Substitute Part Grouping Explanation

Substitution eligibility for the 74F374MSA is determined by strict alignment of the following critical parameters:

• Base product number: 74F374
• Type: D-Type flip-flop
• Number of elements: 1
• Number of bits per element: 8
• Output type: Tri-State, Non-Inverted
• Trigger type: Positive Edge
• Package / Case: 20-SSOP (0.209", 5.30mm Width)
• Mounting type: Surface Mount
• Voltage supply range: 4.5V ~ 5.5V
• Operating temperature: 0°C ~ 70°C

The SN74F374DBR from Texas Instruments meets all substitution criteria. While the clock frequency specification differs (100 MHz vs. 140 MHz), the maximum propagation delay remains identical at 8.5ns @ 5V, 50pF, ensuring functional compatibility in circuit applications.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the SN74F374DBR replace the 74F374MSA in existing designs?

A: Yes. Both parts share identical functional specifications including propagation delay (8.5ns @ 5V, 50pF), output drive characteristics (3mA/24mA), supply voltage range (4.5V ~ 5.5V), and package geometry (20-SSOP). Pin-to-pin compatibility is maintained.

Q: What is the difference in clock frequency between these parts?

A: The 74F374MSA specifies 140 MHz while the SN74F374DBR specifies 100 MHz. However, both parts deliver identical maximum propagation delay of 8.5ns at rated conditions, which is the controlling parameter for timing performance in digital circuits.

Q: Are there packaging differences between these parts?

A: No. Both parts use the 20-SSOP (0.209", 5.30mm Width) surface mount package with identical pin assignments and mechanical dimensions.

Q: What compliance certifications apply to the substitute part?

A: The SN74F374DBR is RoHS3 compliant and carries REACH Unaffected status. Both parts are classified under ECCN EAR99.

Q: Why is the 74F374MSA listed as obsolete?

A: The 74F374MSA is an obsolete product from onsemi. The SN74F374DBR from Texas Instruments is an active equivalent that provides continued availability and supply security.
