Substitute Part Grouping Explanation
Substitute parts for the MAX4665CSE+ are identified based on the following critical parameters that define functional equivalence:
- Switch Architecture: SPST-NO topology with 4-circuit configuration and 1:1 multiplexer/demultiplexer function
- Package Compatibility: 16-SOIC surface mount package with identical 0.154" (3.90mm) width
- On-State Resistance: Maximum 4Ohm to 5Ohm range acceptable for signal switching applications
- Supply Voltage Range: Compatibility with dual supply operation (±4.5V ~ 20V) and single supply operation
- Switching Performance: Switch time and charge injection characteristics suitable for analog signal routing
- Leakage Current: Maximum 500pA specification maintained across substitutes
- Compliance: ROHS3 compliance and MSL Level 1 rating required
The ADG452BRZ, ADG452BRZ-REEL, and ADG452BRZ-REEL7 variants meet these substitution criteria. These parts differ primarily in packaging format (Tube, Tape & Reel, and Cut Tape & Digi-Reel respectively) and feature slightly higher on-state resistance (5Ohm maximum) with improved performance in crosstalk (-90dB @ 1MHz) and extended operating temperature range (-40°C ~ 85°C).

Engineering Selection Recommendations
All substitute parts listed maintain active product status with ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility with the MAX4665CSE+.
The ADG452 series variants offer improved electrical performance characteristics including faster switching times (180ns/140ns versus 275ns/175ns), significantly lower charge injection (20pC versus 300pC), and superior crosstalk isolation (-90dB versus -60dB @ 1MHz). These enhancements make the ADG452 series suitable for applications requiring higher signal fidelity and lower distortion in analog switching circuits.
Selection between ADG452BRZ, ADG452BRZ-REEL, and ADG452BRZ-REEL7 is determined by packaging and supply chain requirements rather than electrical performance, as all three variants share identical electrical specifications. The Tube format (ADG452BRZ) supports manual assembly and small-volume applications. The Tape & Reel format (ADG452BRZ-REEL) accommodates high-speed automated pick-and-place assembly. The Cut Tape & Digi-Reel format (ADG452BRZ-REEL7) provides flexibility for mixed-volume production environments.
Frequently Asked Questions (FAQ)
Q: Can ADG452BRZ directly replace MAX4665CSE+ in existing designs?
A: Yes. Both parts share identical 16-SOIC package geometry, SPST-NO 4-circuit architecture, and 1:1 multiplexer/demultiplexer configuration. The ADG452BRZ operates within the same dual supply voltage range (±4.5V ~ 20V) and maintains equivalent leakage current specifications (500pA maximum). The 1Ohm increase in on-state resistance (5Ohm versus 4Ohm) is within acceptable tolerance for most analog switching applications.
Q: What are the performance advantages of ADG452 variants over MAX4665CSE+?
A: The ADG452 series provides faster switching response (180ns/140ns versus 275ns/175ns), substantially lower charge injection (20pC versus 300pC), and improved crosstalk performance (-90dB versus -60dB @ 1MHz). These characteristics reduce signal distortion and settling time in precision analog signal routing applications. The ADG452 series also supports an extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C).
Q: Are packaging format differences between ADG452BRZ, ADG452BRZ-REEL, and ADG452BRZ-REEL7 electrically significant?
A: No. All three variants contain identical die and electrical specifications. Packaging differences (Tube, Tape & Reel, and Cut Tape & Digi-Reel) affect only supply chain logistics, assembly automation compatibility, and inventory management. Electrical performance and functional behavior are identical across all three formats.
Q: What supply voltage configurations are supported by substitute parts?
A: All substitute parts support dual supply operation (±4.5V ~ 20V). The ADG452BRZ additionally specifies single supply operation at 12V. The MAX4665CSE+ supports broader single supply range (4.5V ~ 36V). For applications requiring single supply voltages outside the 12V specification, the MAX4665CSE+ remains the appropriate selection.
Q: Are all parts compliant with current environmental and regulatory standards?
A: Yes. All parts listed maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, confirming compatibility with current manufacturing and environmental regulations.
