MAX334EPE+ Equivalent & Substitute Parts

Part Overview

The MAX334EPE+ 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 50Ohm on-state resistance and is housed in a 16-DIP package. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX334EPE+ is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Switch Circuit: SPST - NC (all substitutes must match)
• Number of Circuits: 4 (all substitutes must match)
• Multiplexer/Demultiplexer Ratio: 1:1 (all substitutes must match)
• Package / Case: 16-DIP (0.300", 7.62mm) (all substitutes must match)
• Mounting Type: Through Hole (all substitutes must match)
• Operating Temperature Range: -40°C ~ 85°C (all substitutes must match)

Performance Parameters (Allowed Variation):

• On-State Resistance (Max): Substitutes with equal or lower resistance are acceptable
• Voltage Supply Ranges: Substitutes must support the application's required voltage range
• Switch Time: Substitutes with equal or faster switching are acceptable
• Charge Injection: Lower values are preferred for signal integrity
• Channel Capacitance: Lower values are preferred for bandwidth
• Current - Leakage: Lower values are preferred for low-power applications
• Crosstalk: Lower magnitude (higher attenuation) is preferred

All four substitute parts meet the mandatory compatibility criteria and are available in active product status with current inventory.

Parameter Comparison

Engineering Selection Recommendations

ADG441BNZ (Analog Devices Inc.) Select this substitute when dual supply operation at ±15V is required and on-state resistance of 70Ohm is acceptable. This part offers improved charge injection (1pC) and reduced channel capacitance (4pF) compared to the MAX334EPE+. Single supply operation is limited to 12V. Current inventory: 2054 units.

DG271BCJ-E3 (Vishay Siliconix) Select this substitute for applications requiring matched on-state resistance (50Ohm) and dual supply operation at ±15V. This part delivers the fastest switching times (65ns Ton/Toff) and lowest charge injection (-5pC) among all substitutes. Single supply operation is not specified. Current inventory: 1148 units.

DG411DJ-E3 (Vishay Siliconix) Select this substitute for applications requiring the lowest on-state resistance (35Ohm) and extended single supply voltage range (5V ~ 44V). This part supports dual supply operation up to ±20V. Switching times are slower than the original part. Current inventory: 2549 units.

DG411DJZ (Renesas Electronics Corporation) Select this substitute for applications requiring the lowest on-state resistance (35Ohm), extended single supply voltage range (5V ~ 44V), and lowest leakage current (100pA). This part supports dual supply operation up to ±20V. Switching times are slower than the original part. Current inventory: 12193 units.

All substitutes are ROHS3 compliant and MSL 1 rated. Selection should be based on specific voltage supply requirements, on-state resistance tolerance, and switching speed constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitutes as a direct replacement for MAX334EPE+? A: All four substitutes are functionally compatible in terms of circuit topology (SPST-NC, 4 circuits, 1:1 configuration) and package (16-DIP through-hole). However, electrical performance differs. Verify that your application can tolerate the specific on-state resistance, switching time, and voltage supply characteristics of the chosen substitute.

Q: What is the key difference between DG411DJ-E3 and DG411DJZ? A: Both parts are identical in electrical specifications and package. The primary difference is the manufacturer: DG411DJ-E3 is from Vishay Siliconix, while DG411DJZ is from Renesas Electronics Corporation. DG411DJZ has significantly higher inventory availability (12193 units vs. 2549 units).

Q: Which substitute has the best performance for low-noise applications? A: DG271BCJ-E3 offers the lowest charge injection (-5pC) and fastest switching times (65ns), making it optimal for low-noise signal switching. ADG441BNZ also provides excellent charge injection performance (1pC) with reduced channel capacitance (4pF).

Q: Are all substitutes RoHS compliant? A: Yes, all four substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the MAX334EPE+.

Q: What voltage supply options do I have with each substitute? A: ADG441BNZ is limited to 12V single supply or ±15V dual supply. DG271BCJ-E3 supports ±15V dual supply only. DG411DJ-E3 and DG411DJZ both support 5V ~ 44V single supply or ±5V ~ 20V dual supply, offering the widest voltage flexibility.

Q: Which substitute should I choose if on-state resistance is critical? A: DG411DJ-E3 and DG411DJZ both offer the lowest on-state resistance at 35Ohm. DG271BCJ-E3 matches the original 50Ohm specification. ADG441BNZ has the highest on-state resistance at 70Ohm.
