MAX4533CPP+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4533CPP+ is a quad, single-pole/double-throw (SPDT) analog switch featuring fault protection and rail-to-rail signal handling. It operates from dual ±4.5V to ±18V supplies or a single +9V to +36V supply. The device provides ±25V fault protection with power on and ±40V with power off. On-resistance is 175Ω maximum at ±15V supplies, matched between channels to 10Ω maximum. Off-leakage current is 0.5nA at +25°C and 10nA at +85°C. Logic inputs are TTL/CMOS compatible with thresholds of +0.8V and +2.4V. It is housed in a 20-pin Plastic DIP package and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CPP+ corresponds to the 20-pin Plastic DIP package and the 0°C to +70°C industrial temperature grade. Confirm that the component meets RoHS compliance standards as indicated by the plus sign in the part number. Ensure the ordering documentation matches the manufacturer's official specifications for this exact variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required for signals exceeding supply rails. It is suitable for applications needing rail-to-rail signal handling without transition glitches during faults. Consider the 175Ω maximum on-resistance and 0.5nA leakage current for precision requirements. Verify compatibility with existing PCB footprints designed for MAX333/MAX333A pinouts.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4533 series includes variants like MAX4533EAP+ and MAX4533CWP+ offering different packages and temperature ranges. The MAX4533CPP+ specifically denotes the plastic DIP package option. This family is designed for high-reliability analog switching where overvoltage conditions must be managed safely.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other MAX4533 variants such as MAX4533EPP+ or MAX4533MJP+ if temperature or package differences are acceptable. Cross-reference with MAX333/MAX333A equivalents for pin-compatible replacements in existing designs.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the fault protection voltage limit with power off?

The NO_ and NC_ terminals are protected from overvoltage faults up to ±40V with power off.

How does the MAX4533 handle fault conditions?

During a fault, NO_ and NC_ become high impedance, and the output (COM_) clamps to the appropriate polarity supply rail, providing up to ±10mA of load current.

Is the MAX4533CPP+ compatible with TTL logic?

Yes, all digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply.
