CD74HCT03M

Inverter Gates Overview

The CD74HCT03M is a high-speed CMOS logic device manufactured by Harris Corporation, featuring four independent 2-input NAND gates with open-drain outputs. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package. The component supports surface-mount technology and is designed for applications requiring robust digital switching capabilities within standard HCT logic families.

Inverter Gates Feature Summary

• Integrates four independent 2-input NAND logic functions
• Features open-drain output configuration for flexible interfacing
• Constructed using high-speed CMOS technology for efficient performance

Inverter Gates Applications

• Digital signal processing circuits
• General-purpose logic control systems
• Interface buffering between different logic families

Inverter Gates Procurement Notes

Verify the manufacturer designation carefully, as this component was originally produced by Harris Corporation, which has undergone corporate restructuring and acquisition. Ensure the specific suffix matches the required package type and that the source documentation confirms the open-drain characteristic. Cross-reference part numbers with current distributors to confirm availability and authenticity given the historical nature of the original manufacturer.

Inverter Gates Selection Notes

Select this component when a quad NAND gate with open-drain capability is required within a 5V logic system. The HCT series ensures compatibility with TTL-level inputs while maintaining CMOS power advantages. Consider the SOIC package constraints for PCB layout and verify that the open-drain nature aligns with the pull-up requirements of the target circuit design.

Inverter Gates Part Context

This device belongs to the 74HCT logic family, which bridges the gap between older TTL standards and modern CMOS technologies. Originally developed by Harris Semiconductor, these components were widely used in industrial and consumer electronics before the division's integration into other semiconductor entities. The CD74 prefix indicates commercial temperature range variants within the broader 74xx series architecture.

Inverter Gates Replacement Considerations

Compatible substitutes include the Texas Instruments CD74HCT03M96, which shares identical logical functionality and pinout specifications. Verify that any replacement maintains the open-drain output structure and compatible supply voltage ranges to ensure seamless integration without circuit modification.
