PS4066AEEE Equivalent & Substitute Parts

Part Overview

The PS4066AEEE is a 4-circuit SPST-NO IC switch manufactured by Diodes Incorporated, designed for interface applications requiring low on-state resistance and high-speed switching. This part operates across a 3V to 16V supply range with 45Ohm on-state resistance and 100MHz bandwidth capability. The PS4066AEEE is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across switching characteristics, impedance specifications, and thermal operating ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the PS4066AEEE is determined by the following critical parameters:

Electrical Compatibility Requirements:

Switch circuit type: SPST - NO (4 circuits, 1:1 configuration)
On-state resistance: 45Ohm maximum
Channel-to-channel matching: 500mOhm
Switching speed: 100ns (Ton), 75ns (Toff) maximum
Bandwidth: 100MHz minimum
Crosstalk: -86dB @ 1MHz minimum
Package: 16-SSOP (0.154", 3.90mm Width)

Supply Voltage Compatibility: The PS4066AEEE operates at 3V to 16V single supply. Substitute parts must support this voltage range or a compatible subset. Parts with 2V to 16V supply range are compatible as they encompass the PS4066AEEE operating window.

Thermal Operating Range: The PS4066AEEE operates from -40°C to 85°C. Substitute parts with narrower temperature ranges (0°C to 70°C) are compatible for applications within that reduced range.

Packaging and Compliance: All substitute parts are available in 16-QSOP packaging (equivalent to 16-SSOP). RoHS3 compliance status differs between the obsolete PS4066AEEE and active substitute parts from Analog Devices Inc./Maxim Integrated.

Engineering Selection Recommendations

Primary Substitutes for Full Temperature Range (-40°C to 85°C):

MAX4066AEEE+ and MAX4066AEEE+T are direct electrical and thermal equivalents to the PS4066AEEE. Both parts maintain the -40°C to 85°C operating temperature range and are available in active product status with ROHS3 compliance. Selection between these two depends on packaging requirements: MAX4066AEEE+ is supplied in Tube packaging, while MAX4066AEEE+T is supplied in Tape & Reel format for automated assembly.

Secondary Substitutes for Commercial Temperature Range (0°C to 70°C):

MAX4066ACEE+, MAX4066ACEE+T, MAX4066CEE+, and MAX4066CEE+T are electrically compatible with the PS4066AEEE but operate within a narrower temperature range of 0°C to 70°C. These parts are suitable for applications that do not require extended low-temperature operation below 0°C or high-temperature operation above 70°C. MAX4066CEE+ and MAX4066CEE+T exhibit slightly higher leakage current (1nA maximum) compared to other substitutes (100pA maximum), which may be relevant for low-power or high-impedance applications.

Packaging Considerations:

All substitute parts are available in both Tube and Tape & Reel packaging formats. Tube packaging is appropriate for manual assembly and lower-volume applications. Tape & Reel packaging is standard for high-volume automated manufacturing processes.

Compliance Status:

All Analog Devices/Maxim substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory advantages over the obsolete, non-compliant PS4066AEEE.

Frequently Asked Questions (FAQ)

Q: Can MAX4066ACEE+ replace PS4066AEEE in all applications?

A: MAX4066ACEE+ is electrically equivalent but operates within 0°C to 70°C temperature range. It is suitable for applications within this range. If your application requires operation below 0°C or above 70°C, use MAX4066AEEE+ or MAX4066AEEE+T instead.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging contains loose components suitable for manual assembly and small-quantity applications. Tape & Reel packaging presents components on continuous tape for automated pick-and-place assembly equipment, standard for high-volume production.

Q: Are all substitute parts pin-compatible with PS4066AEEE?

A: Yes. All substitute parts use the same 16-SSOP package with identical pinout and electrical interface specifications.

Q: Why do MAX4066CEE+ and MAX4066CEE+T have higher leakage current?

A: MAX4066CEE+ and MAX4066CEE+T specify 1nA maximum leakage current compared to 100pA for other substitutes. This difference is within the same device family and reflects manufacturing process variations. For applications sensitive to leakage current, select MAX4066ACEE+, MAX4066ACEE+T, MAX4066AEEE+, or MAX4066AEEE+T.

Q: What is charge injection and why is it lower in substitute parts?

A: Charge injection is the amount of charge transferred to the signal path when the switch transitions. The PS4066AEEE specifies 2pC maximum, while Analog Devices/Maxim substitutes specify 1pC maximum. Lower charge injection reduces signal distortion in precision analog applications. All parts meet the switching speed and bandwidth requirements.

Q: Can I use MAX4066AEEE+ in designs originally specified for PS4066AEEE?

A: Yes. MAX4066AEEE+ is a direct functional and thermal equivalent with identical electrical specifications and operating temperature range. It is the recommended primary substitute for new designs and production transitions.

Q: Are there inventory considerations for substitute selection?

A: Current inventory levels vary by part number and packaging format. MAX4066ACEE+ has the highest inventory (2200 pcs), followed by MAX4066CEE+ (1254 pcs) and MAX4066AEEE+ (1302 pcs). Availability should be confirmed with your supplier for production planning.
