Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74F151BNG4 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 1 x 8:1 multiplexer topology
• Output current specifications: 1mA high, 24mA low
• Supply voltage range: 4.5V ~ 5.5V single supply
• Operating temperature range: 0°C ~ 70°C
• Package type: 16-DIP (0.300", 7.62mm)
• Electrical characteristics: Identical functional performance

The SN74F151BN qualifies as a direct substitute based on complete alignment with these parameters. The primary difference is product status and packaging format, not electrical or mechanical specifications.
