Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC112MT is determined by the following critical parameters:

• Functional equivalence: JK-type flip-flop with 2 elements, 1 bit per element, complementary outputs, negative edge trigger
• Electrical compatibility: Supply voltage range 2V to 6V, output current capability 5.2 mA minimum
• Timing specifications: Maximum propagation delay at 6V, 50pF load
• Package compatibility: 16-SOIC surface mount form factor
• Regulatory compliance: ROHS3 compliance, REACH unaffected status, MSL 1 rating

Substitute parts are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and manufacturer-recommended alternatives (functionally equivalent with minor specification variations).

Parameter Comparison

Engineering Selection Recommendations

CD74HC112M96 (Texas Instruments) is the primary substitute for CD74HC112MT. Both parts are manufactured by Texas Instruments with identical electrical specifications, clock frequency, propagation delay, and operating temperature range. CD74HC112M96 maintains Active product status, ensuring continued availability and manufacturing support. This part is recommended for direct replacement in new designs and inventory replenishment.

74HC112D,653 (Nexperia USA Inc.) is functionally equivalent with higher clock frequency (71 MHz) and lower input capacitance (4.6 pF). This part operates within the specified supply voltage and output current parameters. The operating temperature range is -40°C to 125°C, which is narrower than the original part. This part is suitable for applications not requiring the full -55°C lower temperature limit. Nexperia maintains Active product status with higher inventory availability.

MC74HC112ADR2G (onsemi) is functionally equivalent with Active product status and Tape & Reel packaging. This part features lower propagation delay (21 ns) and lower clock frequency (35 MHz) compared to the original specification. The part maintains full -55°C to 125°C operating temperature range and identical output current capability. This part is suitable for applications where lower propagation delay is beneficial.

MC74HC112ADG (onsemi) is functionally equivalent but carries Obsolete product status. This part should not be selected for new designs or long-term inventory planning due to end-of-life designation.

Frequently Asked Questions (FAQ)

Q: Can CD74HC112M96 be used as a direct replacement for CD74HC112MT?

A: Yes. CD74HC112M96 is a parametric equivalent manufactured by Texas Instruments with identical electrical specifications, clock frequency (60 MHz), propagation delay (30 ns @ 6V, 50pF), and operating temperature range (-55°C to 125°C). Both parts use 16-SOIC surface mount packaging. The primary difference is product status: CD74HC112M96 is Active while CD74HC112MT is Last Time Buy.

Q: What are the key differences between the Nexperia 74HC112D,653 and the original CD74HC112MT?

A: The Nexperia part offers higher clock frequency (71 MHz versus 60 MHz) and lower input capacitance (4.6 pF versus 10 pF). The operating temperature range is narrower: -40°C to 125°C versus -55°C to 125°C. All other electrical parameters including propagation delay, supply voltage range, and output current are identical. Both use 16-SOIC packaging.

Q: Are there packaging format differences between substitute parts?

A: Yes. CD74HC112MT and CD74HC112M96 are supplied in Tape & Reel (TR) format. The Nexperia 74HC112D,653 is supplied in Cut Tape (CT) & Digi-Reel format. The onsemi MC74HC112ADG is supplied in Tube format, while MC74HC112ADR2G is supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly line requirements and order quantities.

Q: Why does MC74HC112ADG show Obsolete status?

A: MC74HC112ADG is designated as Obsolete by onsemi, indicating end-of-life production. This part should not be selected for new designs or applications requiring long-term component availability. Active alternatives such as MC74HC112ADR2G should be used instead.

Q: Are all substitute parts ROHS3 compliant and REACH unaffected?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, matching the regulatory compliance profile of the original CD74HC112MT. All parts carry Moisture Sensitivity Level 1 (Unlimited) rating.

Q: What is the significance of propagation delay differences between parts?

A: Propagation delay determines the time required for output changes following clock edge transitions. CD74HC112MT and CD74HC112M96 specify 30 ns maximum delay at 6V with 50pF load. The onsemi parts (MC74HC112ADG and MC74HC112ADR2G) specify 21 ns, offering faster response. The Nexperia part matches the 30 ns specification. Selection depends on timing-critical circuit requirements.

Q: Can the onsemi MC74HC112ADR2G replace CD74HC112MT in temperature-sensitive applications?

A: MC74HC112ADR2G operates across -55°C to 125°C, matching the original part's full temperature range. This part is suitable for temperature-sensitive applications. However, the lower propagation delay (21 ns) may require circuit timing verification to ensure compatibility with existing designs.
