Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX908CSD is determined by strict equivalence across the following critical parameters:

• Number of comparator elements: 4
• Output type: TTL
• Supply voltage range: 4.5V ~ 11V
• Input offset voltage: 2mV @ 5V maximum
• Input bias current: 0.3µA @ 5V maximum
• Quiescent current: 1mA maximum
• CMRR / PSRR: 86.02dB minimum
• Propagation delay: 50ns maximum
• Package: 14-SOIC surface mount
• Operating temperature range: 0°C ~ 70°C

The MAX908CSD+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and packaging format.
