MAX396EWI Equivalent & Substitute Parts

Part Overview

The MAX396EWI is a 16:1 analog multiplexer IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-SOIC surface mount package. This component functions as a single-circuit switch with 100Ohm on-state resistance, designed for signal routing and channel selection applications. The MAX396EWI is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. Substitute parts must maintain compatibility across electrical performance parameters, package form factor, and operating conditions.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX396EWI is determined by the following critical parameters:

Primary Compatibility Criteria:

Multiplexer configuration: 16:1
Number of circuits: 1
Package form factor: 28-SOIC surface mount
Operating temperature range: -40°C ~ 85°C minimum

Secondary Performance Criteria:

On-state resistance: 100Ohm nominal
Supply voltage compatibility with application requirements

Engineering Selection Recommendations

MAX396EWI+ (Direct Successor) The MAX396EWI+ is the active production equivalent from Analog Devices Inc./Maxim Integrated. It maintains identical electrical specifications to the MAX396EWI while offering ROHS3 compliance and active product status. This part is the preferred direct replacement for applications requiring no design modification. Packaging is available in Tube format.

DG406DYZ and DG406DYZ-T (Renesas Electronics) Both DG406DYZ variants from Renesas Electronics Corporation provide 16:1 multiplexer functionality in 28-SOIC packages with active product status and ROHS3 compliance. These parts feature expanded supply voltage ranges (5V ~ 34V single supply, ±5V ~ 20V dual supply) compared to the MAX396EWI. Channel-to-channel matching tolerance is wider (5Ohm vs. 1.8Ohm), and charge injection is higher (40pC vs. 2pC). DG406DYZ-T offers higher inventory availability in Cut Tape and Digi-Reel packaging. Selection between DG406DYZ and DG406DYZ-T depends on packaging and quantity requirements.

DG506BEW-T1-GE3 (Vishay Siliconix) The DG506BEW-T1-GE3 from Vishay Siliconix is a 16:1 multiplexer with 300Ohm on-state resistance, representing a higher-resistance alternative. This part offers the widest operating temperature range (-40°C ~ 125°C), lowest charge injection (1pC), and lowest leakage current (1nA). It is suitable for applications where higher on-state resistance is acceptable and superior temperature performance or lower charge injection is required. ROHS3 compliance and MSL 1 rating are provided.

Frequently Asked Questions (FAQ)

Q: Can MAX396EWI+ be used as a direct replacement for MAX396EWI? A: Yes. MAX396EWI+ maintains identical electrical specifications and 28-SOIC package form factor. The primary difference is active product status and ROHS3 compliance. No circuit redesign is required.

Q: What are the key differences between Renesas DG406DYZ variants and the MAX396EWI? A: DG406DYZ parts support higher supply voltages (5V ~ 34V single supply vs. 2.7V ~ 16V) and dual supply ranges (±5V ~ 20V vs. ±2.7V ~ 8V). Channel-to-channel matching tolerance is wider (5Ohm vs. 1.8Ohm), and charge injection is higher (40pC vs. 2pC). On-state resistance remains 100Ohm. Selection depends on application supply voltage requirements and tolerance specifications.

Q: When should DG506BEW-T1-GE3 be considered? A: DG506BEW-T1-GE3 is appropriate when on-state resistance of 300Ohm is acceptable and superior performance in charge injection (1pC), leakage current (1nA), or extended temperature range (-40°C ~ 125°C) is required. This part is not suitable for applications requiring 100Ohm on-state resistance.

Q: Are all substitute parts available in 28-SOIC package? A: Yes. All identified substitutes are housed in 28-SOIC surface mount packages with identical physical dimensions (0.295", 7.50mm Width), ensuring PCB footprint compatibility.
