MAX338ESE 8:1 Analog Multiplexer IC — Equivalent & Substitute Parts

Part Overview

The MAX338ESE is an 8:1 analog multiplexer IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-SOIC surface mount package. This interface component features a 400Ω on-state resistance and supports both single supply (4.5V to 30V) and dual supply (±4.5V to ±20V) configurations. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across multiplexer topology, package form factor, and electrical operating ranges while meeting modern compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX338ESE is determined by strict adherence to the following criteria:

Primary Substitution Criteria:

• Multiplexer topology: 8:1 configuration (mandatory)

• Operating temperature: Minimum -40°C to maximum 85°C or higher
• RoHS3 compliance status (preferred for modern designs)

Substitute Parts Identified:

Direct Packaging Equivalent:

• MAX338ESE+ (Tube packaging, Active status, RoHS3 compliant)

Lower On-State Resistance Substitutes (100Ω–210Ω range):

• ADG1208YRZ (200Ω, Active, RoHS3)
• ADG1208YRZ-REEL7 (200Ω, Active, RoHS3)
• ADG1308BRZ-REEL7 (210Ω, Active, RoHS3)
• DG408DY-E3 (100Ω, Active, RoHS3)
• DG408DY-T1-E3 (100Ω, Active, RoHS3)

Matched On-State Resistance Substitute (380Ω range):

• DG508BEY-T1-E3 (380Ω, Active, RoHS3)

Higher On-State Resistance Substitute (1.8kΩ range):

• HI9P0548-5Z (1.8kΩ, Active, RoHS3)
• HI9P0548-5Z96 (1.8kΩ, Active, RoHS3)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): MAX338ESE+ is the active equivalent with identical electrical specifications and RoHS3 compliance. This part maintains the 400Ω on-state resistance and full supply voltage range of the original obsolete part while providing modern compliance certification.

For Lower On-State Resistance Applications (100Ω–210Ω): ADG1208YRZ, ADG1208YRZ-REEL7, ADG1308BRZ-REEL7, DG408DY-E3, and DG408DY-T1-E3 offer reduced on-state resistance with improved switching performance. These parts are suitable when lower channel resistance is acceptable or beneficial. All are RoHS3 compliant and active production status. The ADG series (Analog Devices) provides tighter channel matching and lower charge injection. The DG408 series (Vishay Siliconix) offers extended single supply voltage range to 36V.

For Matched On-State Resistance (380Ω): DG508BEY-T1-E3 provides near-identical on-state resistance (380Ω) with extended operating temperature to 125°C and RoHS3 compliance. This part is suitable for applications requiring minimal resistance deviation from the original specification.

For Dual Supply Only Applications (±15V): HI9P0548-5Z and HI9P0548-5Z96 (Renesas Electronics) are suitable only for dual supply configurations with ±15V operation. These parts feature significantly higher on-state resistance (1.8kΩ) and narrower operating temperature range (0°C–75°C), limiting their applicability to specific low-frequency, dual-supply-only designs.

Compliance Consideration: All substitute parts listed are RoHS3 compliant and active production status, addressing the obsolescence and non-compliance status of the original MAX338ESE.

Frequently Asked Questions (FAQ)

Q: Can MAX338ESE+ be used as a direct drop-in replacement for MAX338ESE? A: Yes. MAX338ESE+ maintains identical electrical specifications including 400Ω on-state resistance, supply voltage ranges (4.5V–30V single, ±4.5V–±20V dual), and 16-SOIC package form factor. The primary differences are active production status and RoHS3 compliance.

Q: What is the functional difference between the ADG1208 and DG408 series substitutes? A: ADG1208 (Analog Devices) features 200Ω on-state resistance with tighter channel matching (4.6Ω) and lower charge injection (0.4pC), optimized for precision analog switching. DG408 (Vishay Siliconix) features 100Ω on-state resistance with extended single supply range to 36V, optimized for lower impedance applications. Both are 8:1 multiplexers in 16-SOIC packages.

Q: Are the ADG1208YRZ and ADG1208YRZ-REEL7 electrically identical? A: Yes, electrically identical. The difference is packaging: ADG1208YRZ is supplied in Tube packaging, while ADG1208YRZ-REEL7 is supplied in Cut Tape and Digi-Reel format. Select based on procurement and assembly requirements.

Q: Can DG508BEY-T1-E3 replace MAX338ESE in all applications? A: DG508BEY-T1-E3 is suitable for applications where the 380Ω on-state resistance is acceptable and single supply minimum voltage of 12V is met. It offers extended temperature range (-40°C–125°C) and improved crosstalk performance (-88dB @ 1MHz). Verify supply voltage compatibility before selection.

Q: Why do HI9P0548-5Z parts have significantly higher on-state resistance? A: HI9P0548-5Z is designed for dual supply only (±15V) applications and features 1.8kΩ on-state resistance. This higher resistance is characteristic of the Renesas design and limits applicability to low-frequency, low-current switching scenarios. Not suitable for general-purpose replacement of MAX338ESE.

Q: What is the impact of lower on-state resistance in ADG1208 and DG408 substitutes? A: Lower on-state resistance (100Ω–200Ω vs. 400Ω) reduces signal attenuation and improves bandwidth performance. This is beneficial for high-frequency and precision applications. Verify that the application circuit can tolerate the reduced resistance without affecting signal integrity or power dissipation characteristics.

Q: Are all substitute parts available in 16-SOIC package? A: Yes, all substitute parts listed are available in 16-SOIC (0.154", 3.90mm Width) surface mount package, maintaining mechanical compatibility with MAX338ESE PCB layouts.

Q: What is the operating temperature consideration when selecting a substitute? A: MAX338ESE operates -40°C–85°C. Most substitutes extend this range to -40°C–125°C (ADG1208, ADG1308, DG508) or maintain -40°C–85°C (DG408). HI9P0548 operates 0°C–75°C, which is narrower. Select based on application temperature requirements.
