Product details
Overview
The MAX4511ESE+T from Maxim Integrated is a quad, normally closed (NC), fault-protected SPST analog switch with rail-to-rail signal handling, ±36V fault protection on NC/NO terminals, 175Ω max on-resistance at ±15V supplies, and operation across ±4.5V to ±18V dual or +9V to +36V single supply. It serves in industrial data acquisition systems where overvoltage transients during power-up/down must not disrupt signal integrity or damage downstream circuitry.
For engineers reviewing the MAX4511ESE+T datasheet, MAX4511ESE+T pinout, MAX4511ESE+T application, or MAX4511ESE+T equivalent, key selection criteria include verified fault-protection behavior under ±40V power-off conditions, confirmed 10mA COM output sourcing/sinking capability during faults, guaranteed ≤0.5nA COM off-leakage at +25°C, and pin compatibility with DG201/DG411 for legacy board upgrades.
Technical Context
The MAX4511ESE+T implements dual-FET parallel switching architecture-N-channel and P-channel MOSFETs driven in phase-to achieve low on-resistance while enabling true rail-to-rail analog conduction. Its fault protection relies on dedicated comparators monitoring NC/NO pins against V+ and V−, triggering automatic high-impedance isolation when signals exceed rails by ~50mV.
During fault events, internal "booster" FETs (P2/N2) actively clamp the COM terminal to V+ or V−, delivering up to ±10mA to the load without glitching. Power-off protection remains active: NC/NO terminals become virtual open circuits, tolerating ±40V faults even with V+/V− unpowered.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 175Ω at ±15V - ensures minimal signal attenuation in precision sensor front-ends |
| Fault protection range | ±36V with power applied, ±40V with power off - protects against transient overvoltages in industrial control I/O |
| Off-leakage current (COM) | 0.5nA at +25°C - preserves accuracy in high-impedance measurement paths |
| Supply range | ±4.5V to ±18V dual or +9V to +36V single - supports wide-range industrial power architectures |
| Logic compatibility | TTL/CMOS thresholds (0.8V/2.4V) at ±15V or +12V - eliminates level-shifting in mixed-signal control logic |
| Turn-on/off time | 500ns/750ns typical at ±15V - enables reliable switching in medium-speed multiplexing applications |
| Channel matching (∆RON) | 10Ω max - critical for matched gain/attenuation in differential or multi-channel signal routing |
Pinout & Package
MAX4511ESE+T uses a 16-pin narrow SO package (SOIC-N16), 3.9mm width, with standard 1.27mm pitch. Pin 12 is N.C.; GND (pin 5) connects digital ground only; V− (pin 4) ties to GND for single-supply use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (pins 1,8,9,16) | Digital control inputs | Accept TTL/CMOS logic; drive internal switch state (ON/OFF) for respective channels |
| COM1–COM4 (pins 2,7,10,15) | Analog common terminals | Non-fault-protected signal path junctions; connect to ADC inputs, DAC outputs, or sensor interfaces |
| NC1–NC4 (pins 3,6,11,14) | Fault-protected normally closed analog terminals | Carry protected signals up to ±36V; open-circuit during fault to isolate downstream circuitry |
| V+ (pin 13) | Positive supply input | Powers analog switches and logic; internally connected to substrate; sets logic thresholds |
| V− (pin 4) | Negative supply input | Required for dual supply; tie to GND for single-supply operation (+9V to +36V) |
| GND (pin 5) | Digital ground reference | Reference for logic inputs only; no analog signal ground connection |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Passes signals from V− to V+ without clipping - essential for full-scale sensor or audio signal routing |
| Power-off fault protection | Maintains ±40V NC/NO tolerance with zero supply - safeguards during brownouts or hot-swap events |
| No supply sequencing required | V+ and V− may be powered in any order - simplifies power management in multi-rail systems |
| Break-before-make timing | Not applicable - MAX4511 is NC-only; avoids signal shorting during channel switching |
| Low power consumption | <2mW typical - suitable for battery-backed or energy-constrained industrial nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fault-protected analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4511CSE+ | 0°C to +70°C operating range vs. −40°C to +85°C for MAX4511ESE+T; otherwise identical electrical specs and pinout | Suitable for commercial-grade instrumentation but not extended-temperature industrial or avionics deployments | Select MAX4511CSE+ only if ambient temperature stays within 0°C–70°C and cost sensitivity outweighs thermal margin needs |
| ADG467BRZ | Higher 200Ω max on-resistance; ±20V fault protection (vs. ±36V); requires external charge-pump for rail-to-rail operation | Lacks integrated booster FETs - cannot source/sink 10mA during fault; limited to lower-voltage industrial systems | Choose ADG467BRZ only when supply rails are constrained to ±15V max and fault voltages remain below ±20V |
Compared with MAX4511CSE+, the MAX4511ESE+T provides extended temperature reliability and broader fault margin; compared with ADG467BRZ, it delivers superior fault voltage tolerance, active rail clamping, and lower on-resistance-making it the sole choice for harsh-environment, high-voltage signal routing.

FAQ
What is the maximum fault voltage the MAX4511ESE+T can withstand with power removed?
The MAX4511ESE+T sustains ±40V faults on its NC/NO terminals even when V+ and V− are unpowered. This is achieved via internal high-impedance isolation circuitry that activates automatically during power loss, making the MAX4511ESE+T ideal for hot-swap or brownout-prone systems where transient overvoltages may occur during shutdown sequences.
Does the MAX4511ESE+T require external components to achieve rail-to-rail operation?
No. The MAX4511ESE+T achieves true rail-to-rail signal conduction (V− to V+) without external charge pumps or level shifters. Its dual-FET architecture and internal gate-drive translation enable full analog swing across the entire supply range, as verified in the datasheet's Typical Operating Characteristics curves for on-resistance vs. VCOM.
Can the COM pins of the MAX4511ESE+T be used as inputs or outputs interchangeably?
Yes. Per the datasheet Pin Description, COM and NC pins are functionally interchangeable as long as voltages stay within V− to V+. Signals pass bidirectionally with identical on-resistance and leakage performance - a key advantage for flexible PCB layout and signal-path reconfiguration in modular data acquisition hardware using the MAX4511ESE+T.
How does the MAX4511ESE+T behave during a positive overvoltage fault on an NC pin?
When an NC pin exceeds V+ by ~50mV, the MAX4511ESE+T's high-fault comparator disables the main N1/P1 switching FETs, isolating the NC pin. If the switch is ON, the P2 "booster" FET sources up to +10mA from V+ to the COM pin, clamping its voltage precisely to V+ - eliminating output glitches and ensuring clean recovery once the fault clears.
Is the MAX4511ESE+T pin-compatible with non-fault-protected industry-standard switches?
Yes. The MAX4511ESE+T shares identical pinout and footprint with DG201, DG411, and other industry-standard quad SPST switches. However, only NC/NO pins are fault-protected - COM and IN pins retain standard CMOS characteristics and require adherence to absolute maximum ratings, as explicitly stated in the MAX4511ESE+T datasheet.
