CD74HC20E

Inverter Gates Overview

The CD74HC20E is a dual 4-input positive-NAND gate manufactured by Harris Corporation. It belongs to the HC/UH CMOS logic series and utilizes a 14-pin PDIP package. The device operates within a supply voltage range of 2V to 6V, with a maximum operating temperature of 125°C and a minimum of -55°C. Key electrical parameters include a maximum low-level output current of 5.2mA and a high-speed propagation delay ranging from 10ns to 50ns at a 5V supply.

Inverter Gates Feature Summary

• Dual independent NAND gates with four inputs each
• High-speed CMOS technology for rapid switching
• Wide operating voltage range supporting 2V to 6V systems

Inverter Gates Applications

• Digital logic circuit design requiring NAND functionality
• Signal processing in high-speed data transmission systems
• General-purpose logic control in electronic devices

Inverter Gates Procurement Notes

Verify the manufacturer origin as Harris Corporation, noting that this entity was acquired by Texas Instruments. Confirm the package type is PDIP-14 and check RoHS compliance status, as older Harris production runs may not meet current environmental standards. Ensure the part number suffix 'E' corresponds to the specific tape-and-reel or bulk packaging configuration required for your assembly process.

Inverter Gates Selection Notes

Select the CD74HC20E when a dual 4-input NAND function is required in a CMOS environment. It is suitable for designs needing wide voltage tolerance and moderate speed. Compare against SN74HC20 equivalents if sourcing from Texas Instruments directly. Consider the PDIP package constraints for through-hole mounting requirements versus surface-mount alternatives like SOIC or TSSOP if space is limited.

Inverter Gates Part Context

This component is part of the standard 74HC logic family, widely used in digital electronics for basic logic operations. Harris Corporation produced these before its semiconductor division was acquired by Texas Instruments. The CD74HC20E serves as a fundamental building block for complex logic circuits, offering reliability and compatibility with other HC-series components.

Inverter Gates Replacement Considerations

The SN74HC20E is the direct equivalent from Texas Instruments following the acquisition of Harris's semiconductor assets. Other compatible parts include the MC74HC20A from ON Semiconductor or the HD74HC20P from Renesas. Verify pinout compatibility and electrical specifications before substitution.
