MAX4512CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4512CPE is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection and rail-to-rail signal handling. It operates with dual supplies from ±4.5V to ±18V or a single supply between +9V and +36V. The device provides four separately controlled switches with an on-resistance of 175Ω max and a match between channels of 10Ω max. Off-leakage current is 0.5nA at +25°C and 10nA at +85°C. The NO_ terminals are protected from overvoltage faults up to 36V during power-up or power-down. Logic inputs are compatible with TTL and CMOS standards.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs handle signals exceeding supply rails without damage
• Rail-to-rail signal handling capability for full voltage range operation
• Output clamped to appropriate supply voltage during fault conditions
• Pin-compatible with industry-standard non-protected switches

Analog Switches, Multiplexers, Demultiplexers Applications

• ATE equipment
• Data acquisition systems
• Industrial and process-control systems
• Avionics applications
• Redundant/backup systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The CPE suffix indicates a plastic DIP package with a commercial operating temperature range of 0°C to +70°C. Ensure compatibility with existing PCB footprints as these devices share pinouts with standard non-fault-protected counterparts. Confirm logic level requirements against the intended supply voltage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required on the NC_ or NO_ pins while maintaining low on-resistance. The MAX4512 specifically offers four normally open switches. Verify that the application does not require fault protection on the COM_ pin, as only the NO_ and NC_ pins are protected. Consider the ±40V fault protection limit when designing for high-voltage transients.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4512 belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches. While all three variants share identical electrical characteristics and pinouts, they differ in switch configuration: the MAX4511 has four normally closed switches, the MAX4512 has four normally open switches, and the MAX4513 combines two normally closed and two normally open switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

This device is pin-compatible with the DG411/DG412/DG413 and DG201/DG202/DG213 series. When replacing non-fault-protected switches, ensure that the COM_ pin connections do not exceed supply voltages, as these pins lack fault protection.
