Substitute Part Grouping Explanation

Substitution for the 74HCT30N,652 is determined by the following critical parameters:

• Logic Function: NAND Gate with 1 channel and 8 inputs
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, quiescent current 2 µA maximum, output current 4mA, propagation delay 28ns @ 4.5V with 50pF load
• Input Logic Levels: Low 0.8V, High 2V
• Package Compatibility: 14-DIP through-hole mounting with 0.300" (7.62mm) pitch
• Base Product Series: 74HCT30

The CD74HCT30E from Harris Corporation meets all electrical and mechanical substitution criteria. Both parts share identical logic function, pin configuration, and core electrical parameters, enabling direct functional replacement in 14-DIP through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The CD74HCT30E is a direct functional equivalent to the 74HCT30N,652. Both components are obsolete products, and selection between them should be based on availability and application requirements.

The CD74HCT30E offers an extended lower operating temperature limit of -55°C compared to the 74HCT30N,652 at -40°C, providing broader temperature range coverage for applications requiring enhanced cold-temperature performance.

Compliance considerations: The 74HCT30N,652 is RoHS3 compliant, while the CD74HCT30E is RoHS non-compliant. Applications subject to RoHS requirements must use the 74HCT30N,652 or identify alternative compliant sources.

Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT30E directly replace the 74HCT30N,652 in existing designs?
