SN74LS38NE4

Inverter Gates Overview

The SN74LS38NE4 is a quadruple 2-input positive-NAND buffer manufactured by Texas Instruments. It features open-collector outputs and belongs to the LS logic series. The device is housed in a 14-pin PDIP package with through-hole mounting. It 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.

Inverter Gates Feature Summary

• Contains four independent 2-input NAND gates
• Outputs are open-collector type requiring external pull-up resistors
• Compatible with standard TTL logic families

Inverter Gates Applications

• Open-drain bus line drivers
• Logic level translation between different voltage domains
• Driving indicator lamps or relays

Inverter Gates Procurement Notes

Verify that the component matches the SN74LS38NE4 designation, specifically confirming the NE4 suffix indicates lead-free (NIPDAU) finish and RoHS compliance. Ensure the package is identified as PDIP-14 for through-hole installation. Confirm the manufacturer is Texas Instruments and check the datasheet revision status for accurate electrical specifications.

Inverter Gates Selection Notes

Select this component when a quad NAND gate with open-collector outputs is required for interfacing with higher voltage loads or bus systems. The LS series offers lower power consumption compared to standard TTL. Verify that the application circuit includes appropriate external pull-up resistors on all output lines to ensure proper high-state logic levels.

Inverter Gates Part Context

This part is part of the SN74LS38 family, which includes variants like SN74LS38N and SN74LS38DR. The NE4 suffix denotes environmental compliance and specific lead finish options. It serves as a digital logic buffer suitable for general-purpose switching applications where wired-OR functionality is needed.

Inverter Gates Replacement Considerations

Direct substitutes include SN74LS38N and SN74LS38DR from Texas Instruments. Cross-manufacturer equivalents such as MC74LS38 or DM74LS38 may be compatible if pinouts and electrical characteristics align.
