Substitute Part Grouping Explanation
Substitution eligibility for the MAX4589CAP is determined by strict equivalence across the following critical parameters:
- Multiplexer/Demultiplexer circuit configuration (2:1)
- Switch circuit topology (DPST)
- Number of channels (2)
- On-state resistance maximum rating (60Ω)
- Supply voltage ranges (Single: 2.7V ~ 12V; Dual: ±2.7V ~ 6V)
- Bandwidth specification (-3dB: 200MHz)
- Package type and pinout (20-SSOP)
- Feature set (Break-Before-Make, SPI, T-Switch Configuration)
The MAX4589CAP+ qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction between these parts is product status and packaging format, not functional capability.
