74F374PC Equivalent & Substitute Parts

Part Overview

The 74F374PC is a D-Type flip-flop logic integrated circuit featuring 1 element with 8-bit capacity and positive edge triggering. Manufactured by onsemi in a 20-DIP through-hole package, this component operates at a clock frequency of 140 MHz with a maximum propagation delay of 8.5ns at 5V with 50pF load. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy compatibility is required.

Engineering Selection Recommendations

The SN74F374N from Texas Instruments is the direct equivalent substitute for the obsolete 74F374PC. Both components share identical functional specifications, electrical characteristics, and physical packaging. The SN74F374N provides the additional advantage of active product status, ensuring continued availability and supply chain reliability. The SN74F374N carries ROHS3 compliance certification, meeting modern environmental and regulatory requirements where the original 74F374PC does not specify such compliance. Both components maintain REACH Unaffected status. The clock frequency specification difference (100 MHz for SN74F374N versus 140 MHz for 74F374PC) does not affect substitution compatibility, as the SN74F374N meets the identical propagation delay specification of 8.5ns at 5V with 50pF load, which is the controlling parameter for timing-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the SN74F374N directly replace the 74F374PC without circuit modifications?

A: Yes. The SN74F374N is a direct functional and pin-compatible equivalent. Both components feature identical 20-DIP through-hole packaging, tri-state non-inverted output configuration, 8-bit D-type flip-flop architecture, and electrical specifications including voltage supply range (4.5V ~ 5.5V), propagation delay (8.5ns @ 5V, 50pF), and output current ratings (3mA high, 24mA low).

Q: Why does the SN74F374N have a lower clock frequency specification than the 74F374PC?

A: The clock frequency specification difference (100 MHz versus 140 MHz) reflects manufacturer rating practices and does not indicate functional incompatibility. The critical timing parameter for substitution is the maximum propagation delay, which is identical at 8.5ns for both components at 5V with 50pF load. This propagation delay specification governs actual circuit performance in timing-critical applications.

Q: What is the significance of the SN74F374N being listed as Active product status?

A: Active product status indicates that the SN74F374N is currently manufactured and available through normal distribution channels. This contrasts with the 74F374PC, which is obsolete and no longer manufactured. Active status ensures long-term supply chain availability and support.

Q: Does the ROHS3 compliance of the SN74F374N affect electrical compatibility?

A: No. ROHS3 compliance is an environmental and regulatory certification that does not alter the electrical or functional characteristics of the component. It indicates that the SN74F374N meets Restriction of Hazardous Substances requirements, making it suitable for applications with environmental compliance mandates.

Q: Are there any packaging or mounting differences between the 74F374PC and SN74F374N?

A: No. Both components use identical 20-DIP (0.300", 7.62mm) through-hole packaging and mounting configuration. They are mechanically and electrically interchangeable at the board level.
