MAX4712CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712CSE+ 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 specified signal range. Switching times are less than 125ns for turn-on and less than 80ns for turn-off. Digital inputs have logic thresholds ensuring TTL and CMOS compatibility. The NO_ and NC_ pins are fault-protected up to ±12V, while COM_ pins are not.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific suffix indicates lead-free status and compliance with RoHS directives. Ensure the package type matches the required board layout specifications. Cross-reference the ordering information in the datasheet to validate availability and correct part identification before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection on analog inputs is required alongside low-voltage operation. Verify that the single-supply or dual-supply configuration aligns with the system power architecture. Consider the on-resistance and switching speed requirements relative to the application bandwidth. Ensure the logic input levels match the controlling microcontroller or FPGA outputs.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. The MAX4712 variant specifically contains four normally open switches. It is pin-compatible with industry-standard MAX391/MAX392/MAX393 devices, facilitating direct replacement in existing designs requiring enhanced fault protection capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4712CSE is pin-compatible with the MAX391, MAX392, and MAX393 series. When replacing non-fault-protected switches, verify that the COM_ pins do not exceed supply voltages as they lack internal fault protection.
