Number of circuits (2)
Multiplexer/demultiplexer circuit topology (2:1)
Package type (16-SOIC surface mount)
Supply voltage compatibility (single or dual supply ranges)
Operating temperature range

Substitution Groups:

Group 1: Direct Functional Equivalents (MAX383 Series) The MAX383CSE+, MAX383CSE+T, MAX383ESE+, and MAX383ESE+T from Analog Devices Inc./Maxim Integrated are functionally equivalent SPDT 2-circuit switches in 16-SOIC packaging. These parts maintain the same circuit topology and supply voltage ranges (3V ~ 15V single supply, ±3V ~ 8V dual supply). The on-state resistance is 35Ohm (compared to 30Ohm for PS383ESE), representing a 5Ohm increase. All MAX383 variants are RoHS3 compliant and carry active product status, making them suitable for new designs requiring RoHS compliance.

Group 2: Higher Voltage, Higher Resistance Alternatives (MAX4632 Series) The MAX4632CSE+, MAX4632CSE+T, and MAX4632ESE+ are SPDT 2-circuit switches with different electrical characteristics. These parts operate at higher supply voltages (9V ~ 36V single supply, ±4.5V ~ 18V dual supply) and feature higher on-state resistance of 85Ohm. The MAX4632 series is suitable only for applications where the higher voltage range and increased resistance are acceptable trade-offs.

Engineering Selection Recommendations

For RoHS3 Compliant Designs with Standard Supply Voltages: The MAX383 series (MAX383CSE+, MAX383CSE+T, MAX383ESE+, MAX383ESE+T) represents the primary substitution path for PS383ESE. All variants are RoHS3 compliant with active product status, ensuring long-term availability and regulatory compliance. The MAX383ESE+ and MAX383ESE+T variants support the full operating temperature range of -40°C to 85°C, matching the PS383ESE specification. The MAX383CSE+ and MAX383CSE+T variants operate within 0°C to 70°C, suitable for standard industrial applications. Packaging options include Tube (CSE+, ESE+) and Tape & Reel (CSE+T, ESE+T) formats.

For Higher Voltage Applications: The MAX4632 series (MAX4632CSE+, MAX4632CSE+T, MAX4632ESE+) is applicable only when supply voltage requirements exceed 9V single supply or ±4.5V dual supply. These parts are not suitable as direct replacements for standard 3V to 15V single supply applications due to their higher voltage operating range and increased on-state resistance of 85Ohm.

For Extended Temperature Range Requirements: Applications requiring operation across -40°C to 85°C should specify MAX383ESE+, MAX383ESE+T, or MAX4632ESE+ to maintain full temperature coverage. The MAX383CSE+ and MAX383CSE+T variants are limited to 0°C to 70°C operation.

Packaging Considerations: Tube packaging (CSE+, ESE+) is suitable for lower-volume applications and manual assembly. Tape & Reel packaging (CSE+T, ESE+T) is recommended for high-volume production and automated pick-and-place assembly.

Frequently Asked Questions (FAQ)

Q: Can MAX383 series parts directly replace PS383ESE in existing designs? A: The MAX383 series maintains functional equivalence with PS383ESE in terms of circuit topology, pin configuration, and supply voltage ranges. The primary differences are on-state resistance (35Ohm vs. 30Ohm), channel-to-channel matching (500mOhm vs. 200mOhm), and switch timing (175ns/100ns vs. 130ns/75ns). Applications with tight resistance or timing specifications require circuit re-evaluation.

Q: What is the difference between MAX383CSE+ and MAX383ESE+ variants? A: Both are functionally identical SPDT 2-circuit switches with 35Ohm on-state resistance. The primary difference is operating temperature range: MAX383CSE+ operates 0°C to 70°C, while MAX383ESE+ operates -40°C to 85°C. Select MAX383ESE+ for extended temperature applications.

Q: What is the difference between Tube and Tape & Reel packaging? A: Tube packaging (CSE+, ESE+) contains loose components suitable for manual handling and lower-volume assembly. Tape & Reel packaging (CSE+T, ESE+T) provides components on continuous tape for automated assembly equipment. Both contain identical die and electrical specifications.

Q: Are MAX4632 parts suitable replacements for PS383ESE? A: MAX4632 parts are not direct replacements. They operate at higher supply voltages (9V ~ 36V) and feature significantly higher on-state resistance (85Ohm). Use MAX4632 only when your application requires higher voltage operation and can tolerate increased resistance.

Q: Is RoHS compliance important for PS383ESE substitution? A: The PS383ESE is RoHS non-compliant. All recommended MAX383 and MAX4632 substitutes are ROHS3 compliant. For new designs and applications subject to RoHS regulations, specify compliant alternatives.

Q: What is the impact of increased on-state resistance in MAX383 substitutes? A: The MAX383 series has 35Ohm on-state resistance compared to PS383ESE at 30Ohm. This 5Ohm increase affects signal attenuation and power dissipation in analog switching applications. Verify that your circuit design tolerates this resistance increase, particularly in low-impedance signal paths.
