Product details
Overview
MAX4511CSE+ 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 TTL/CMOS-compatible logic inputs-designed for industrial data acquisition systems requiring robust signal path integrity during overvoltage transients.
For engineers reviewing the MAX4511CSE+ datasheet, MAX4511CSE+ pinout, MAX4511CSE+ application, or MAX4511CSE+ equivalent, key selection criteria include fault-protection voltage range (±36V with power applied), rail-to-rail analog signal support up to ±14V, matched on-resistance (≤10Ω between channels), low off-leakage (0.5nA at +25°C), and compatibility with ±4.5V to ±18V dual or +9V to +36V single supplies.
Technical Context
The MAX4511CSE+ implements dual-FET parallel architecture (N- and P-channel) per switch channel, enabling low on-resistance while maintaining rail-to-rail conduction. Fault detection uses dedicated comparators monitoring NC/NO pins against V+ and V−; upon overvoltage (>±36V), internal FETs disconnect the terminal and activate booster FETs to clamp COM output to the appropriate supply rail.
During fault conditions, the device delivers up to ±10mA from V+/V− to the COM pin while isolating NC/NO with nanoamp-level leakage. Power-off fault protection extends to ±40V, and all four switches default to OFF state when unpowered-ensuring fail-safe signal path isolation without external control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) configuration - all four switches conduct when logic input = LOW. |
| Fault Protection | ±36V on NC/NO pins with power applied; ±40V with V+/V− = 0 - protects against transient overvoltages without latch-up or damage. |
| On-Resistance | 175Ω max at ±15V supplies - ensures minimal signal attenuation and thermal drift in precision analog paths. |
| On-Resistance Match | 10Ω max between channels - critical for multi-channel instrumentation where gain/offset matching matters. |
| Off-Leakage Current | 0.5nA at +25°C, 10nA at +85°C - preserves high-impedance sensor node integrity and ADC input accuracy. |
| Supply Range | ±4.5V to ±18V dual or +9V to +36V single - supports legacy ±15V industrial rails and modern high-voltage single-supply systems. |
| Logic Thresholds | +0.8V (LOW), +2.4V (HIGH) - guarantees interoperability with both TTL and CMOS drivers across full supply range. |
Pinout & Package
MAX4511CSE+ is housed in a 16-pin narrow SO (SOIC-N) package with 1.27mm pitch, JEDEC MS-012AC compliant, 10.2mm × 5.3mm footprint, and exposed pad not present.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital logic control inputs - active-low enables NC path conduction; TTL/CMOS compatible. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - non-fault-protected; must remain within V− to V+ range. |
| 3, 6, 11, 14 | NC1–NC4 | Fault-protected normally closed analog terminals - withstand ±36V faults and auto-isolate during overvoltage. |
| 4 | V− | Negative analog supply - connect to GND for single-supply operation (+9V to +36V). |
| 13 | V+ | Positive analog/digital supply - powers internal logic and gate drivers; internally tied to substrate. |
| 5 | GND | Digital ground reference - no analog signal reference; ESD diodes connect to V+ and V−. |
| 12 | N.C. | No internal connection - leave unconnected; no routing or thermal consideration required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ (e.g., ±14V with ±15V supplies) without clipping or distortion. |
| Fault-protected NC terminals | NC pins survive ±36V faults with zero current injection into COM; eliminates need for external clamping diodes. |
| All-switches-off on power loss | Guaranteed open-circuit state when V+ or V− is removed - prevents unintended signal coupling in brownout/failure modes. |
| Break-before-make timing | Not applicable - MAX4511 is NC-only; MAX4513 provides 50–100ns BBM delay, but MAX4511 has no transition overlap risk. |
| Low power consumption | <2mW typical at +25°C - enables use in battery-backed or thermally constrained industrial modules. |
Applications
| Industrial Data Acquisition | Avionics Signal Routing |

Use Scenario: Isolating 4–20mA transmitter outputs from PLC analog inputs during hot-swap maintenance or module replacement. IC Role / Device Role / Timing Role: Fail-safe analog interface switch that defaults to connected (NC) during power-up, then opens only upon validated controller command. Use Value: All-switches-off on power removal prevents current loop disruption during field-replaceable module insertion/removal - meeting IEC 61000-4-5 surge immunity requirements. |
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 |
|---|---|---|---|
| MAX4511ESE+ | Extended temperature range (−40°C to +85°C) vs. MAX4511CSE+ (0°C to +70°C); identical pinout, electrical specs, and fault protection. | Suitable for outdoor or automotive-adjacent industrial enclosures where ambient exceeds +70°C. | Select MAX4511ESE+ when operating temperature exceeds 70°C; otherwise MAX4511CSE+ offers cost advantage for commercial-grade environments. |
| ADG467BRUZ | Quad NC switch with ±20V fault protection (vs. ±36V), 120Ω max RON, but no rail-to-rail output clamping during fault - requires external supply-rail limiting. | Applicable where lower fault voltage margin is acceptable and tighter on-resistance is prioritized over fault resilience. | Choose ADG467BRUZ only if system-level fault exposure is limited to ±20V and board space allows external clamping components. |
Compared with MAX4511ESE+, the MAX4511CSE+ trades extended temperature capability for lower cost in controlled environments; compared with ADG467BRUZ, it delivers superior fault resilience and integrated rail clamping-reducing BOM count and layout complexity in harsh industrial settings.

FAQ
What is the maximum fault voltage the MAX4511CSE+ can withstand on its NC pins?
The MAX4511CSE+ withstands ±36V on NC pins with power applied (V+ and V− active), and ±40V when powered down (V+ = V− = 0). This is specified in the Absolute Maximum Ratings table and verified under Note 2 of the datasheet. Exceeding these limits risks permanent damage. The MAX4511CSE+ does not protect COM or IN pins-those must remain within V− to V+.
Is the MAX4511CSE+ pin-compatible with the DG201 series?
Yes, the MAX4511CSE+ is explicitly pin-compatible with the industry-standard DG201/DG202/DG213 family, as stated in the General Description. Pin mapping (IN, COM, NC/NO, V+, V−, GND, N.C.) matches exactly in the 16-pin SO package. However, unlike the DG201, the MAX4511CSE+ adds fault protection only on NC/NO pins-not on COM or IN-so existing layouts require verification of signal routing to avoid overvoltage on unprotected pins.
Does the MAX4511CSE+ support single-supply operation?
Yes, the MAX4511CSE+ 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 on NC pins-are fully specified and tested under single-supply conditions (see "ELECTRICAL CHARACTERISTICS-Single +12V Supply"). Logic thresholds remain TTL/CMOS-compatible across this range.
What happens to the MAX4511CSE+ switches during power-down?
When power is removed from the MAX4511CSE+, all four switches automatically turn OFF and present an open circuit at NC and COM terminals. The NC pins become virtual open circuits with nanoamp-level leakage, maintaining ±40V fault protection even with no supply. This fail-safe behavior is inherent to the architecture and requires no external pull-downs or control sequencing.
Can the MAX4511CSE+ handle rail-to-rail signals without distortion?
Yes, the MAX4511CSE+ supports true rail-to-rail analog signal handling: signals from V− to V+ pass through the NC–COM path with minimal distortion or clipping. This is enabled by its dual-FET (N+P channel) topology and internal gate-drive design. Measured on-resistance remains flat across the full range (see Typical Operating Characteristics Figure MAX4511-01), and output clamping during faults ensures unambiguous rail-aligned levels.
