SN74LS38N

Inverter Gates Overview

The SN74LS38N is a quadruple 2-input positive-NAND buffer manufactured by Texas Instruments. It belongs to the 74LS logic family and features open-collector outputs, allowing for flexible interfacing with various load types. The device is housed in a standard 14-pin PDIP package designed for through-hole mounting. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a low-level output current of 8 mA. The component functions as a single-function gate suitable for general digital logic applications.

Inverter Gates Feature Summary

• Features four independent 2-input NAND gates configured as buffers
• Provides open-collector outputs for wired-logic connections
• Compatible with standard TTL logic families

Inverter Gates Applications

• Open-collector bus implementations
• Driver circuits for indicator lamps or relays
• Logic level translation interfaces

Inverter Gates Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature rating. Ensure the procurement channel provides genuine Texas Instruments components to avoid counterfeit risks. Confirm RoHS compliance status if required for specific manufacturing standards. Check for obsolescence notices as legacy LS series parts may have limited production availability.

Inverter Gates Selection Notes

Select this component when open-collector NAND functionality is required for driving external loads beyond standard logic levels. The 74LS series offers a balance of speed and power consumption suitable for moderate-frequency digital systems. Consider the 8 mA sink capability for direct interface with small peripherals without additional buffering stages.

Inverter Gates Part Context

This part is part of the widely adopted 7400-series logic family, specifically the Low-power Schottky (LS) variant. It serves as a fundamental building block in digital circuit design, providing basic logical inversion and buffering capabilities. The SN74LS38N is distinct from standard NAND gates due to its open-collector output structure.

Inverter Gates Replacement Considerations

Equivalent parts include SN74LS38D and SN74LS38NSR. Verify pin compatibility and electrical characteristics before substitution.
