Substitute Part Grouping Explanation

Substitution for the SN74ALS86DRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, output current 400µA/8mA, input logic levels 0.8V/2V, propagation delay 17ns @ 5V/50pF
• Package: 14-SOIC surface mount form factor
• Operating Temperature Range: 0°C ~ 70°C
• Compliance: ROHS3 Compliant, MSL Level 1

The SN74ALS86DR qualifies as a direct substitute based on identical electrical and functional parameters. The primary distinction is packaging format and product availability status.
