MAX4712CUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4712CUE+ 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 guarantees on-resistance 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 +0.8V to +2.4V logic thresholds, ensuring TTL and CMOS compatibility. The component is housed in a 16-TSSOP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' against the datasheet ordering information to confirm the commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the 16-TSSOP package dimensions match the design constraints. Cross-reference the manufacturer's latest documentation for any potential obsolescence notices or lifecycle changes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required for analog signals exceeding supply rails. Verify that the 25Ω maximum on-resistance meets the application's signal integrity requirements. Ensure the logic input thresholds align with the system's microcontroller or driver voltage levels. Consider the 16-TSSOP package size for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4711/MAX4712/MAX4713 family of fault-protected, low-voltage analog switches. The MAX4712 variant specifically features four normally open switches, distinguishing it from the MAX4711 (normally closed) and MAX4713 (mixed configuration). These devices are pin-compatible with industry-standard MAX391/MAX392/MAX393 switches, facilitating direct replacements in existing designs.

Analog Switches, Multiplexers, Demultiplexers FAQ

Are the COM_ pins fault-protected?

No, the COM_ pins are not fault-protected. They act as normal CMOS switch terminals, and signals exceeding the supply voltages may cause high currents through internal ESD diodes.

What is the fault protection voltage range with power off?

The NO_ and NC_ pins provide ±12V fault protection even when the power supplies are removed.

How does the device behave during a positive fault condition?

When the signal exceeds V+ by about 150mV, the input becomes high impedance, and if the switch is on, clamp FETs source current from V+ to the COM_ output, clamping it to the positive supply rail.
