Engineering Selection Recommendations

The ADG333ABNZ is the direct substitute for the MAX333CPP+ based on the following engineering criteria:

Mechanical Compatibility: Both components utilize identical 20-DIP (0.300", 7.62mm) through-hole packaging, enabling direct PCB footprint compatibility without layout modifications.

Electrical Compatibility: The ADG333ABNZ maintains the same SPDT 2:1 multiplexer/demultiplexer configuration with 4 circuits, ensuring functional equivalence in signal routing applications. The substitute part supports the full voltage range required by MAX333CPP+ applications while extending operational capability to lower supply voltages (3V single supply, ±3V dual supply).

Regulatory Compliance: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Product Lifecycle: The ADG333ABNZ is actively manufactured by Analog Devices Inc., ensuring long-term availability, technical support, and supply chain continuity. The MAX333CPP+ obsolete status necessitates transition to the ADG333ABNZ for new designs and ongoing system support.

Performance Enhancement: The ADG333ABNZ provides measurable improvements in on-state resistance (45Ohm vs. 250Ohm), switching speed (90ns/80ns vs. 1µs/500ns), leakage current (250pA vs. 5nA), and crosstalk isolation (-85dB vs. -78dB), making it suitable for applications requiring enhanced signal integrity and reduced power consumption.

Frequently Asked Questions (FAQ)

Q: Is the ADG333ABNZ a direct pin-for-pin replacement for the MAX333CPP+?

A: Yes. Both components use identical 20-DIP (0.300", 7.62mm) through-hole packaging with matching pin configurations. No PCB modifications are required for substitution.

Q: What are the key electrical differences between these parts?

A: The ADG333ABNZ provides superior performance across multiple parameters: on-state resistance is reduced from 250Ohm to 45Ohm, switching time is improved from 1µs/500ns to 90ns/80ns (typical), leakage current is reduced from 5nA to 250pA, and crosstalk isolation is enhanced from -78dB to -85dB at 1MHz.
