SN74LS38DRE4

Inverter Gates Overview

The SN74LS38DRE4 is a quadruple 2-input positive-NAND buffer manufactured by Texas Instruments within the 74LS logic family. It features open-collector outputs and operates on a single supply voltage ranging from 4.75 V to 5.25 V. The device is housed in a 16-pin SOIC package with surface-mount installation. It supports an operating temperature range of -40°C to +85°C and includes Schottky clamping for high performance.

Inverter Gates Feature Summary

• Quadruple 2-input positive-NAND buffer configuration
• Open-collector output structure
• Schottky clamped inputs for high-speed performance

Inverter Gates Applications

• General-purpose digital logic buffering
• Open-drain interconnect applications
• Driver circuits requiring wired-OR logic capabilities

Inverter Gates Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance status according to current manufacturer documentation. Confirm the SOIC-16 package dimensions and thermal characteristics match the target PCB layout requirements before finalizing procurement specifications.

Inverter Gates Selection Notes

Select this component when open-collector NAND functionality is required within standard 5V logic systems. Ensure external pull-up resistors are incorporated into the design, as the internal circuitry lacks active high-state drive capability due to the open-collector architecture.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74LS series, utilizing Schottky diodes to prevent charge storage and improve switching speeds compared to standard LS logic. The 'DRE4' designation identifies the specific tape-and-reel packaging variant in the narrow SOIC footprint.

Inverter Gates Replacement Considerations

SN74LS38DR is a compatible alternative from the same manufacturer offering identical electrical characteristics and pinout compatibility.
