Product details
Overview
MAX4511ESE+ from Maxim Integrated is a quad, normally closed (NC), fault-protected SPST analog switch designed for high-reliability signal routing in industrial and avionics systems. It supports ±4.5V to ±18V dual supplies or +9V to +36V single supply, delivers rail-to-rail signal handling, features 175Ω max on-resistance at ±15V, and provides ±36V fault protection on NC/NO pins with power applied. Its four independently controlled switches protect against overvoltage faults during power-up/down while maintaining unambiguous rail-clamped outputs.
For engineers reviewing the MAX4511ESE+ datasheet, MAX4511ESE+ pinout, MAX4511ESE+ application, or MAX4511ESE+ equivalent, key selection criteria include fault-protection voltage range (±36V), on-resistance matching (≤10Ω), COM output current capability (±10mA during fault), and compatibility with legacy DG201/DG213 layouts in harsh-signal environments.
Technical Context
The MAX4511ESE+ uses parallel N- and P-channel FET architecture-unlike traditional triple-FET fault-protected switches-to achieve low on-resistance and true rail-to-rail conduction. Two comparators continuously monitor NC/NO pin voltages against V+ and V−; when a fault exceeds ±36V (or ±40V with power off), internal boost FETs clamp COM to the appropriate supply rail while isolating the faulted terminal.
During normal operation, logic inputs (IN1–IN4) control switch states with TTL/CMOS-compatible thresholds (0.8V/2.4V at ±15V). The COM pins are not fault-protected and must remain within V− to V+; only NC/NO terminals tolerate overvoltage. All four switches turn off automatically when power is removed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5V to ±18V dual or +9V to +36V single - enables flexible system-level power architecture without sequencing constraints. |
| On-Resistance (RON) | 175Ω max at ±15V - ensures minimal signal attenuation and thermal drift in precision analog paths. |
| Fault Protection | ±36V on NC/NO pins with power applied; ±40V with power off - protects downstream circuitry during transients or miswiring. |
| Off-Leakage Current | 0.5nA at +25°C, 10nA at +85°C - preserves signal integrity in high-impedance data acquisition front-ends. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V low / 2.4V high at ±15V) - interoperable with standard microcontroller GPIOs and FPGA I/O banks. |
| Turn-On/Off Time | 500ns / 750ns typical at ±15V - supports medium-speed multiplexing in ATE and process-control scanning. |
| Charge Injection | 1.5pC typical - minimizes settling error in sample-and-hold and switched-capacitor circuits. |
Pinout & Package
MAX4511ESE+ is housed in a 16-pin narrow SO package (SOIC-N), 3.9mm × 9.9mm body, 1.27mm pitch, with exposed pad not present. Pin 12 is no-connect (N.C.). GND (pin 5) serves digital ground reference only; analog signal paths are fully isolated from ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (pins 1, 8, 11, 14) | Digital control inputs | Accept TTL/CMOS logic to enable/disable respective NC switches; high = open, low = closed (normally closed configuration). |
| COM1–COM4 (pins 2, 7, 10, 15) | Analog common terminals | Non-fault-protected signal path endpoints; must be kept within V− to V+ to avoid ESD diode conduction. |
| NC1–NC4 (pins 3, 6, 13, 16) | Fault-protected normally closed analog terminals | Withstand ±36V faults; become high-impedance during overvoltage; source/sink up to ±10mA via booster FETs when switch is ON and fault occurs. |
| V+ (pin 13) | Positive supply input | Powers internal logic and gate drivers; also connected to substrate; sets logic thresholds and reduces RON when increased. |
| V− (pin 4) | Negative supply input | Required for dual-supply operation; connect to GND for single-supply mode (+9V to +36V); increases gate drive strength to lower RON. |
| GND (pin 5) | Digital ground reference | No analog signal reference; used only for logic-level translators and ESD diode return paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Signals from V− to V+ pass unattenuated through NC–COM path; essential for full-scale sensor and DAC interface applications. |
| Automatic power-off fault isolation | All NC terminals become virtual open circuits with ±40V tolerance when V+ and V− are unpowered - eliminates need for external protection during maintenance or brownout. |
| Break-before-make timing (MAX4513 only) | Not applicable to MAX4511ESE+ - this feature is exclusive to MAX4513's mixed NO/NC configuration; MAX4511ESE+ has pure NC topology with no BBM requirement. |
| Pin compatibility with DG201/DG213 | Identical pinout to industry-standard non-fault-protected switches - allows drop-in replacement in existing PCBs where NC-only routing suffices. |
| Low power consumption | <2mW typical at ±15V - enables use in thermally constrained modules and battery-backed instrumentation without cooling overhead. |

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+ | Same electrical specs but rated for 0°C to +70°C industrial temperature range; lacks extended -40°C to +85°C qualification. | Suitable for commercial-grade instrumentation but not automotive or outdoor industrial deployments requiring wide-temperature reliability. | Select MAX4511ESE+ for applications operating beyond +70°C ambient or requiring AEC-Q200-aligned thermal cycling performance. |
| ADG467BRZ | Quad NC switch with ±20V fault protection (vs. ±36V), higher 200Ω max RON, and no rail-to-rail clamping during fault - COM floats instead of sourcing/sinking. | Applicable in lower-voltage industrial systems but cannot replace MAX4511ESE+ in ±36V fault-critical avionics or process-control interfaces. | Choose MAX4511ESE+ where ±36V fault margin, rail-clamped COM output, and sub-175Ω RON are mandatory design requirements. |
Compared with MAX4511CSE+, MAX4511ESE+ extends operational temperature range and improves long-term reliability in thermally aggressive environments; compared with ADG467BRZ, it delivers superior fault voltage margin, active rail clamping, and tighter on-resistance matching - critical for precision multiplexing and safety-critical signal routing.

FAQ
What is the maximum fault voltage the MAX4511ESE+ can withstand on its NC pins?
The MAX4511ESE+ withstands ±36V on NC pins with power applied and ±40V with V+ and V− unpowered. This is specified in the Absolute Maximum Ratings table and verified across the full -40°C to +85°C operating range. Exceeding these limits-even briefly-may cause irreversible damage, as the device is not a surge protector or lightning arrestor.
Is the MAX4511ESE+ pin-compatible with the DG201 series?
Yes, the MAX4511ESE+ is explicitly pin-compatible with the DG201/DG202/DG213 family per the datasheet's "Pin Compatibility" section. Its 16-pin narrow SO footprint matches DG201's layout, enabling direct PCB replacement in existing designs - provided the application requires only normally closed (NC) switching and operates within the MAX4511ESE+'s supply and fault-protection specifications.
Does the MAX4511ESE+ support single-supply operation?
Yes, the MAX4511ESE+ operates from a single +9V to +36V supply by connecting V− to GND. Electrical characteristics-including 175Ω max on-resistance, 0.5nA off-leakage at +25°C, and ±36V fault protection-are fully specified and tested under single-supply conditions, as confirmed in the "ELECTRICAL CHARACTERISTICS-Single +12V Supply" tables.
Why does the MAX4511ESE+ have no break-before-make timing specification?
The MAX4511ESE+ implements a purely normally closed (NC) switch architecture with no internal break-before-make circuitry. That timing parameter applies only to the MAX4513 variant, which integrates two NC and two NO switches on one die. Since MAX4511ESE+ contains four identical NC switches, there is no risk of short-through during state transition - eliminating the need for BBM delay specification.
Can the COM pins of the MAX4511ESE+ be overvolted safely?
No - COM pins are not fault-protected. Per datasheet Note 1, signals on COM exceeding V− or V+ are clamped by internal ESD diodes, risking permanent damage if forward current exceeds ±30mA. The MAX4511ESE+'s ±36V fault tolerance applies exclusively to NC/NO pins; COM must always remain within the V− to V+ supply rails during both normal and fault conditions.
