CD74HCT00M

Inverter Gates Overview

The CD74HCT00M is a quad 2-input NAND gate integrated circuit manufactured by Harris Corporation. It belongs to the 74HCT logic series, utilizing CMOS technology with buffered inputs for compatibility with TTL-driven systems. The device operates within a supply voltage range of 4.5V to 5.5V and features a typical propagation delay of 7ns at VCC = 5V with a load capacitance of 15pF. It supports a maximum propagation delay of 20ns at 4.5V with 50pF load. The input high logic level is specified at 2V. The component is housed in a 14-pin SOIC package and functions across an operating temperature range of -55°C to 125°C.

Inverter Gates Feature Summary

• Quad configuration providing four independent 2-input NAND gates within a single package
• CMOS construction with buffered inputs ensuring high noise immunity and TTL compatibility
• Wide operating temperature range suitable for industrial and military environments

Inverter Gates Applications

• Digital logic circuits requiring basic NAND operations
• Signal gating and switching applications
• Data routing and selection networks

Inverter Gates Procurement Notes

Verify the manufacturer designation on the component marking, as Harris Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix 'M' corresponds to the SOIC package variant. Check RoHS compliance status, as older Harris production runs may not meet current environmental regulations. Ensure the source document explicitly identifies the part as Harris Corporation product rather than a generic equivalent.

Inverter Gates Selection Notes

Select this component when a quad NAND gate solution is required with HCT-level input compatibility. The 7ns typical propagation delay makes it suitable for general-purpose digital logic where moderate speed is sufficient. Consider the 14-SOIC package constraints for PCB layout. Verify that the 4.5V to 5.5V supply voltage range aligns with the system power design.

Inverter Gates Part Context

The CD74HCT00M is part of the broader 74HCT family of logic devices produced by Harris Semiconductor. This family was designed to bridge the gap between standard CMOS logic and Transistor-Transistor Logic (TTL) standards. Harris Semiconductor was a major producer of these components before its semiconductor division was acquired by Texas Instruments, which continues to manufacture compatible parts under similar numbering schemes.

Inverter Gates Replacement Considerations

Public confirmed substitute part numbers include CD74HC00M and CD74HCT00 from other manufacturers. Verify pinout compatibility and electrical specifications before substitution.
