MAX392ESE Equivalent & Substitute Parts

Part Overview

The MAX392ESE is a 4-circuit SPST-NO (Single Pole Single Throw - Normally Open) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 35Ohm on-state resistance in a 16-SOIC surface mount package. The MAX392ESE is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain functional compatibility while meeting current RoHS and REACH compliance requirements.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): MAX392ESE+ is the primary recommended substitute. It maintains identical electrical specifications to the MAX392ESE while offering Active product status and RoHS3 compliance. This part is suitable for designs requiring no circuit modifications and is available in Tube packaging.

For Applications Tolerant of Higher On-State Resistance: ADG442BRZ and ADG442BRZ-REEL are suitable when circuit design permits 70Ohm on-state resistance (double that of MAX392ESE). These parts offer improved crosstalk performance (-100dB vs -85dB) and faster off-time (60ns vs 75ns). ADG442BRZ-REEL provides higher inventory availability (17,935 pcs) in Cut Tape & Digi-Reel packaging.

For Extended Temperature Range Applications: ADG1312YRZ-REEL7 extends operating temperature to 105°C and provides 600MHz bandwidth, suitable for high-frequency switching applications. However, 200Ohm on-state resistance requires circuit re-evaluation. DG455EY-T1-E3 offers the widest temperature range (-40°C to 125°C) and lowest on-state resistance (5.3Ohm) for demanding applications.

For Low-Voltage Supply Applications: ALD4202MSCL supports lower supply voltages (3V ~ 12V single, ±1.5V ~ 6V dual) but operates only to 70°C and has 135Ohm on-state resistance. This part is suitable for battery-powered or low-voltage systems with restricted temperature environments.

Not Recommended as Direct Substitute: ADG411BRZ uses SPST-NC (Normally Closed) switch configuration, which is functionally different from the SPST-NO MAX392ESE. This part is suitable only for applications requiring normally-closed switch behavior.

All recommended substitutes are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX392ESE+ be used as a direct drop-in replacement for MAX392ESE? A: Yes. MAX392ESE+ is electrically identical to MAX392ESE with matching on-state resistance (35Ohm), supply voltage ranges, switching times, and leakage specifications. The primary differences are Active product status and RoHS3 compliance. Both use 16-SOIC packaging with identical pinouts.

Q: What is the difference between SPST-NO and SPST-NC switch types? A: SPST-NO (Normally Open) switches are open in the off-state and close when activated. SPST-NC (Normally Closed) switches are closed in the off-state and open when activated. ADG411BRZ is SPST-NC and cannot replace SPST-NO MAX392ESE without circuit redesign.

Q: Can I use ADG442BRZ (70Ohm) instead of MAX392ESE (35Ohm)? A: Substitution depends on circuit design. The doubled on-state resistance (70Ohm vs 35Ohm) increases voltage drop across the switch and may affect signal integrity in low-impedance applications. Verify that your circuit tolerates this resistance increase and the resulting signal attenuation before substitution.

Q: What does "Channel-to-Channel Matching (ΔRon)" mean? A: ΔRon specifies the maximum variation in on-state resistance between different channels within the same IC. MAX392ESE specifies 300mOhm matching, meaning all four channels maintain on-state resistance within 300mOhm of each other. This parameter is critical for applications requiring uniform signal attenuation across multiple channels.

Q: Are all substitute parts available in 16-SOIC packaging? A: Yes. All listed substitute parts use 16-SOIC (0.154", 3.90mm Width) surface mount packaging, maintaining PCB layout compatibility with MAX392ESE designs.

Q: What packaging options are available for substitute parts? A: MAX392ESE+ is available in Tube packaging. ADG442BRZ is available in Tube. ADG442BRZ-REEL is available in Cut Tape & Digi-Reel. ADG1312YRZ-REEL7 is available in Tape & Reel. ALD4202MSCL is available in Tube. DG455EY-T1-E3 is available in Tape & Reel. Select packaging based on production volume and handling requirements.

Q: Which substitute offers the best crosstalk performance? A: ADG442BRZ and ADG442BRZ-REEL offer the best crosstalk performance at -100dB @ 1MHz, compared to MAX392ESE at -85dB @ 1MHz. This 15dB improvement reduces signal coupling between channels, beneficial for precision analog applications.

Q: Can I use DG455EY-T1-E3 in a 3V supply application? A: No. DG455EY-T1-E3 requires minimum 12V single supply or ±5V dual supply. It is not compatible with the MAX392ESE's 3V minimum supply voltage. For 3V applications, use MAX392ESE+ or ALD4202MSCL.

Q: What is the inventory status of substitute parts? A: MAX392ESE+ has 1,103 pcs in stock. ADG442BRZ has 1,439 pcs. ADG442BRZ-REEL has 17,935 pcs (highest availability). ADG1312YRZ-REEL7 has 3,336 pcs. ALD4202MSCL has 757 pcs. DG455EY-T1-E3 has 1,670 pcs. All parts are listed as New Original In Stock.
