Substitute Part Grouping Explanation

Substitution for the SN74AS298ADRG4 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 4 x 2:1 multiplexer topology
• Package type: 16-SOIC surface mount
• Voltage supply range: 4.5V ~ 5.5V
• Output current specifications: 2mA high, 20mA low
• Operating temperature range: 0°C ~ 70°C
• Compliance certifications: ROHS3, REACH Unaffected

The SN74AS298AD qualifies as a direct substitute based on identical electrical specifications and package requirements. The primary distinction is product status: the substitute part is active in production, whereas the original part is obsolete.
