Substitute Part Grouping Explanation

Substitute parts for the 74F158APC are identified based on strict parametric equivalence. The following criteria determine substitutability:

• Circuit configuration: 4 x 2:1 multiplexer topology
• Package type: 16-DIP (0.300", 7.62mm) through-hole mounting
• Voltage supply range: 4.5V ~ 5.5V single supply
• Output current specifications: 1mA high, 20mA low
• Operating temperature range: 0°C ~ 70°C
• Logic series compatibility: 74F family

The SN74F157AN meets all these parametric requirements and serves as a direct functional equivalent.
