Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LS86ADRE4 is determined by strict equivalence across the following critical parameters:

• Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
• Voltage Supply Range: 4.75V ~ 5.25V
• Output Current Specifications: 400µA (high), 8mA (low)
• Input Logic Levels: 0.8V (low), 2V (high)
• Propagation Delay: 30ns @ 5V, 15pF
• Operating Temperature Range: 0°C ~ 70°C
• Package Configuration: 14-SOIC surface mount
• Compliance: ROHS3 Compliant, MSL Level 1

The SN74LS86ADR meets all these parameters and qualifies as a parametric equivalent substitute.
