SN74F27DRE4

Overview

The SN74F27DRE4 is a triple 3-input NOR gate integrated circuit manufactured by Texas Instruments. It belongs to the F/FAST logic family, utilizing CMOS technology for high-speed digital switching. The device operates within a supply voltage range of 2V to 6V and supports an operating temperature range of 0°C to 70°C. Packaged in a 14-pin SOIC (Small Outline Integrated Circuit) with a tape-and-reel configuration, it features a maximum propagation delay of 15ns at 5V and a typical clock frequency capability of 70MHz. The component is RoHS compliant and lead-free.

Feature Summary

• Triple 3-input NOR logic function implementation
• High-speed F/FAST series performance characteristics
• Surface-mountable 14-pin SOIC package design

Applications

• Digital logic circuit design requiring NOR operations
• Computer peripheral interface circuits
• General-purpose digital signal processing systems

Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the SOIC package dimensions and pinout match the target PCB footprint. Ensure the operating temperature range aligns with the intended environmental conditions. Check for any specific handling requirements related to the tape-and-reel packaging format during assembly.

Selection Notes

Select this component when a triple 3-input NOR gate is required in high-speed digital applications. The F/FAST series offers faster switching speeds compared to standard LS or HC families. Consider the 14-pin SOIC package for surface mount assembly constraints. Verify that the 2V to 6V supply voltage range meets the system power requirements.

Part Context

This part is part of Texas Instruments' extensive SN74xx logic family, specifically the F/FAST sub-family designed for speed-critical applications. It serves as a fundamental building block for complex digital logic designs, providing reliable NOR functionality in a compact surface-mount package suitable for modern electronics manufacturing processes.

Replacement Considerations

Compatible substitutes include other SN74F27 variants from Texas Instruments or equivalent parts from manufacturers like ON Semiconductor or NXP, provided they maintain the same logic function, package type, and electrical specifications. Verify pin compatibility and voltage levels before substitution.
