MAX4664ESE Equivalent & Substitute Parts

Part Overview

The MAX4664ESE is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This component operates as a 1:1 multiplexer/demultiplexer with 4Ohm on-state resistance and is housed in a 16-SOIC surface mount package. The MAX4664ESE is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Substitute Categories:

Category 1: Direct Equivalent (Identical Electrical Specifications)

MAX4664ESE+ — Functionally identical to MAX4664ESE with identical electrical parameters. Differs only in packaging (Tube vs. unspecified) and product status (Active vs. Obsolete). RoHS3 compliant.

Category 2: Manufacturer-Recommended Substitutes (SPST-NC, Improved Performance)

ADG451BRZ, ADG451BRZ-REEL, ADG451BRZ-REEL7 — All variants of the ADG451 base product. These parts maintain SPST-NC circuit topology and 4-circuit configuration. On-state resistance increases to 5Ohm (1Ohm higher than MAX4664ESE), but channel-to-channel matching improves to 100mOhm. Supply voltage single (V+) is limited to 12V (narrower than MAX4664ESE's 4.5V ~ 36V range). Switch timing improves (180ns, 140ns vs. 275ns, 175ns). Crosstalk performance improves to -90dB @ 1MHz. All are RoHS3 compliant and Active status.

Category 3: Alternative Circuit Type (SPST-NO)

ADG452BRZ — Maintains 4-circuit configuration and 16-SOIC package but uses SPST-NO (Normally Open) circuit topology instead of SPST-NC. Electrical specifications match ADG451BRZ series. Suitable only for applications where normally-open switching behavior is acceptable.

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required): Select MAX4664ESE+ when identical electrical specifications and SPST-NC circuit topology are required. This part provides a direct functional equivalent with the advantage of Active product status and RoHS3 compliance, eliminating obsolescence risk while maintaining full electrical compatibility.

For New Designs or Redesigns (Performance Enhancement Acceptable): The ADG451BRZ series (ADG451BRZ, ADG451BRZ-REEL, ADG451BRZ-REEL7) offers improved performance characteristics including faster switch timing (180ns/140ns vs. 275ns/175ns), superior crosstalk performance (-90dB vs. -60dB @ 1MHz), and tighter channel-to-channel matching (100mOhm vs. 200mOhm). These improvements come with trade-offs: on-state resistance increases to 5Ohm, and single supply voltage is limited to 12V. All ADG451 variants maintain SPST-NC topology, 4-circuit configuration, 16-SOIC package, and Active product status with RoHS3 compliance. Selection among ADG451BRZ, ADG451BRZ-REEL, and ADG451BRZ-REEL7 depends on packaging requirements (Tube vs. Cut Tape & Digi-Reel).

For Normally-Open Applications: ADG452BRZ provides equivalent performance to the ADG451 series but with SPST-NO (Normally Open) circuit topology. This part is suitable only for applications where the switch default state must be open rather than closed.

Compliance Considerations: All substitute parts are RoHS3 compliant and carry Active product status, providing long-term supply assurance and regulatory compliance advantages over the obsolete, RoHS non-compliant MAX4664ESE.

Frequently Asked Questions (FAQ)

Q: Can MAX4664ESE+ be used as a direct drop-in replacement for MAX4664ESE? A: Yes. MAX4664ESE+ is electrically identical to MAX4664ESE across all specified parameters. The only differences are packaging format (Tube) and product status (Active vs. Obsolete). No circuit modifications are required.

Q: What are the key differences between MAX4664ESE and ADG451BRZ? A: Both maintain SPST-NC topology and 4-circuit configuration in 16-SOIC packages. ADG451BRZ offers improved performance: faster switching (180ns/140ns vs. 275ns/175ns), lower charge injection (20pC vs. 300pC), better crosstalk (-90dB vs. -60dB @ 1MHz), and tighter matching (100mOhm vs. 200mOhm). However, on-state resistance increases from 4Ohm to 5Ohm, and single supply voltage is limited to 12V instead of 4.5V ~ 36V.

Q: Are ADG451BRZ, ADG451BRZ-REEL, and ADG451BRZ-REEL7 electrically equivalent? A: Yes. All three variants have identical electrical specifications. They differ only in packaging format: ADG451BRZ is supplied in Tube, while ADG451BRZ-REEL and ADG451BRZ-REEL7 are supplied in Cut Tape & Digi-Reel format. Selection depends on your procurement and assembly requirements.

Q: When should ADG452BRZ be selected instead of ADG451BRZ? A: ADG452BRZ uses SPST-NO (Normally Open) circuit topology instead of SPST-NC. Select ADG452BRZ only if your application requires the switch to be open in its default state. All other electrical specifications match ADG451BRZ.

Q: Is the 1Ohm increase in on-state resistance (4Ohm to 5Ohm) significant for my application? A: This depends on your circuit design. The 1Ohm increase affects signal attenuation, power dissipation, and impedance matching. Review your signal path requirements and power budget. If the original 4Ohm specification is critical, MAX4664ESE+ is the appropriate choice.

Q: What is the impact of the narrower supply voltage range in ADG451BRZ (12V single supply vs. 4.5V ~ 36V)? A: ADG451BRZ single supply is fixed at 12V, eliminating the wide-range flexibility of MAX4664ESE. However, dual supply operation (±4.5V ~ 20V) remains available. If your design requires single supply voltages outside the 12V specification, MAX4664ESE+ must be used.

Q: Are all substitute parts RoHS compliant? A: Yes. MAX4664ESE+ and all ADG451/ADG452 variants are RoHS3 compliant. The original MAX4664ESE is RoHS non-compliant. For new designs or regulatory compliance requirements, select from the RoHS3 compliant alternatives.

Q: What is the inventory status for each part? A: MAX4664ESE has 7510 pcs in stock (Obsolete status). MAX4664ESE+ has 2900 pcs. ADG451BRZ has 1625 pcs. ADG451BRZ-REEL has 3013 pcs. ADG451BRZ-REEL7 has 15673 pcs (highest availability). ADG452BRZ has 5195 pcs. Inventory levels should be confirmed with your supplier for current availability.
