Substitute Part Grouping Explanation
Substitution of the MAX4535CUD is determined by strict equivalence across the following critical parameters:
- Switch Circuit Configuration: DPST - NO topology must be maintained
- Multiplexer/Demultiplexer Circuit: 2:1 configuration required
- Number of Circuits: 2 circuits mandatory
- On-State Resistance (Max): 400Ohm specification
- Channel-to-Channel Matching (ΔRon): 2Ohm tolerance
- Supply Voltage Ranges: Single supply (9V–36V) and dual supply (±4.5V–20V)
- Switching Performance: Ton/Toff specifications (275ns/200ns)
- Package / Case: 14-TSSOP form factor with identical physical dimensions
- Mounting Type: Surface Mount requirement
The MAX4535CUD+ meets all these criteria and is classified as a parametric equivalent. The primary distinction is product status and compliance certification.
