Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN7447ANE4 is determined by the following critical parameters:

• Circuit Configuration: 1 x 4:1 decoder function
• Package Type: 16-DIP (0.300", 7.62mm) form factor
• Voltage Supply Range: 4.75V ~ 5.25V single supply
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Through Hole
• Compliance: ROHS3 Compliant

The SN7447AN meets all these criteria and is classified as the manufacturer-recommended substitute. Both parts share identical electrical specifications, package dimensions, and compliance certifications, enabling direct functional replacement.
