Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74ACT112M is determined by strict equivalence across the following critical parameters:

• Logic Function: Dual JK-type flip-flop with 1-bit per element
• Electrical Performance: Clock frequency of 100 MHz, propagation delay of 10.3 ns @ 5V/50pF, output drive capability of 24 mA
• Trigger Mechanism: Negative edge triggering with complementary outputs
• Power Supply: 4.5V to 5.5V operating range
• Package Compatibility: 16-SOIC surface mount package with identical pinout
• Compliance: ROHS3 compliance and MSL Level 1 rating

Substitute parts must maintain identical electrical characteristics, functional behavior, and physical package specifications to ensure direct replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The CD74ACT112M96 is the direct functional equivalent of the CD74ACT112M. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are housed in the same 16-SOIC package. The primary distinction is product status and packaging format: the CD74ACT112M is Last Time Buy (end-of-life), while the CD74ACT112M96 maintains Active status with ongoing manufacturing support.

For new designs or production continuity, the CD74ACT112M96 is the appropriate selection. Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing processes and environmental standards. The packaging difference (Tube versus Tape & Reel) reflects supply chain availability and does not affect electrical or functional performance.

Frequently Asked Questions (FAQ)

Q: Can CD74ACT112M96 be used as a direct replacement for CD74ACT112M?

A: Yes. The CD74ACT112M96 is electrically and functionally identical to the CD74ACT112M. Both devices provide dual JK-type flip-flops with identical electrical performance, operating ranges, and 16-SOIC package specifications. Direct substitution is possible without circuit modification.

Q: What is the difference between the Tube and Tape & Reel packaging formats?

A: Tube packaging (CD74ACT112M) is used for lower-volume orders and manual handling, while Tape & Reel packaging (CD74ACT112M96) is optimized for automated assembly processes. The electrical and functional characteristics are identical; the difference is in supply chain logistics and handling method.

Q: Why is CD74ACT112M marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this specific part number. The CD74ACT112M96 represents the active production equivalent, ensuring continued availability and supply chain reliability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both CD74ACT112M and CD74ACT112M96 maintain identical ROHS3 compliance and MSL Level 1 ratings. They are suitable for the same applications and manufacturing environments.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: dual JK-type flip-flop configuration, 100 MHz clock frequency, 10.3 ns propagation delay, negative edge triggering, 24 mA output drive, 4.5V to 5.5V supply voltage, and 16-SOIC package format. Any deviation in these parameters requires circuit re-evaluation.
