74HC112PW,112 Equivalent & Substitute Parts

Part Overview

The 74HC112PW,112 is a dual JK-type flip-flop logic integrated circuit manufactured by Nexperia USA Inc. in a 16-TSSOP surface mount package. This component functions as a Set(Preset) and Reset element with complementary outputs, operating across a 2V to 6V supply voltage range. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives from active manufacturers for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC112PW,112 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Base product number: 74HC112
• Functional type: JK-type dual flip-flop with 2 elements, 1 bit per element
• Output configuration: Complementary outputs
• Trigger mechanism: Negative edge triggered
• Package format: 16-TSSOP surface mount
• Supply voltage range: 2V ~ 6V minimum compatibility
• Operating temperature range: Must support -40°C to 125°C minimum

Acceptable Variation Parameters:

• Clock frequency (provided specifications vary; lower frequencies remain compatible)
• Propagation delay (provided specifications vary; longer delays remain compatible)
• Input capacitance (provided specifications vary; higher values remain compatible)
• Packaging format (Tube, Tape & Reel acceptable as mechanical alternatives)
• Manufacturer identity (multiple qualified sources available)

Substitute parts must maintain identical functional behavior, pinout compatibility, and electrical operating characteristics within the specified voltage and temperature ranges.

Engineering Selection Recommendations

Texas Instruments CD74HC112 Series (Upgrade Path)

The CD74HC112PW, CD74HC112PWR, and CD74HC112PWT from Texas Instruments represent the primary upgrade path from the obsolete Nexperia 74HC112PW,112. All three variants maintain identical electrical specifications and 16-TSSOP package compatibility. CD74HC112PWR is the recommended selection for new production due to active product status and Tape & Reel packaging availability. CD74HC112PW and CD74HC112PWT are discontinued at DiGi Electronics but remain functionally equivalent. The extended operating temperature range (-55°C to 125°C) of Texas Instruments variants provides enhanced thermal margin compared to the original Nexperia specification.

onsemi MC74HC112 Series (Alternative Source)

The MC74HC112ADTG and MC74HC112ADTR2G from onsemi provide functionally equivalent alternatives with active product status. Both variants feature improved propagation delay performance (21ns versus 30ns at 6V, 50pF load), enabling operation in timing-critical applications. The extended operating temperature range (-55°C to 125°C) matches Texas Instruments specifications. MC74HC112ADTR2G in Tape & Reel format is preferred for high-volume production; MC74HC112ADTG in Tube format suits lower-volume requirements.

Compliance and Certification

All substitute parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (unlimited shelf life), and REACH unaffected status, matching the original part's regulatory profile. ECCN and HTSUS classifications remain consistent across all variants.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 74HC112PW,112 with any of the listed substitutes?

A: Yes. All listed substitutes maintain identical pinout, package format (16-TSSOP), and functional behavior as dual JK-type flip-flops with negative edge triggering and complementary outputs. Direct PCB substitution is supported without circuit modification.

Q: What is the difference between CD74HC112PW, CD74HC112PWR, and CD74HC112PWT?

A: These three Texas Instruments variants are electrically identical. The differences are packaging format only: PW uses Tube packaging, PWR uses Tape & Reel format, and PWT uses Tape & Reel format. Select based on procurement and assembly requirements. CD74HC112PWR is recommended for new designs due to active product status.

Q: Why do onsemi MC74HC112 parts show faster propagation delay (21ns vs 30ns)?

A: The MC74HC112ADTG and MC74HC112ADTR2G achieve 21ns propagation delay at 6V with 50pF load, compared to 30ns for the original and Texas Instruments variants. This represents improved performance and remains fully compatible. Faster propagation delay does not create compatibility issues in applications designed for the original 30ns specification.

Q: Are there temperature range considerations when substituting?

A: The original 74HC112PW,112 operates from -40°C to 125°C. All substitute parts extend the lower temperature limit to -55°C, providing enhanced cold-temperature performance. This extended range is backward compatible with the original specification and introduces no compatibility concerns.

Q: Which substitute should I select for new production?

A: CD74HC112PWR (Texas Instruments, Tape & Reel, Active status) is the primary recommendation for new production designs. MC74HC112ADTR2G (onsemi, Tape & Reel, Active status) serves as a qualified alternative source. Both parts offer active product status, high inventory availability, and full functional equivalence.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance, Moisture Sensitivity Level 1, and REACH unaffected status, matching the original part's regulatory requirements.
