MAX4711EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4711EPE is a quad, single-pole/single-throw (SPST) analog switch in a 16-pin Plastic DIP package. It operates from a single +2.7V to +11V supply or dual ±2.7V to ±5.5V supplies. The device features fault protection on NO_ and NC_ pins up to ±12V with power off. On-resistance is typically 16Ω at +25°C with dual supplies. Turn-on time is max 125ns and turn-off time is max 80ns. Leakage current is typically ±10nA. Logic inputs are TTL and CMOS compatible.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EPE confirms the -40°C to +85°C temperature range and 16-pin Plastic DIP package. Confirm RoHS compliance status as older Maxim Integrated parts may vary. Check for obsolescence notices since Analog Devices acquired Maxim Integrated. Ensure pinout matches target PCB footprint before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring fault protection on analog inputs while maintaining rail-to-rail signal integrity. Verify that the required on-resistance flatness meets system accuracy needs. Consider the 16-pin DIP package constraints for board layout. Ensure logic voltage thresholds align with the driving microcontroller or FPGA outputs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4711 variant specifically contains four normally closed (NC) switches. It belongs to the MAX4711-MAX4713 family of fault-protected, low-voltage analog switches. This series is designed to replace standard CMOS switches where input overvoltage protection is critical. The E suffix denotes the extended industrial temperature range.

Analog Switches, Multiplexers, Demultiplexers FAQ

Are the COM_ pins fault-protected?

No, the COM_ pins are not fault-protected. Signals exceeding V+ or V- on COM_ will be clamped by internal diodes.

What is the maximum fault voltage allowed on the inputs?

The NO_ and NC_ pins can withstand up to ±12V relative to ground, regardless of the supply voltage, even when power is off.

How does the device behave during a fault condition?

During a fault, the switch turns itself off, and the output is clamped to the same polarity supply as the input signal, preventing voltages beyond the supply rails.
