MAX4711CUE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4711CUE is a quad single-pole/single-throw (SPST) analog switch in a 16-pin TSSOP package. It operates from a single +2.7V to +11V supply or dual ±2.7V to ±5.5V supplies. The device features fault protection allowing inputs to exceed supply rails without excessive current draw. Key electrical parameters include a maximum on-resistance of 25Ω at +25°C, an on-resistance match between channels of 1Ω, and turn-on/turn-off times under 125ns and 80ns respectively. The commercial temperature range is 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected analog inputs prevent excessive current draw when signals exceed supply rails.
• Rail-to-rail signal handling capability with low on-resistance.
• TTL and CMOS logic compatibility across specified supply ranges.
• All switches automatically turn off when power is removed.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C). Confirm the 'UE' suffix corresponds to the 16-pin TSSOP package. Ensure the order matches the exact pinout for the MAX4711 variant, which contains four normally closed switches.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring rail-to-rail signal switching with fault protection. Verify that the required on-resistance flatness and leakage currents meet system specifications. Consider the MAX4712 or MAX4713 if normally open or mixed configurations are needed instead of the standard NC configuration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX471x family of fault-protected, low-voltage analog switches. It shares pinouts with industry-standard MAX391/MAX392/MAX393 devices but adds fault protection features. The C suffix denotes the commercial grade temperature range, while E would indicate extended range.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include MAX391, MAX392, and MAX393. Note that these alternatives lack the fault-protection feature found in the MAX4711 series. Direct substitution requires verifying that the absence of fault protection does not compromise circuit safety.

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 the COM_ pin will be clamped by internal diodes, potentially causing high currents.

What is the fault voltage limit with power off?

The NO_ and NC_ pins can withstand up to ±12V even when the power supplies are removed.

How does the device behave during a fault condition?

When an input exceeds the supply rails, the switch turns itself off, and the output is clamped to the same polarity supply as the input signal.
