MAX4617EEE Equivalent & Substitute Parts

Part Overview

The MAX4617EEE is an 8:1 analog multiplexer/switch IC manufactured by Analog Devices Inc./Maxim Integrated, designed for signal routing and switching applications. This part features a single 8:1 multiplexer circuit with 10Ω on-state resistance in a 16-QSOP surface mount package. The MAX4617EEE is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain functional compatibility through equivalent multiplexer topology, compatible supply voltage ranges, and suitable on-state resistance characteristics for the target application.

Substitute Part Grouping Explanation

Substitute parts for the MAX4617EEE are grouped based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

Multiplexer topology: 8:1 configuration with single circuit
Package type: 16-TSSOP or equivalent surface mount (0.173" width, 4.40mm)
Supply voltage overlap: Minimum 2V to 5.5V range or compatible subset
On-state resistance: Acceptable range depends on application impedance requirements

Substitution Logic: Substitute parts are organized into three functional groups based on on-state resistance characteristics and supply voltage specifications. Group 1 (low resistance: 25–210Ω) suits applications requiring minimal signal attenuation and operates across 2–6V supplies. Group 2 (medium resistance: 400–750mΩ) provides moderate impedance with extended temperature or low-voltage operation. All substitutes maintain 8:1 multiplexer topology, single-circuit configuration, and 16-TSSOP packaging. Product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant) are secondary selection factors based on supply chain and regulatory requirements.

Engineering Selection Recommendations

For Direct Replacement (2–5.5V Supply Range): The MC74LVX8051DTR2G, MC74LVX8051DTG, and MC74LVXT8051DTRG (onsemi) provide the closest functional match to the MAX4617EEE within the original supply voltage envelope. These parts maintain 8:1 multiplexer topology, 16-TSSOP packaging, and active product status with ROHS3 compliance. The 25Ω on-state resistance is higher than the original 10Ω specification but remains suitable for most signal-routing applications. Extended operating temperature range (−55 to +85°C) provides additional margin.

For 4.5–5.5V TTL-Compatible Applications: The 74HCT4851PW,118 and 74HCT4851PW-Q100,1 (Nexperia) are optimized for TTL-level supply voltages. The automotive-qualified variant (74HCT4851PW-Q100,1) includes AEC-Q100 certification for automotive applications. Both maintain active status and ROHS3 compliance with extended temperature operation to +125°C.

For Low-Voltage Applications (1.6–3.6V): The ISL84781IVZ and ISL84781IVZ-T (Renesas) support reduced supply voltages down to 1.6V with 0.75Ω on-state resistance and superior channel matching (120mΩ). These parts are suitable for battery-powered or low-voltage logic systems requiring minimal signal attenuation.

For General-Purpose 2–6V Operation: The 74HC4851PW,118 (Nexperia) and MC74HC4851ADTR2G (onsemi) provide broad supply voltage compatibility across 2–6V with active product status and ROHS3 compliance. The MC74HC4851ADTR2G extends operating temperature to −55°C for industrial applications.

All recommended substitutes are currently in active production with ROHS3 compliance, eliminating the regulatory and supply-chain constraints associated with the obsolete MAX4617EEE.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MAX4617EEE with any of these substitutes without circuit modification?

A: Functional replacement depends on on-state resistance tolerance and supply voltage requirements. Parts with 25–210Ω on-state resistance are suitable for most signal-routing applications where the original 10Ω specification is not critical. Verify that your application's impedance budget accommodates the substitute part's Ron value. Supply voltage compatibility must be confirmed; parts rated for 4.5–5.5V (74HCT series) require TTL-level supplies and are not compatible with 2V minimum supplies.

Q: What is the difference between 74HC4851 and 74HCT4851?

A: The 74HC4851 operates across 2–6V supply range with higher on-state resistance (195Ω). The 74HCT4851 is optimized for TTL-compatible 4.5–5.5V supplies with slightly higher on-state resistance (210Ω) and faster switching times. Choose 74HC4851 for flexible supply voltage applications; choose 74HCT4851 for TTL-level systems.

Q: Are all substitutes available in the same package as MAX4617EEE?

A: The MAX4617EEE uses 16-QSOP packaging. All listed substitutes use 16-TSSOP packaging (0.173" width, 4.40mm), which is mechanically and electrically compatible for PCB layout purposes. Pin assignments are identical across all 8:1 multiplexer variants listed.

Q: Which substitute offers the lowest on-state resistance?

A: The ISL84781IVZ and ISL84781IVZ-T (Renesas) and NX3L4051PW-Q100J (NXP) offer 0.75Ω on-state resistance, closest to the original 10Ω specification. However, these parts operate at reduced supply voltages (1.6–3.6V for ISL84781; 1.4–4.3V for NX3L4051) and are suitable only for low-voltage applications.

Q: What is the temperature operating range difference, and does it matter?

A: The MAX4617EEE operates −40 to +85°C. Most active substitutes extend to −40 to +125°C, providing additional thermal margin for industrial and automotive applications. The MC74LVX8051 series operates −55 to +85°C, extending the lower temperature limit for extreme environments. Select based on your application's thermal requirements.

Q: Are these parts RoHS compliant?

A: The MAX4617EEE is RoHS non-compliant. All active substitutes listed are ROHS3 compliant, meeting current environmental regulations for new designs and production.

Q: Which substitute is best for automotive applications?

A: The 74HCT4851PW-Q100,1 (Nexperia) and NX3L4051PW-Q100J (NXP) carry AEC-Q100 automotive qualification. Both maintain active status, ROHS3 compliance, and extended operating temperature ranges suitable for automotive environments.
