MAX4513CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4513CPE is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection and rail-to-rail signal handling. It integrates two normally closed and two normally open switches within a 16-pin plastic DIP package. The device operates with dual supplies from ±4.5V to ±18V or a single supply between +9V and +36V. On-resistance is typically 200Ω max at ±15V, with channel matching of 10Ω max. Fault-protected inputs handle signals up to ±36V during operation and ±40V when powered off. Logic thresholds support TTL and CMOS compatibility.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected NO_ and NC_ terminals withstand overvoltage faults up to ±36V during power-on and ±40V during power-off conditions.
• Rail-to-rail signal handling capability ensures unambiguous outputs by clamping the COM_ terminal to the appropriate supply voltage during faults without transition glitches.
• Pin-compatible with industry-standard non-protected switches such as DG201/DG202/DG213 and DG411/DG412/DG413 for direct board replacements.
• TTL- and CMOS-compatible logic inputs allow operation with single +9V to +15V or ±15V supplies without requiring power-supply sequencing.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE' corresponds to the 0°C to +70°C commercial temperature range and the 16-pin Plastic DIP package configuration. Confirm that the ordering code matches the exact pinout requirements for your PCB footprint, as this component is designed to be pin-compatible with legacy DG series switches but requires careful evaluation of fault protection differences.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4513 variant specifically because it contains two normally closed and two normally open switches, unlike the MAX4511 (all NC) or MAX4512 (all NO). Ensure the application requires fault protection on the input terminals rather than just the output. Verify that the required on-resistance and leakage current specifications are met within the intended operating temperature range of -40°C to +85°C if higher performance is needed.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches manufactured by Analog Devices Inc./Maxim Integrated. The family shares identical pinouts and core fault-protection architecture, differing only in the internal configuration of normally open versus normally closed switches. The MAX4513 provides a mixed configuration suitable for applications requiring both states within a single package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4511 and MAX4512, though their switch configurations differ. Legacy equivalents such as the DG201, DG202, DG213, DG411, DG412, and DG413 share the same pinout but lack the integrated fault protection features found in the MAX4513 series.

Analog Switches, Multiplexers, Demultiplexers FAQ

Which pins on the MAX4513 are fault protected?

Only the NO_ (Normally Open) and NC_ (Normally Closed) terminals are fault protected. The COM_ (Common) and IN_ (Input) pins are not fault protected and must not exceed the supply voltages V+ or V-.

How does the MAX4513 behave during a fault condition?

During a fault where the NO_ or NC_ voltage exceeds the supply rails, the switch input becomes high impedance. The COM_ output is clamped to the appropriate supply voltage (V+ or V-) and can source or sink up to 10mA to maintain the load voltage.

What is the maximum fault voltage when the device is powered off?

When power is removed (V+ = V- = 0), the NO_ and NC_ terminals can withstand fault voltages up to ±40V while remaining in a virtual open circuit state.
