter Gates Applications

• Digital logic circuit design
• Signal buffering in embedded systems
• General-purpose logic gate implementation

Inverter Gates Procurement Notes

Verify the specific suffix 'NSR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 14-SOIC form factor. Confirm RoHS compliance status as indicated in the official documentation before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when a quad NOR gate with open-collector outputs is required in a surface-mount format. It serves as a direct functional replacement for other SN74LS33 variants within the same logic family. Consider the 20 ns propagation delay and 24 mA low-level output current when designing timing-critical or load-driving circuits.

Inverter Gates Part Context

This part is part of the Texas Instruments SN74LS logic family, known for low-power Schottky technology. It provides high-speed operation with reduced power consumption compared to standard TTL. The SN74LS33 variant specifically offers NOR functionality, distinguishing it from NAND or AND gate counterparts in the same series.

Inverter Gates Replacement Considerations

SN74LS33DR is a documented parameter-equivalent substitute from Texas Instruments.
