74F112PC Equivalent & Substitute Parts

Part Overview

The 74F112PC is a dual JK-type flip-flop logic integrated circuit manufactured by onsemi, housed in a 16-DIP (0.300", 7.62mm) through-hole package. This device provides two independent 1-bit JK flip-flops with complementary outputs, preset and reset functionality, and negative edge triggering. The 74F112PC is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance, repair, and legacy design support.

Substitute Part Grouping Explanation

Substitution of the 74F112PC is determined by strict equivalence across the following critical parameters:

Functional Equivalence: The substitute part must be a dual JK-type flip-flop with 1-bit per element, complementary outputs, and negative edge triggering.

Electrical Compatibility: The substitute must operate within the same voltage supply range (4.5V ~ 5.5V), maintain identical propagation delay specifications (6.5 ns @ 5V, 50pF), and support the same output current ratings (1 mA high, 20 mA low).

Package Compatibility: The substitute must use the 16-DIP (0.300", 7.62mm) through-hole package to ensure direct socket compatibility without PCB redesign.

Series Alignment: The substitute must belong to the 74F logic series, ensuring consistent TTL-compatible timing and electrical characteristics.

The SN74F112N from Texas Instruments meets all substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The SN74F112N is the direct functional equivalent of the 74F112PC and is suitable for replacement in all applications where the 74F112PC was originally specified. The SN74F112N maintains identical electrical performance across all critical parameters: propagation delay, output current ratings, supply voltage range, and operating temperature specifications.

The SN74F112N holds active product status with current manufacturing support from Texas Instruments, ensuring long-term availability and supply chain reliability. The device is ROHS3 compliant, meeting modern environmental and regulatory requirements. Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming regulatory equivalence.

The higher clock frequency specification of the SN74F112N (130 MHz versus 105 MHz) represents an enhancement that does not compromise backward compatibility. The 16-DIP through-hole package is identical between both parts, enabling direct socket substitution without PCB modification.

Frequently Asked Questions (FAQ)

Q: Can the SN74F112N be used as a direct replacement for the 74F112PC without circuit modification?

A: Yes. The SN74F112N is functionally and electrically equivalent to the 74F112PC across all critical parameters. The identical 16-DIP package enables direct socket substitution. No circuit redesign is required.

Q: What is the primary difference between the 74F112PC and SN74F112N?
