Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC30PW,112 is determined by the following criteria:

Electrical Compatibility Requirements:

• Logic type must be NAND gate with 1 channel and 8 inputs
• Supply voltage range must encompass or match 2V ~ 6V
• Input and output logic levels must be compatible
• Quiescent current and output drive capabilities must meet or exceed specifications

Mechanical Compatibility Requirements:

• Package type must be 14-TSSOP surface mount
• Physical dimensions must match 0.173" × 4.40mm width specification
• Mounting footprint must be identical for PCB compatibility

Compliance Requirements:

• RoHS3 compliance required
• MSL rating of 1 or better acceptable

All substitute parts listed maintain identical functional specifications and package geometry, enabling direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CD74HC30PWR (Texas Instruments)

The CD74HC30PWR is the preferred substitute for new designs and production. This part maintains active product status, ensuring long-term availability and supply chain stability. It meets all electrical and mechanical compatibility requirements with identical propagation delay performance (22ns @ 6V, 50pF). The extended operating temperature range (-55°C ~ 125°C) provides additional margin beyond the original specification. Tape & Reel packaging supports high-volume manufacturing processes.

Secondary Recommendation: MC74HC30ADTR2G (onsemi)

The MC74HC30ADTR2G serves as an alternative active substitute from onsemi. All electrical parameters align with the original part, with the exception of propagation delay (30ns @ 6V, 50pF), which remains within acceptable logic gate performance tolerances. This part is suitable for applications where timing margins accommodate the 8ns delay increase. Active product status ensures continued availability.

Discontinued Alternatives: CD74HC30PW and CD74HC30PWT (Texas Instruments)

Both CD74HC30PW and CD74HC30PWT are functionally equivalent but carry discontinued status at DiGi Electronics. These parts may be sourced from inventory channels but do not provide long-term supply assurance. Selection should occur only when CD74HC30PWR availability is constrained.

All substitute parts comply with RoHS3 requirements and maintain MSL rating 1, meeting environmental and moisture sensitivity specifications.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC30PWR directly replace the 74HC30PW,112 on existing PCBs?

A: Yes. The CD74HC30PWR maintains identical 14-TSSOP package geometry and pin configuration. No PCB modifications are required for direct substitution.

Q: What is the significance of the propagation delay difference in MC74HC30ADTR2G?

A: The MC74HC30ADTR2G specifies 30ns maximum propagation delay compared to 22ns for the original part. This 8ns difference is typical among 74HC30 variants and remains within standard logic gate performance parameters. Applications with timing-critical requirements should evaluate this specification against circuit timing margins.

Q: Why is the operating temperature range different between the original part and substitutes?

A: The 74HC30PW,112 specifies -40°C ~ 125°C, while substitute parts extend to -55°C ~ 125°C. The extended lower temperature limit in substitutes provides additional design margin and does not affect compatibility. Designs operating within the original -40°C minimum remain fully compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, meeting environmental and hazardous substance restrictions.

Q: What packaging formats are available for the substitute parts?

A: CD74HC30PW is supplied in Tube format. CD74HC30PWR and MC74HC30ADTR2G are supplied in Tape & Reel format, which is standard for high-volume surface mount assembly. Tube packaging is suitable for lower-volume or manual assembly processes.

Q: Is the 74HC30PW,112 still available for purchase?

A: The 74HC30PW,112 is classified as obsolete. While inventory may exist in distribution channels, new designs should transition to active substitute parts such as CD74HC30PWR or MC74HC30ADTR2G to ensure long-term supply continuity.
