CD74HC30M NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD74HC30M is a NAND Gate IC featuring 1 channel with 8 inputs in a 14-SOIC surface mount package, manufactured by Texas Instruments. This logic component is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement. The 74HC30 series provides standard CMOS logic functionality suitable for digital circuit applications requiring 8-input NAND gate operations across industrial and commercial temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD74HC30M are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Number of Circuits: 1
• Number of Inputs: 8
• Voltage Supply Range: 2V ~ 6V
• Input/Output Logic Levels: Identical thresholds
• Package Type: 14-SOIC or 14-SO (mechanically compatible)

Acceptable Variations:

• Propagation Delay: Up to 30ns @ 6V, 50pF (slight performance variance acceptable)
• Operating Temperature: -40°C ~ 125°C or -55°C ~ 125°C (both acceptable)
• Packaging Format: Tube, Cut Tape, or Tape & Reel (functional equivalence)
• Manufacturer: Texas Instruments, Nexperia USA Inc., or onsemi (all 74HC30 series)

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level 1
• REACH Unaffected status

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs):

CD74HC30M96 is the direct equivalent from Texas Instruments with identical electrical specifications and active product status. This part maintains the same propagation delay (22ns) and temperature range (-55°C ~ 125°C), differing only in packaging format (Cut Tape & Digi-Reel vs. Tube). Selection is appropriate when Texas Instruments sourcing is preferred and tape & reel packaging is acceptable.

74HC30D,653 from Nexperia USA Inc. provides full electrical equivalence with active status and superior inventory availability. The operating temperature range narrows to -40°C ~ 125°C, which is acceptable for most commercial and industrial applications. This part is suitable for applications not requiring the extended -55°C lower temperature limit.

74HC30D-Q100J from Nexperia USA Inc. is qualified to AEC-Q100 automotive standards, making it the appropriate selection for automotive-grade applications. Electrical specifications remain identical to the main part, with the same temperature range limitation (-40°C ~ 125°C).

Secondary Substitutes (Acceptable with Performance Consideration):

MC74HC30ADR2G from onsemi is an active product with full compatibility across all electrical parameters. The propagation delay extends to 30ns (versus 22ns for primary substitutes), which remains within acceptable limits for most digital logic applications. This part is suitable when onsemi sourcing is required or when the slightly relaxed timing specification is acceptable.

MC74HC30ADG from onsemi carries obsolete product status and should be avoided for new designs despite current inventory availability. Use only when existing stock must be consumed in legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can I substitute CD74HC30M with CD74HC30M96?

A: Yes. CD74HC30M96 is a direct functional equivalent with identical electrical specifications. The only difference is packaging format (Cut Tape & Digi-Reel vs. Tube). Both are Texas Instruments products with the same 22ns propagation delay and -55°C ~ 125°C operating range.

Q: What is the difference between 14-SOIC and 14-SO packages?

A: Both designations refer to 14-pin small outline integrated circuits with identical 0.154" (3.90mm) width and pin configurations. These packages are mechanically and electrically interchangeable for PCB assembly purposes.

Q: Why does MC74HC30ADR2G have a 30ns propagation delay instead of 22ns?

A: The 30ns specification represents the maximum propagation delay for onsemi's manufacturing process. This 8ns difference remains within acceptable tolerance for standard CMOS logic applications and does not affect functional compatibility. Applications with strict timing requirements should verify this specification against circuit design margins.

Q: Is 74HC30D-Q100J suitable for automotive applications?

A: Yes. The 74HC30D-Q100J carries AEC-Q100 automotive qualification, making it the appropriate selection for automotive-grade designs. All electrical parameters remain equivalent to the base CD74HC30M.

Q: Can I use parts with -40°C ~ 125°C temperature range in place of -55°C ~ 125°C?

A: This depends on application requirements. If your circuit operates only within the -40°C ~ 125°C range, Nexperia parts (74HC30D,653 and 74HC30D-Q100J) are fully acceptable. If extended low-temperature operation below -40°C is required, select Texas Instruments (CD74HC30M96) or onsemi (MC74HC30ADR2G) parts with -55°C ~ 125°C ratings.

Q: Should I avoid obsolete parts like MC74HC30ADG?

A: Yes, for new designs. Obsolete parts should be reserved for legacy system maintenance only. Active products (CD74HC30M96, 74HC30D,653, 74HC30D-Q100J, MC74HC30ADR2G) provide superior long-term availability and supply chain stability.

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original CD74HC30M specifications.
