MAX4712EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712EPE is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection and rail-to-rail signal handling. It operates from a single +2.7V to +11V supply or dual ±2.7V to ±5.5V supplies. The device provides low on-resistance with a maximum of 25Ω at +25°C and guaranteed flatness over the signal range. Switching times are less than 125ns for turn-on and 80ns for turn-off. Digital inputs have +0.8V to +2.4V logic thresholds, ensuring TTL and CMOS compatibility. The E suffix indicates an operating temperature range of -40°C to +85°C, housed in a 16-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature grade. Confirm availability status through authorized distributors as component lifecycles may change. Ensure the selected variant matches the required thermal and physical specifications for the target application design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring fault protection on analog inputs while maintaining low on-resistance. Verify that the supply voltage range aligns with the system requirements, noting the difference in performance between single and dual supply configurations. Consider the 16-pin Plastic DIP package constraints regarding board space and thermal dissipation capabilities during the design phase.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. The MAX4712 specifically contains four normally open switches, distinguishing it from the MAX4711 which features normally closed switches. All variants share identical pinouts and core electrical characteristics, facilitating direct substitution in existing designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with the MAX391, MAX392, and MAX393 series. Designers should verify that the non-fault-protected nature of the COM_ pins in legacy parts does not conflict with the fault-protection behavior of the NO_/NC_ pins in this device.
